Answer:
There are 34 Tens and 68 Fives
Step-by-step explanation:
2X*5+X*10=680
Multiply 2X by 5 to get 10X.
10X+X*10=680
Multiply X by 10 to get 10X.
10X+10X=680
Since 10X and 10X are like terms, add 10X to 10X to get 20X.
20X=680
Divide each term in the equation by 20.
(20X)/(20)=(680)/(20)
Simplify the left-hand side of the equation by canceling the common factors.
X=(680)/(20)
Simplify the right-hand side of the equation by simplifying each term.
X=34 tens
68 fives
Prove:
34*10= 340
68*5= 340
340+340=680
Answer:
There are 34 tens and 68 fives because 34*5 + 68*10 = 680.
