When you are distributing, you are multiplying to each monomial
4(4a) = 16a
4(20b) = 80b
16a + 80b is your actual answer
hope this helps
A=90 degrees divide by 5
=18 degrees
2c+a=90
2c+18=90
2c=90-18
2c=72
divide each side by 2
c=36
therefore:
2c=72
b=4a+c
b=4(18)+36
b=72+36
b=108

Answer:
7/15 for dime
6/15 for pennies
Step-by-step explanation:
7/15 because 7+2+6=15 and there are 7 dimes so 7/15.
