Answer:
The number rounded to the nearest tenth is 15.1
Step-by-step explanation:
<u>Step 1: Make an equation</u>
When a number is decreased by 27%, the result is 11.
x * (1 - 0.27) = 11
<u>Step 2: Solve inside the parenthesis</u>
x * (1 - 0.27) = 11
x * 0.73 = 11
<u>Step 3: Divide both sides by 0.73</u>
0.73x / 0.73 = 11 / 0.73
x = 15.1
Answer: The number rounded to the nearest tenth is 15.1
Answer:
15.1
Step-by-step explanation:
Decreased by 27%
100 - 27 = 73% of the original
73/100 × X = 11
X = 1100/73 = 15.06849315

Answer:
10 = c
Step-by-step explanation:
Distribute -4 to the parentheses:
8 = 8c - 4(c + 8)
8 = 8c - 4c - 32
Add like terms:
8 = 4c - 32
Add 32 to both sides:
40 = 4c
10 = c
