Answer:
x = 7
Step-by-step explanation:
A rhombus is a parallelogram where all sides are equal. Therefore, as we know two sides are equal to 7x+8 and 9x-6, we can say that
7x+8 = 9x - 6
subtract 7x from both sides to put the variable on one side
2x - 6 = 8
add 6 to both sides to isolate the variable and its coefficient
2x = 14
divide both sides by 2 to isolate x
x = 7
a) We have that the discount is 65 %
Scott buys a jacket for $150
First, we will calculate the discount

then we need to subtract the quantity calculated above from the original price

After the markdown Scott paid $52.5
b.
In order to know the taxes first, we need to calculate the 5% of $52.5

then we will sum the 5% plus the price after the markdown

The total cost of the jacket is $55.125
It represents the entire data set and the triangles inside the circle graph represent part of the whole data set
Divide 5/8 by 150, to see how thick each is, that'll give you 150 even pieces that add up to 5/8
