A pair of Jordans sold at retail for $180 and now sell for $330 after market. A. Is this a percent INCREASE or DECREASE, what is the PERCENT change?
Answer:
This is a percent INCREASE
The percent change is 83.33%
Step-by-step explanation:
Let us solve the question
∵ A pair of Jordans sold at retail for $180
∴ The initial price = 180
∵ Now it sells for $330 aftermarket
∴ The new price = 330
→ That means the new price is greater than the initial price
∵ The new price is greater than the initial price
∴ This is a percent INCREASE
∵ The percent of change = (amount of increase ÷ initial amount) × 100%
∵ The amount of increase = new price - initial price
∴ The amount of increase = 330 - 180 = 150
→ Substitute it in the rule of percent of increase above
∵ The percent change = [tex]\frac{150}{180}[/tex] × 100%
∴ The percent change = [tex]\frac{5}{6}[/tex] × 100%
∴ The percent change = 83.33%

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!

Lourdes plans to jog at least 1.5 miles. Write an inequality and solve an inequality to find x, the number of hours Lourdes will have to jog. She is running at 3.75 mph
Answer:
1.5 ≤ 3.75x
Step-by-step explanation:
Given that:
Distance, D to jog is atleast 1.5 miles
D ≥ 1.5 miles
x = number of hours to jog
Jog rate = 3.75 mph
Actual distance covered if jog last for X hours
Actual Distance = speed * time
Actual Distance = 3.75 * x = 3.75x
Hence,
D ≤ Actual distance
1.5 ≤ 3.75x
What is the answer to this ?

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).

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

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

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.

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
