Point A is the midpoint of side XZ and point B is the midpoint of side YZ. Triangle X Y Z is cut by line segment A B. Point A is
AveGali [126]

Answer:

<h3>B. 4units</h3>

Step-by-step explanation:

Find the diagram attached. The diagram is a similar triangle.

From the diagram, XZ/XY = CA/AB

Given XZ = 2x-2+2x-2 = 4x-4

XY =5x-7

CA = 2x-2

AB= x+1

On substituting this parameters into the formula to get x first

4x-4/5x-7 = 2x-2/x+1

cross multiply

(4x-4)(x+1) = 5x-7(2x-2)

open the parenthesis

4x²+4x-4x-4 = 10x²-10x-14x+14

4x²-4 = 10x²-24x+14

10x²-4x²-24x+14+4 = 0

6x²-24x+18 = 0

x²-4x+3 = 0

x²-3x-x+3 = 0

x(x-3)-1(x-3)  =0

(x-3)(x-1) = 0

x = 3 and 1

Next is to get length AX.

Given AX = 2x-2

Substitute x = 3 into the expression

AX = 2(3)-2

AX = 6-2

AX = 4 units

Hence the measure of length AX is 4 units

Hector works 12 hours per week at a part-time
iren [92.7K]

Answer:

b. $2.50

Step-by-step explanation:

Let us take a step by step approach by simplifying each sentence:

Sentence 1: Hector works 12 hours per week at a part-time  hours per week at a part-time job

Number of hours worked per week  = 12hours

Sentence 2:  His original pay rate was $8.00 per hour. but he recently received a raise of x dollars per hour

   Pay per hour is 8hr, a raise of x gives 8 + x

Sentence 3: New total wage  = 12(8+x)

Sentence 4: Amount earned last week  =  $126

  New total wage = Amount earned last week

               12(8 + x ) = 126

                 96 + 12x  = 126

                          12x  = 126 - 96

                           12x  = 30

                             x = $2.50

Amount of raise is $2.50
