Answer:
x=7 so there is one solution
Step-by-step explanation:
5x-(7x-1)=-3x+8
Distribute the minus sign
5x -7x +1 = -3x+8
Combine like terms
-2x +1 = -3x+8
Add 3x to each side
-2x+3x+1 = -3x+3x+8
x+1 = 8
Subtract 1 from each side
x+1-1=8-1
x=7
Write out all the solutions from 1 to 10 and add them together
(1^2+3(1)-2)=2
(2^2+3(2)-2)=8
" = 16
" = 32
" = 38
" = 52
" = 68
" = 86
" = 106
" = 128
Add them together: 530
Hope I helped :)
Answer:
I'm pretty sure it's the last one that is incorrect
Step-by-step explanation:
Answer: 42
Step-by-step explanation:
x/3-4=10
x/3=10+4
