Answer:

- 1 4/5

Step-by-step explanation:

-1 1/5 + - 3/5

Since the signs are the same, we add and take the sign

1 1/5 + 3/5

1 4/5

The sign is negative

- 1 4/5

On the number line start at - 1 1/5 and go to the left 3/5( since the sign is negative) you will end up at - 1 4/5

I NEED THIS ASAP please. can someone please answer this question i put the picture its on Simplify Expressions im giving 15 poin

kakasveta [241]

Answer:

in step 4

Step-by-step explanation:

we have

$0.5(-12c+6)-3(c+4)+10(c-5)\\\\step1=-12c(0.5)+6(0.5)-3(c+4)+10(c-5)\\\\=-6c+3-3(c+4)+10(c-5)\\\\$

so step 1 is correct

step 2

$-6c+3-3(c+4)+10(c-5)\\\\=-6c+3+c(-3)+4(-3)+10(c-5)\\\\=-6c+3-3c-12+10(c-5)$

so step 2 is correct

step 3

$-6c+3-3c-12+10(c-5)\\\\=-6c+3-3c-12+c(10)-5(10)\\\\=-6c+3-3c-12+10c-50$

so step 3 is correct

step 4

$-6c+3-3c-12+10c-50\\\\=(-6c-3c+10c)+(3-12-50)\\\\=(-6-3+10)c+(-9-50)\\\\=(-9+10)c-59\\\\=c-59$

so step 4 is incorrect

=0.356+2(0.565)
=1.486$
9) $x(x+2)=8
x=2$
10) $x/(2x+3)=1/9
9x=2x+3
x=3/7$

Hope this helps
