Suppose q is the midpoint of pr. use the information to find the missing value. pr = 9x-31 and qr=43; find x

Suppose Q is the midpoint of PR and PR = 9x-31 and QR=43, then the value of x will be 13

The midpoint of a line is the point that bisects or divides the line into two equal parts.

Hence suppose Q is the midpoint of PR, then:

PQ + QR = PR .... 1

and PQ = QR ...... 2

Substitute equation 2 into 1:

QR + QR = PR

2QR = PR

Given that:

PR = 9x-31 and QR=43, then;

2(43) = 9x - 31

86 = 9x - 31

Swap

9x - 31 = 86

Add 31 to both sides

9x - 31 + 31 = 86 + 31

9x = 117

Divide both sides by 9

Hence the value of x is 13

x = 13

Step-by-step explanation:

If Q is the midpoint of PR...then

PR = 2QR...since QR is half the length of PR

;9x - 31 = 86

;9x = 86 + 31

;9x = 117

Hence x = 117/9 = 13

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
