Ahouse painter can paint 2550 ft² in 3 h.

what is the house painter’s painting rate?

a.)550 ft²/h

b.)850 ft²/h

c.)1700 ft²/h

d.)7650 ft²/h

The answer is B. 850

2550 ÷ 3 = 850, a here is how I did it. 3 can't go into 2, but it can go into 25 8 times for 24, so put your 8 above the first 5. 5 - 4 = 1 so drop you 1 down along with you 5 for 15. 3 can go into 15 5 times so put your five next to your 8 then solve. 15 - 15 = 0. Add you 0 next to your 5. Then, your answer will be 850.

associative property of multiplication

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
