Please answer!!!!!! this math question?

Question

9(5+t) - 6(t + 3)

4(r + 8) -5(2r - 1)

- (m + 3) - 2(m + 3)

a[2 + b(2 + c)]

7b[8 + 6(b - 1)]

- [ -5(y + 2z) - 3z]

if y=3x-10, what is an expression for y/3?

Answer 1

9(5+t) - 6(t + 3) = 45+9t -6t -18

3t+27

4(r + 8) -5(2r - 1) (done the same as first)

- (m + 3) - 2(m + 3) distribute 2 and remove parens

- m - 3 - 2m -6

-3m - 9

the rest are done the same, just remember to do what's in the parens first and if you have a neg outside the parens, you need to change signs of what's inside.

Jordan gave you the answer for the last one.

Answer 2

1. 45 + 9t - 6t +18 = 63 - 3t

2. 4r + 32 - 10r - 5 = - 6r -27

3. -m -3 -2m -3 = - 3m -6

4. a (2 + 2b +bc) = 2a + 2ab + abc

5. 7b(8 + 6b - 6) = 56b + 42b<2> - 42b

6.- (- 5y - 10z -3z) = 5y +10z + 3z = 5y + 13y

y = 3x - 10

y/3 =(3x - 10) : 3

y/3 = (3x - 10)/3

Like this??

Sorry if don't..

Do you 7grd class.

Because it's question looks like 7grd agebra

good luck

Answer 3

y=3x-10

y+10=3x

(y/3)+(10/3)=x

y/3=x-(10/3)

Answer 4

Nice introduction, by the way

if y=3x-10, what is an expression for y/3?

I would say: y/3 = x -(10/3)

now my turn to ask: Who is smart, hey?   mmmm?

do I hear cheers?

Answer 5

(3x-10)/3

Answer 6

I have no idea what you are trying to write the first 6 lines of your question?

if y=3x-10 then y/3=x-(10/3)

???????????????

you need to learn to ask your specific question better, because I don't think I have answered it

Answer 7

t=8.4

Answer 8

+10/3 ?

That's really confusing :| Sorry.
