Answer:

Step-by-step explanation:

A + G + M = 740

A = G - 20

A = M - 120

Therefore,

G = A + 20

M = A + 120

Plug it in...

A + (A + 20) + (A + 120) = 740

Combine like terms

3A + 140 = 740

- 140 -140

3A = 600

/3 /3

A = 200

Double check

A = 200, G = 220, M = 320

200 + 220 + 320 = 740

If 9/10 is multiplied by 8/9, will the product be greater than either of the two factors?

Goshia [24]

No, both of the numbers are less than one whole and when you multiply them (I got 4/5) 4/5 is less than both of the factors.
