Step-by-step explanation:
–6(x + 5) + 3 = –2(x + 4) – 4x
–6x – 30 + 3 = –2x –8 – 4x
–6x –27 = –6x –8
–6x + 6x = –8 + 27
0 = 19

Answer:
100
Step-by-step explanation:
10 x 10 = 100
Step-by-step explanation:
1. if to evaluate the given experssion, then
7⁶(7²-7+1)=7⁶*43.
2. if to divide this evaluated expression by 43, then
7⁶*43/43=7⁶.
First you have to figure out the length of the track:

r is the half of the diameter:
200ft : 2 = 100ft

= 200

≈
628,31
The athlete has to run ca. 5280ft for one mile:
5280 : 628,31≈8,4
The athlete has to run 8,4 laps
