Answer:
5% Increase
Step-by-step explanation:
560 * 0.05 = 28
560 + 28 = 588
20 percent of 100 is 20 so the dress is 80 on sale so you need 20 which is 25% of 80
20 plus 80 equal 100 the starting price
25%
Answer:
D
Step-by-step explanation:
To be an identity we require both sides of the equation to equate
A
8x + 9 ≠ 8x - 3 ← not an identity
B
7x - 2 = 8x + 4 - x = 7x + 4 ≠ 7x - 2 ← not an identity
C
11 - (2x + 3) = 11 - 2x - 3 = - 2x + 8 ≠ - 2x - 8 ← not an identity
D
5x + 8 - x = 6x - 2(x - 4), that is
4x + 8 = 6x - 2x + 8 = 4x + 8 ← both sides equate thus an identity
