Parallelogram JKLM is shown. If KR=X+7, KM = 3x - 5. and JL = 4x - 10.

Lorico [155]

Answer:

Step-by-step explanation:

In a parallelogram, this one in particular:

KR = RM

JR = RL

We are looking in the end for the length of JR, but that means that we need to solve for x somehow to plug in the expression for JL, and then split that in half. Here's how we're going to go about it. I know that

KM = KR + RM, but since KR and RM are the same length, the equation becomes

KM = 2KR. Filling that in with the expressions I'm given for KM and KR:

3x - 5 = 2(x + 7) and

3x - 5 = 2x + 14 and

x = 19. Now I can find the length of JL:

JL = 4x - 10 so

JL = 4(19) - 10 and

JL = 66

Knowing that JR = RL and JL is 66 units long, JR = RL = 33 units each.

The sum of 3 times a number and 4 is between -8 and 10. Define a variable, write an inequality, and solve the problem.

hoa [83]

let the number be x

-8<3x+4<10

-12<3x<10

-4<x<10/3

Convert to degrees (pie over 2) pie —— 2

Answer:

90°

Step-by-step explanation:

$(\pi /2) * 180 = 90$

Whenever you are required to transfer from Radians to Degrees, simply multiply the Numerator by 180° (180). Treat the $\pi$ as a variable such as x and y, and divide by the numerator.
