Answer 1

1.-2v-7=-23 ---> correct
A.)15
B.)8***
C.)-8
D.)-15

4.-2(m-30)=-6m ----> no
A.)-15
B.)-13
C.)-8***
D.)8

-2m + 60 = -6m
4m = -60
m = -15

5.3n+2=8+2n ----- no
A.)3
B.)4***
C.)5
D.)6 <-----

6.Simplify the expression. -----no
-6-7(c+10)
A.)64-7c
B.)-76-7c
C.)4-13c
D.)-16-13c***

-6 - 7c - 70
= -67 - 7c

7.Solve the Equation. ----no
6(x-2)=36
A.)-8***
B.)-4
C.)4
D.)8

6x-12=36
6x = 48
x = 8

8.Solve the inequality. ------- no
p+4<-24
A.)p<-20***
B.)p<18
C.)p<-28
D.)p<20

p < -28

10.-8x>-64 ------ no
A.)x<8
B.)x>8
C.)x<-72
D.)x>72***

-8x > -64 , divide by -8, reverse sign
x < 8


Looks like somebody has a lot of work ahead of them
