Answer 18

Thank you @surjithayer

Answer 19

Can you help me understand how to solve them? the ones I got wrong

@surjithayer

Answer 20

2.2
if z=9
then 15-9=6
which is correct.

Answer 21

for 4.4
\[m=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 22

5. 5
slope of line
ax+by=c is
\[m=\frac{ -a }{ b }\]

Answer 23

wow that was easy xD I feel so dumb

Answer 24

For number four I got -5/4 is that correct?

Answer 25

6.6
if s=6
\[-3\left| s \right|=-3\left| 6 \right|=-3*6=-18 \neq 18\]
if s=-6
\[-3\left| s \right|=-3\left| -6 \right|=-3*6=-18\neq 18\]
so no solution.

Answer 26

2x+6-6x=30
-4x=30-6
-4x=24
x=24/(-4)=-6

Answer 27

So if you plug in the the numbers for number 5 it would be 15= -5/3 right?

Answer 28

82.5+94.7+87.9+x=4*90
265 .1+x=360
x=360-265.1=94.9+95(rounded off)
x=95%

Answer 29

wow now I understand that problem, it took me a while to understand it.

Answer 30

@surjithayer

Answer 31

11.11
2.1 x+4.09=6.98 x+1.73
2.10 x-6.98x=1.73-4.09
-4.88 x=-2.36
x=?

Answer 32

12.12 incorrect.
z=2 x+4 y
4 y=z-2 x
\[y=\frac{ 1 }{ 4 }\left( z-2x \right)\]

Answer 33

correction it is 4x +2y so make necessary changes.

Answer 34

For 11 you would have to divide -2.36/-4.88 right?

Answer 35

11 is -0.5? @surjithayer

Answer 36

I don't understand what you mean for number 5 @surjithayer

Answer 37

@Sparklestaraa

Answer 38

Can yo help me with 4 and 5 please? @pooja195

Answer 39

\[x=\frac{ -2.36 }{ 4.88 }=\frac{ 59 }{ 122 }\]
=0.5(nearly)

Answer 40

\[m=\frac{ -2-3 }{ 5-1 }=-\frac{ 5 }{ 4 }\]

Answer 41
