0.7 + 0.4 + 0.6 + 0.4 = 2.1 is the perimeter
0.7 x 0.4 = 0.28
0.6 x 0.4 = 0.24
0.28 + 0.24 = 0.52 is the area
Hope that helped!
First getting x as a numerator rather than a denominator. Then grouping like terms by moving 5 from the left side to the right. Work below:
Nickels is 0,05 of dolar - n
dimes is 0,1 o dolar -d
quarters is 0,25 of dolar -q
dimes =2nickels
d=2n
quarters=2dimes
q=2d=4n
12,5=n(0,05)+2n(0,1)+4n(0,25)
12,5=0,05n+0,2n+n
12,5=1,25n
n=10
q=4n=40
There are 40 quarters
