Five crates hold 20 pounds of materials. jen set up this problem to find how many pounds of materials one crate holds: 5/20 = 1/x which of the following best describes how jen will continue to solve the problem? cross multiply, 5x = 20 cross add, 5 + x = 21 multiply across, 5 = 20x add across, 6 = 20x

After setting up the two ratios as a proportion, cross multiply to find the value of x.

Cross multiply, 5x = 20

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
