Answer:
4.11
Step-by-step explanation:
7(p-9)=-34.3
first you want to apply what is outside of the parenthesis to the inside of the parenthesis. After applying you would get
7p-63=34.3
Next you wanna get the variable to one side and the whole numbers to the other side. to do this you add 63 to each side, you end up with
7p=28.8. Then you want to get p by itself. In order for this to happen you divide each side by 7 to get p=4.114285714

Answer:
17
Step-by-step explanation:
Since angle KLJ~angle VWU are similar :
KL / WV = KJ/ UV
(25 / 20) = (4x - 23 / 2x + 2)
Cross multiply :
25(2x + 2) = 20(4x - 23)
50x + 50 = 80x - 460
50x - 80x = - 460 - 50
-30x = -510
x = 510 / 30
x = 17
