Answer:
28 quarters and 5 dimes
7(Q)+5(D)
7(4)+5(10)
28Q 50D Q=quarters D=dimes
it would be more efficient to do the substitution method bc its faster and easier
3/4 (x+8)=9
3/4x+6=9
-6
3/4x=3
X=4
Check
3/4(4+8)=9
3/4 (12)=9
9=9
A) is 5 months
b) is option 1 difference of 40
Get x to one side by subtracting 2x by 5x.
-3x = -30
Then divide both sides by -3 to get x = 10
Have a nice day.
