Answer:
7.8125 gallons
Step-by-step explanation:
Because 5 gallons would cover 1600 square-foot wall so 1 gallon would cover:
1600 / 5 = 320 square-foot wall.
So to cover 2500 square foot-wall, we need in total of:
2500 / 320 = 7.8125 gallons of paint
Hope this can help you :3

Answer:
y = 5x + 12
Step-by-step explanation:
Use the formula: y - y1 = m(x - x1)
Plug in all numbers into your equation: y - 7 = 5(x - -1)
Minus with a minus becomes a positive: y - 7 = 5(x + 1)
Distribute: y - 7 = 5x + 5
Add 7 to both sides: +7 +7
Answer: y = 5x + 12
Answer:
