Answer:
80
Step-by-step explanation:
16 × 5 = 80
base × height = area
X+y=30
2x-3y=5
y=30-x
2x-3(30-x)=30
2x-90+3x=30
5x=120
x=24
y=30-x
y=30-24
y=6
The positive difference between the two numbers is 18.
Area of TV screen = 15 x 20 = 300 square feet
Cost of TV screen cover = 25 cents per square foot
