Your answer would be -6 because
Volume is height times width times length so to find the height you just do the opposite. Using h as height we put the equation like so...
43.875=5 * 3.9 * h
Now divide and we get
2.25=h
Your answer is 2.25
If one side is 3 inches, the perimeter would be 5x3 which is 15. In terms of algebra, if one side is y, then the perimeter is 5y.
Let b represent the amount the boy put in the bank. Then (860-b) represents the amount he lent his parents. His earnings were ...
0.045b + 0.07(860 -b) = 51.95
-0.025b = 51.95 -0.07*860
b = -8.25/-0.025 = 330
The boy put $330 in the bank.
Okay I dislike improper fractions but the way to do this
see how many times the bottom number (denominator) goes into the top number (numerator)
4 can go into 15 3 times so 3 is your whole number
now you have 15-12=3 and that last three will be your next numerator
so your answer will be
3 3/4
