Answer:

\Huge \boxed{5x - 19}

\rule[225]{225}{2}

Step-by-step explanation:

A ——— B ——— C

AC = 8x - 20

AB = 3x - 1

BC = AC - AB

BC = (8x - 20) - (3x - 1)

Distributing negative sign.

BC = 8x - 20 - 3x + 1

Combining like terms.

BC = 5x - 19

\rule[225]{225}{2}

the length and width of a rectangle lot are in the ratio 3 to 2. if he perimeter of the lot is 530yards, find the length and wid
sergey [27]
Length = l = 3x
Width = w = 2x
P = 2l + 2w
P = 2(3x) + 2(2x)
530 = 6x + 4x
530 = 10x
53 = x
Length = 3x = 3(53) = 318 / 2 sides = 159
<span>Width = 2x = 2(53) = 212/ 2 sides = 106

the length of the lot is 159 yards
the width of the lot is 106 yards</span>

Write the expression as an inequality.
g100num [7]

For the park's ride sign, there are two pieces we need to look at.

1) "At least 44"

2) "No more than 74"

The first piece tells us anyone more than 44 inches can ride. 45 inches is okay, since 45 is more than 44 (45 > 44 is true). 44 works too since 44 ≥ 44 is true. So you can say a person's height - h that is more than 44 makes it true, h ≥ 44. We reverse its orientation and say that 44 ≤ h.

The second piece says if you are under 74 inches you can ride. "No more than" means we don't include 74 inches but 73 inches would be fine. With symbols, 74 < 74 would be false, and 73 < 74 would be true. Using anyone's height - h - that means h < 74 is true.

Put the pieces together, and we have 44 ≤ h < 74 (choice B).
