Answer:
x = 8
Step-by-step explanation:
(please verify) if line segment LM is congruent to line segment PN; then
9x - 25 = 5x + 7; subtract 5x from both sides
4x - 25 = 7; add 25 to both sides
4x = 32; divide by 4
x = 8
To solve a Linear equation we need to find the slope:
-4-1 / -2-8 =1/2
now that we have the slope we can find our x and y
y-1=1/2(x-8)
y=x/2-3

Step-by-step explanation:
30-3.12=26.88 divide that by 4 and you get 6.72
Multiply the amount of the discount by pairs of shoes:
21.75 x 7 = 152.25
Add that to the total she spent:
152.25 + 654.50 = 806.75
