I have 4 questions 1. Suppose point T is between points R and V on a line. If RT = 63 units and RV = 131 units, then what is TV? 131 194 68 80

2.Given point P is between M and N. If MN = 26, MP = x + 4, and PN = 2x + 1, what is the value of x? x = 3 x = 7 x = 12.5 x = 22

3.Given M is the midpoint of HJ, HM = 4x - 12, and MJ = 3x + 9. What is the value of x?

4.If D is the midpoint of CE, DE = 2x + 4, and CE = 6x + 2, then what is CD?

Step-by-step explanation:

Solving (1):

Given

Required

Determine TV

To solve TV, we make use of the following formula;

Substitute values for RT and RV

Make TV the subject of formula

Solving (2):

Given

Required

FInd x

To solve x, we make use of the following formula;

Substitute values for MP, MN and NP

Collect Like Terms

Divide both sides by 3

Solving (3):

Given

Required

Find x

Since M is the midpoint;

This gives

Solving (4):

Given

Required

FInd CD

Since D is the midpoint;

and

Substitute CD for DE

Substitute values for CE and DE

Open Bracket

Collect Like Terms

Divide both sides by 2

Recall that;

So;

Substitute 2 for x
