Answer:
8/7A - C = B
Step-by-step explanation:
A= 7/8(B+C)
Multiply both sides by 8/7
8/7A = B + C
Subtract C
8/7A - C = B
42 + 6 divided by 2 equals 24
Answer:
A = 3W² + W + 1/8πW²
Step-by-step explanation:
rectangular window is L x W
semicircle is 1/2 πr²
r = 1/2 W
L = 3W + 1
A = W(3W + 1) + 1/2 π(1/2W)²
A = 3W² + W + 1/8πW²
Dividing by a fraction is the same as multiplying by its reciprocal. So dividing by 2/5 will give you the same answer as multiplying by 5/2.
The bill after applying the coupon = 31.84*(85%) = 27.064
