Answer:
24 is 75% of 32
Step-by-step explanation:
To get the percent in decimal form we divide 24 by 32
24 ÷ 32 = 0.75
To get the decimal into a percent we multiply it by 100

M ( -2, 1)
Answer:
First number = 4
Second number = 9
Step-by-step explanation:
If the first number = x, the second number = x + 5.
The calculation can be expressed as follows:
x + 2(x + 5) = 22
First, expand the bracket 2(x + 5):
x + 2x + 10 = 22
Combine like terms:
3x + 10 = 22
Subtract 10 from both sides:
3x = 12
Divide both sides by 3:
x = 4
First number = 4
Second number = 4 + 5 = 9
