first turn 25% into a decimal so it's easier to work with, the decimal for 25% is 0.25
then multiply the number by the decimal
12x0.25=3
then subtract your answer (3) from your starting number
12-3=9
12 dogs decreased by 25% leaves you with 9 dogs left.
if you are increasing, divide instead of multiply
The number that 18 is 45% of 40.
To find the number that 18 is 45% of, we can set up the following equation:
we can set up the following equation:
Given number is 18 and the percentage is 45%
18 = 0.45 * x
x=18/0.45
To solve for x, divide both sides of the equation by 0.45:
To solve for x, divide both sides of the equation by 0.45:
x = 18 / 0.45
x=40
By future Performing the calculation:
x = 40
We get the answer as 40.
Therefore, 18 is 45% of 40.

Answer:
E (b/3) +3
Step-by-step explanation:
3c =b
c+3 = ?
Solve the first equation for c
3c=b
Divide by 3
3c/3 = b/3
c = b/3
Now replace c with b/3 in c+3
c+3
(b/3) +3
Answer:
Answer E. is correct
Step-by-step explanation:
b = 3 * c --> c = 1/3 * b
c + 3 = 1/3 * b + 3 --> E.
thank you!!!!!
