6x + 7 = 8x - 15
7 = 2x - 15
22 = 2x
11 = x
It would seem that the 25% down and 25% increase would cancel each other out and the shoes would remain $60
Answer:
76
Step-by-step explanation:
N=Novels
M=Months
4N = 1M
?? = 19M
4N × 19M = 76 NM
76 NM ÷ 1M

Answer: The flagpole is 12.1 feet high.
Step-by-step explanation:
We can solve this by using a ratio:
Actual height to shadow length. The fractions must have the same equivalent values.
5.5/10 = x/22 Cross multiply the numerator on the left times the denominator on the right, and the denominator on the left by the numerator on the right:
5.5(22) = 10x
121 = 10x Divide both sides by 10. (10s "cancel" on the right)
12.1 = x
The flagpole is 12.1 feet high.
