Step-by-step explanation:
First problem:
blank 2) on the left: PR = PQ + QR
blank 3) on the right: Replace PR in statement 1) with what we just completed in statement 2. Therefore:
2PQ = PR
2PQ = PQ + QR
blank 4) on the right: Subtract PQ from both sides, therefore
2PQ = PQ + QR
2PQ - PQ = PQ + QR - PQ
PQ = QR
Given :
Tammy saved nickels and pennies in a jar the ration of nickels to pennies was 2 : 5 .
To Find :
If there where 70 nickels in the jar how many coins are there in all.
