Answer:

B. 24 inches by 30 inches

Step-by-step explanation:

Since the poser is similar to a rectangle measuring 8 in. by 10 in., we have to find which solution has the same proportions.

When simplified, 8/10 = 4/5. That is our proportion.

A) 2/2 does not equal 4/5

B) 24/30 (when simplified) = 4/5

B is our right answer because when 8 is multiplied by 3, you get 24 and when 10 is multiplied by 3 as well (both multiplied by the same number to keep the proportions the same) you will get 30.

Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of t

alex41 [277]

Answer:

$\angle MKJ = 34$

Step-by-step explanation:

Given

$\angle LKJ = 124$

Required

Find $\angle MKJ$

From the attachment:

The measure of $\angle MKJ$ is calculated using the following expression:

$\angle MKJ + \angle LKM = \angle LKJ$

Where

$\angle LKM = 90$ -- right-angled.

The expression becomes

$\angle MKJ + 90 = 124$

$\angle MKJ = 124 - 90$

$\angle MKJ = 34$

If K is the midpoint of JL, JK = 9x -1 and KL = 2x +27, find JL

Liula [17]

Answer:

JL = 70

Step-by-step explanation:

Since K is the midpoint of JL then JK = KL and

JL = JK + KL = 9x - 1 + 2x + 27 = 11x + 26

solve for x using JK = KL

9x - 1 = 2x + 27 ( subtract 2x from both sides )

7x - 1 = 27 ( add 1 to both sides )

7x = 28 ( divide both sides by 7 )

x = 4, hence

JL = 11x + 26 = (11 × 4 ) + 26 = 44 + 26 = 70

ILL GIVE BRAINELST PLZ HELP FAST!!!

Rasek [7]

Answer:

Hello. Let me explain.

Step-by-step explanation:

For the first question.

$m = \frac{y2 - y1}{x2 - x1 } = \frac{8 - ( - 6)}{ - 3 - 4} = \frac{14}{ - 7} = - 2$

For the second question.

$y - y0 = m(x - x0) \\ y + 6 = - 2(x - 4) \\ y = - 2x + 8 - 6 \\ y = - 2x + 2$

So b is +2

Hope you understand
