Answer:

  10 years old

Step-by-step explanation:

The difference in ages is 60 -30 = 30 years. When mom was 4 times daughter's age, the difference in their ages was 3 times the daughter's age.

The age difference was 30 years at that time, so the daughter was 10 years old.

Campbell’s paycheck was $257.29. She put 1/4 of her paycheck into a savings account and used 1/3 of what was left to pay bills.
Stells [14]

Answer:

She has $128.65 left

Step-by-step explanation:

$257.29 x 1/4 = $64.32

$257.29 - $64.32 = $192.97

$192.97 x 1/3 = $64.32

$192.97 - $64.32 = $128.65

the value of n is both 5 times as much as the value of m and 36 more than the value of m. what are the values of n and m? explai
xenn [34]
We have to find the values of m and n. We know that the value of n is 5 times as much as the value of m : n = 5 m. Also n is 36 more than the value of m : n = m + 36. This is a system of equations. Of we substitute n = 5 m into the second equation: 5 m = m + 36; 5 m - m = 36; 4 m = 36; m = 36 : 4; m = 9. Finally: n = 5 * 9 ; n = 45. Answer: The values are n = 45 and m = 9.
