Answer:
x= -4
Step-by-step explanation:
3=8x-5(3x+5)
distribute
3=8x-15x-25
combime like factors
28= -7x
divide 28/ -7
x= -4
The average score is 90.6
2x100=200
9x95= 855
10x90=900
80x3=240
1x70=70
Total. 2265
2265/25=90.6
Subtract 7 from 19 then divide the result by 3
19-7=3w
12=3w
12/3=w
4=w
W is 4
Answer:
-4y -12
Step-by-step explanation:
