Answer:
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
q = 40
n = 5(40) = 200
Step-by-step explanation:
Number of Nickels = n
Number of Quarters = q
$2.00 = $2 * 100 = 200 cent
Nickel = 5 cent
Quarter = 25 cent
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
5(5q) + 25q = 200
25q + 25q = 200
50q = 200
q = 200/5
q = 40
n = 5(40) = 200
Answer:
x = 10
Step-by-step explanation:
Divide both sides by 2.
(2x) / 2 = 20 / 2
x = 10
To find the percent of the monthly income that is savings, you will divide the amount saved by the total amount of income.

Answer:
7/12
Step-by-step explanation:
-15/9+9/4
We need to make them have the same denominator:
9x4= 36 so that is our new denominator
-15x4= -60
9x9=81
(Sorry if i dont make sense)
Now we have -60/36+81/36 which is equal to 21/36.
Now we simplify:
21/36=7/12
