Answer:

Step-by-step explanation:
First, we convert the mixed numbers into improper fractions:
, and
. Now, we multiply the fraction using the multiplication rule,
:
.
Thus, the product of the two given fractions is 55/14.
1224 / 12 = 102
He will be paying $102 a month for his TV
X = 15
X + 90 = 7x
X = 7x - 90
X - 7x = -90
-6x = 90
Divide both sides by -6
X = 15
Short side length = x
Medium side = x + 7
Long side = 5x
Total 49, so
x + x + 7 + 5x = 49
If you combine like terms:
7x + 7 = 49
Subtract 7 from both sides
7x = 42
Divide both sides by 7
x = 6 inches
