If PR = 4x – 2 and RS = 3x – 5, which expression represents PS? x – 7
x – 3
7x – 7
7x + 3

Step-by-step explanation:

Given

Straight Line, PS

Such that

Required

Find PS

From the attachment above, it can be seen that RS is a continuation of PS;

This implies that

Substitute and

Collect like terms

Hence, the length of PS is

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000
