Answer:

w = 36 cm

L = 27 cm

Step-by-step explanation:

I am translating and I see that perimeter of rectangle is 126 cm and the base (assuming Length) is (3/4) the height.

P = 2(l+w)

$126=2((\frac{3}{4} w)+w)$

Divide both sides by 2, so you get

(3/4)w+(4/4)w=(126/2)

(7w/4)=63

Multiply both sides by 4,

7w=252, then divide both side by 7,

w = 36, Width is 36 cm, so Length is (3/4), which is L = 27 cm

Y varies directly with x, and y = 7 when x = 2. What is the value of y when x = 5?

____ [38]

Y varies directly with x" means y = constant * x or y = kx ----- (1)1. when x = -1/2, y = 2Put it in (1):2 = k * (-1/2)multiply by 2:4 = k * (-1)4 = -kk = -4y = -4x
"find the value of y when x= -0.3"y = -4x = (-4) * (-0.3) = 1.2

So for each problem, start with y = kxThey give you one x and one y value.Put it in y = kx and find k.Then put x = -0.3 and find y.

Consider the numbers 0, 10, 20, 30, and 40. Multiply each by 4 and compare the result to 60 to determine into which of the follo

Answer:b

Step-by-step explanation:

While this problem seems confusing, the answer is rather simple.

All you have to do is the reverse of what they are asking.

This is, substract 8 to 60 and then divide by 4:

$60-8 = 52\\\frac{52}{4} = 13$
