Answer: 61°
because this is a parallelogram
=> m∠X = m∠Z
⇔ 7x + 5 = 8x - 3
⇔ x = 8
with x = 8 => m∠X = 7.8 + 5 = 61°
Step-by-step explanation:
Solve for x:
(-4 x - 2) (x - 7) = 0
Split into two equations:
-4 x - 2 = 0 or x - 7 = 0
Factor constant terms from the left hand side:
-2 (2 x + 1) = 0 or x - 7 = 0
Divide both sides by -2:
2 x + 1 = 0 or x - 7 = 0
Subtract 1 from both sides:
2 x = -1 or x - 7 = 0
Divide both sides by 2:
x = -1/2 or x - 7 = 0
Add 7 to both sides:
Answer: x = -1/2 or x = 7

Answer:
you save $52.11 by shopping at the second store
Step-by-step explanation:
The total sale price at the second store is $240.95.
additional 10% off coupon for the second store for purchases over $200.00
10% discount on sale price is 240.95 * 10%

Total sale price after 10% discount =240.95 - 24.095=$216.86
First store sale price = $268.97
second store sale price = $216.86
Difference = 268.97 - 216.86 = 52.11
you save $52.11 by shopping at the second store
