Afloor plan of the house was drawn using a scale of 1cm: 1.5m. the family room in the plan has a length of 7.5m. what is the actual length of the family room?

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

step-by-step explanation: 4 cause 2+2=4

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
