Answer:

60 cents

Step-by-step explanation:

Let's call p the number of pennies that Reed has, and q the number of quarters. From here, you can set up the following system of equations:

p=q+8

p=5q

Now, you can substitute the second equation into the first:

5q=q+8

4q=8

q=2

Reed has two quarters, and therefore 10 pennies. Since each quarter costs 25 cents and each penny costs 1, 25*2+10*1=60 cents in total. Hope this helps!

Greg’s sister Ava is 4 years older than him. If the sum of Greg’s age and 2 times Ava’s age is 35, How old is Ava?
Fofino [41]

Answer:

13

Step-by-step explanation:

Create an equation: g+(G+4)(2)=35

Parentheses: g+2(G+4)=35

Distributive property: g+2g+8=35

Combine like terms: 3g+8=35

Subtractive property: 3g=27

Division property: g=9

Greg is 9. Since Ava is 4 years older you add 4 to find her age. Ava is 13. You take Ava’s age times 2 ( equals 26) then add Greg’s age (equals 35). And it should equal 35.
