Answer:
what is the question
Step-by-step explanation:
Answer:
3x+4y=18 and 5x+2y=16
x=the cost of the sodas
y=the cost of the iced teas
then you do
3x+4y=18, and 10x+4y=32 (the equation is still equivalent to 5x+2y=16, you just doubled it)
next,
10x+4y=32
-3x-4y=-18 (once the y's match, make one negative and one positive)
which leaves you with:
7x=14
which means
x=2
Plug the x value back into the equation, for this I chose to plug it back into 3x+4y=18
3(2)+4y=18
6+4y=18
4y=12
y=3
so the final answer is x=2, and y=3

Nathan wants to draw a triangle. He knows that the lengths of the two shorter sides are 5 inches and 7 inches. What is a possible length of the third side? Group of answer choices
Answer:
8.6
Step-by-step explanation:
From the above question, we know that the length of the third side is the longest. Hence, we apply Pythagoras Theorem
c² = a² + b²
a = 5, b = 7
c = Third side
c = √a² + b²
c = √5² + 7²
c = √25 + 49
c = √74
c = 8.602325267
Approximately c = 8.6
Possible length of the third side = 8.6

Write the rule for the linear function. Remember a function rule is written using
Answer:
The rule for the linear function will be:
f(x) = -2x+1
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 as shown in the attached graph
Taking two points
(0, 1)(1, -1)Finding the slope between (0, 1) and (1, -1)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [-1 - 1] / [1 - 0]
= -2 / 1
= -2
Thus, the slope of the line = m = -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 = 1
Thus, the y-intercept b = 1
Now, substituting m = -2 and b = 1 in the slope-intercept form of linear function
y = mx+b
y = (-2)x + 1 ∵ m = -2, b = 1
y = -2x+1
f(x) = -2x+1
Therefore, the rule for the linear function will be:
f(x) = -2x+1
LMNP is a rectangle. Find the value of x and the length of each diagonal.
LN = 7x + 11 and MP = 9x-5
X= ???
Answer:
Step-by-step explanation:
The diagonals of a rectangle are congruent, thus
MP = LN , substitute values
9x - 9 = 7x + 9 ( subtract 7x from both sides )
2x - 9 = 9 ( add 9 to both sides )
2x = 18 ( divide both sides by 2 )
x = 9
LN = 7x + 9 = (7 × 9) + 9 = 63 + 9 = 72
MP = 9x - 9 = (9 × 9) - 9 = 81 - 9 = 72

8+ 6t-3t+ t
Answer:
4(2+t)
Step-by-step explanation:
A term is a single mathematical expression. We can see in this expression there are four terms, each separated by an operation:
8, 6t, -3t, and 1.
Coefficients are the numbers that multiply variables. You can also just think of them as the number in front of any variable. Here we see we have two terms with variables:
6t, -3t
and therefore our coefficients are:
6, -3
Constants are numbers that are, well, constant - you could also just think of them as "normal" numbers. We can see in this expression you have two:
8, 1
Like terms are terms of the same type. We have two like terms with a variable in them:
6t, -3t
and two like terms that are constants:
8, 1

circular swimming pool has a diameter of 30 feet and a depth of 5 feet. Which equation can be used to find V, the volume of the swimming pool, in cubic feet?
Answer:
V = hπr^2
V = 5 X π X 15^2
V = 3534.29173
V = 3534.2 cubic feet
The equation that can be used to find the volume V of the swimming pool is πr²h
The swimming pool is circular and has a diameter of 30 feet and a depth of 5 feet.
This simply means the swimming pool follows the shape of a cylinder. The
two bases are circular and has a height of 5 feet.
Therefore, the volume of the swimming pool in cubic feet is the volume of a cylinder.
volume = πr²h
where
r = radius = 30 / 2 = 15 feet
h = 5 feet
volume = 3.14159 × 15² × 5 = 3.14159 × 225 × 5 = 3534.28875 = 3534.3 ft³

Hey, Its the same person. This is Algebra 2. Please Help!
Answer:
first option
Step-by-step explanation:
Given
f(x) = [tex]\frac{2x^2+5x-12}{x+4}[/tex] ← factorise the numerator
= [tex]\frac{(x + 4)(2x-3)}{x+4}[/tex] ← cancel (x + 4) on numerator/ denominator
= 2x - 3
Cancelling (x + 4) creates a discontinuity ( a hole ) at x + 4 = 0, that is
x = - 4
Substitute x = - 4 into the simplified f(x) for y- coordinate
f(- 4) = 2(- 4) - 3 = - 8 - 3 = - 11
The discontinuity occurs at (- 4, - 11 )
To obtain the zero let f(x) = 0, that is
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]
There is a zero at ( [tex]\frac{3}{2}[/tex], 0 )
Thus
discontinuity at (- 4, - 11 ), zero at ( [tex]\frac{3}{2}[/tex], 0 )

a handful of coins has the value of 1 dollar and 79 cents there are 3 times as many dimes as quarters and 5 more pennies than dimes if there are only 3 types of coins how many of each type of coin are there
Answer:
3 Quarters 9 dimes 14 pennies
Step-by-step explanation:
so dimes are x, quarters are y, and pennies are z. Next we know that x*3 y is what dimes are and 5 more pennies then dimes so z+5. Now we do 3 quarters since thats about 100 but less then 3*3=9 so 190 we have 90+75 cents now then we add 14 the cursed number lol but we add 14 because 9+5 is 14 and there are 5 more pennies then dimes.

56 first-graders and 24 other students attended a school assembly. What percentage of the students at the assembly were first-graders?
Answer:
80%
Step-by-step explanation:
We can write the ratio of first graders to students as 56:24.
We have to find the total amount of students so we add those two up and we get 70
Out of 70, there are 56 first graders, so we can write that as a fraction which will be 56/70
To get this to a percent, we have to get it so the denominator is 100, I can do some weird thing, multiplying a decimal over decimal to get to the answer, but that isn't what you would most likely do
The best thing to do in this scenario is to simplify this equation so it has a denominator of 10, so we do divide by 7 on the bottom, divide by 7 on the top, and we get the more simplified fraction, 8/10. And 8/10 is also equal to 80/100 which makes the percent 80%

Answer:
What are the choices and what grade level going to 4th-12th
Step-by-step explanation:
The speed is the distance covered by an object at a particular time. It will take 1 and seven-tenths of the day to reach San Francisco.
What is speed?The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Speed = Distance Covered / Time taken
Given that the speed during the entire journey is 60 miles per hour and you drive for 8 hours per day. Therefore, the distance that you can cover in a day is,
Distance covered in a day = Speed × Time
= 60 miles per hour × 8 hours per day
= 480 miles per day
Now, by road the distance between Washington, DC, and San Francisco, California is 812.5 miles. Therefore, the number of days it would take to reach San Francisco is,
Number of days
= Total Distance to be Covered / Distance covered in a day
= 812.5 miles / 480 miles per day
= 1.7 days
Hence, it will take 1 and seven-tenths of the day to reach San Francisco.
