There are 3 numbers on the cube greater than 3 ( 4, 5, & 6)
This means he has a 3/6 = 1/2 chance of doing that.
He has a 1/2 chance of getting tails on the coin.
The probability of doing both would be the probability of the cube roll x the probability of the coin toss:
1/2 x 1/2= 1/4
The answer is 1/4
please help me with this and pls don't answer if you don't know. thank you!
Answer:
[tex]consider \: triangle \: BDE \\m<BCD = m<BED \\ angles \: of \: triangle \: sum \: up \: to \: 180 ° \\ (14x + 4)° + 55° + 51° = 180° \\ 14x = 180° - (4 + 55 + 51)° \\ 14x = 70° \\ x = \frac{70}{14} \\ x = 5[/tex]
Answer:
x = 5
Step-by-step explanation:
all angles at corners in parallelogram must add to 360
bcd = 51 thus angle at opposite corner (bed) must also equal 51
adding = 51 + 51 = 102
angles at ebc and edc are also equal to each other
edf = 55 and cbf = 55
adding 55+55 = 110
360 - 110 - 102 = 148
divide by 2 for angles ebf and cfd
148/2 = 74
now solve
14x + 4 = 74
14x = 70
x = 5
Good morning can y’all help me
Answer: The slope is -3
10 + 3x= 5 – 2x
What are the steps to finding the answer
Answer:
x=-1
Step-by-step explanation:
10+3x=5-2x (Add 2x to both sides)
10+5x=5 (Subtract 10 from both sides)
5x=-5 (Divide both side by 5)
x=-1
Answer:
x=-1
Step-by-step explanation:
10 + 3x= 5 – 2x
You first +2x on both sides
10 + 3x+2x= 5 – 2x+2x
subtract 10 on both sides
10-10+5x=5-10
Then divide 5 to isolate x
5 divide 5x=-5 divide 5
x=-1

Help plz anyone who’s good with slope?
Answer:
-3
Step-by-step explanation:
you go down from the dot left most and you count towards the line that the second dot falls on and count over too it
Answer:
slope = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m = [tex]\frac{-1-2}{2-1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3
State the probability that justifies each statement.
11. If 2x+19=27, then 2x=8
Answer:
100% true....
subtracting 19 from both sides brings you to 2x=8, so x=4
Step-by-step explanation:
Hey there!
2x + 19 = 27
SUBTRACT by 19 to BOTH SIDES
2x + 19 – 19 = 27 – 19
Cancel out: 19 – 19 because that gives you 0
KEEP: 27 – 19 because that gives you the value of 8
New EQUATION: 2x = 8
DIVIDE by 2 to BOTH SIDES
2x/2 = 8/2
CANCEL out: 2/2 because that gives you 1
KEEP: 8/2 because that gives you the value of x
“8/2 = x”
Answer: x = 4 ☑️
Good luck on your assignment and enjoy your day!

Jaylen earns the same amount of money each month. His telephone bill is 1 20 of his monthly earnings, and he pays a total of $840 each year for his telephone service. How much does Jaylen earn each month, in dollars? Do not include commas or dollar signs.
Given :
Jaylen earns the same amount of money each month.
His telephone bill is 1/20 of his monthly earnings, and he pays a total of $840 each year for his telephone service.
To Find :
How much does Jaylen earn each month, in dollars.
Solution :
Monthly payment of telephone bill is :
[tex]M = \$ \dfrac{840}{12}\\\\M = \$70[/tex]
Let, his monthly salary is A.
So,
[tex]M = \dfrac{A}{20}\\\\A = 20\times M\\\\A = 20 \times 70\\\\A = \$1400[/tex]
Therefore, Jaylen monthly income is $1400.

The table shows the relationship between the amount of candy bought (in pounds) and the total cost of the candy (in dollars) (5 points) Amount of Candy (pounds) 1 2 3 4 5 Cost (dollars) 65 120 195 220 300 Part A – Answer the question - Is cost proportional to pounds of candy bought? Why or why not? (You MUST show work to receive full credit!) Part B - – Write an equation to represent the relationship. The formula for the equation is y = kx
Answer:
65
Step-by-step explanation:
Answer:
(cost) is proportional to (amount of candy) because all of the values of the
ratios comparing cost to pounds are equivalent. All of the values of the ratios
are equal to . Therefore, every measure of (amount of candy) can be
multiplied by the number to get each corresponding measure of (cost).

Samantha created part of a table to show her savings. She saved at the same rate each week.
Samantha’s Savings
Week

4
Money Saved
$18
$24
Which graph shows this relationship?
On a coordinate plane, a graph titled Weekly Savings has weeks on the x-axis and money saved on the y-axis. Points (1, 8), (2, 16), (3, 18), and (4, 24) are plotted.
Answer:
B
Step-by-step explanation:
i did the test good luck <3
Graph [2] represents the correct relationship between Weeks and Money saved by Samantha.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is Samantha who created part of a table to show her savings. She saved at the same rate each week.
We have, Samantha’s Savings as -
Week 1 2 3 4
Money Saved A B $18 $24
Since she saves at the same rate every week, therefore, the slope of the line will be -
m = (24 - 18)/(4 - 3)
m = 6/1
m = 6
Then -
A = 6
B = 12
The graph [2] represents the correct graph.
Therefore, graph [2] represents the correct relationship between Weeks and Money saved by Samantha.

its the 2nd one
Step-by-step explanation:
y=mx+b
M=slope
B=y-intercept
Answer:
Slope: 5x Y-Intercept: -7

The slope is the rate at which it increases, the y-intercept is the point in the graph that crosses the y-axis
y=mx+b
mx = slope
b = y-intercept

Write the rule for the linear function. Remember a function rule is written using f(x)
Answer:
The rule for the linear function will be:
f(x) = 5/2x - 4
Step-by-step explanation:
We know that linear function can be represented using the slope-intercept formula
y = mx+b
where m is the slope and b is the y-intercept
Given the function is linear
Taking two points
(0, -4)(2, 1)Finding the slope between (0, -4) and (2, 1)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [1 - (-4)] / [2 - 0]
= 5 / 2
Thus, the slope of the line = m = 5/2
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = -4
Thus, the y-intercept b = -4
Now, substituting m = 5/2 and b = -4 in the slope-intercept form of linear function
y = mx+b
y = (5/2)x + (-4) ∵ m = 5/2, b = -4
y = 5/2x - 4
or
f(x) = 5/2x - 4 ∵ y = f(x)
Therefore, the rule for the linear function will be:
f(x) = 5/2x - 4
What is the answer to this ?

its B foe your question hope it helps

1)Identify the conjugate for 6 – 7√3 and explain your reasoning.
2)Multiply the radical expression 6 – 7√3 and its conjugate and write in simplified form. Show all your steps
3) Explain why we always get an integer when multiplying a radical expression by its conjugate? Provide your own appropriate example with supporting work that matches your explanation..
Answer:
1) The conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].
2) -111
3) It is because number and its conjugate have the same numbers but their second components are opposite to each other.
Step-by-step explanation:
1) A radical number of the form [tex]r = a + b\sqrt{c}[/tex], [tex]\forall \,a,b,c\in \mathbb{R}[/tex], where the first component is a non-radical real number which acts as a "pivot" and the second component is the radical component, which generates a "displacement" from pivot.
The conjugate of [tex]r[/tex] is a real number [tex]s = a - b\sqrt{c}[/tex], [tex]\forall \,a,b,c\in \mathbb{R}[/tex], which that is "pivot" plus "displacement" in the direction opposite to that of [tex]r[/tex]. We proceed to complement this explanation with the image attached below.
Then, the conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].
2) We proceed to performed all the need algebraic operation until result is found:
1) [tex](6+7\sqrt{3})\cdot (6-7\sqrt{3})[/tex] Given
2) [tex]6\cdot (6-7\sqrt{3})+7\sqrt{3}\cdot (6-7\sqrt{3})[/tex] Distributive property

5) [tex]36 +(-42)\cdot \sqrt{3}+42\cdot \sqrt{3}+(-49)\cdot 3[/tex] Definition of multiplication/[tex]-a\cdot b = (-a)\cdot b[/tex]/Definition of square root
6) [tex][36 +(-147)]+\sqrt{3}\cdot [42+(-42)][/tex] Commutative, associative and distributive properties/[tex]-a\cdot b = (-a)\cdot b[/tex]
7) [tex]-111+\sqrt{3}\cdot 0[/tex] Definition of subtraction/Existence of additive inverse
8) [tex]-111+0[/tex] [tex]a\cdot 0 = 0[/tex]
9) [tex]-111[/tex] Modulative property/Result
3) It is because number and its conjugate have the same numbers but their second components are opposite to each other.
