Question

I tried them all ready I need help

Create an equvilant expression using the fewest number of terms

2.5-4x+7+6x

4. 2(x-14)+ 3(3x+5)

I can't figure it out can u show me how u get the answer plz and thank u

Ms. Sue
2.5-4x+7+6x =

2.5 + 7 - 4x + 6x =

9.5 + 2x

~~~~~~~~~~~~~~~~~~~~~~~~~~
4. 2(x-14)+ 3(3x+5)

Is 4 the number of the problem? Or is 4.2 part of the problem?


Rian
The number of the problem
Ms. Sue
Thanks.

Then 2 must be the number of your first problem.

2(x-14)+ 3(3x+5)

2x - 28 + 9x + 15

11x - 13

Rian
2 isn't in the problem either
Ms. Sue
I showed you how to do problem number 4.

Can you solve problem number 2 now?

Rian
No I can't , because two isn't part of the problem

In order to solve 5-4x+7+6x, you must first combine like terms.

-4x + 6x = -2x

Here's your next equation:

5+7-2x

Next, you add 5 and 7 together.

5 + 7 = 12

Finally, after you do that, you get the last equation:

12-2x

This is your final answer.

Hope this helps you for number 2!

I am anonymous, but here is what I said again:

"In order to solve 5-4x+7+6x, you must first combine like terms.

-4x + 6x = -2x

Here's your next equation:

5+7-2x

Next, you add 5 and 7 together.

5 + 7 = 12

12-2x

This is your final answer.

Hope this helps you for number 2!"

Need help on 4 more problem that is it I tried about 5 times each still got wrong

1) an architect built a model of a 220ft tall building . The model is 25inches tall and 10inches wide. How wide is the actual building , I know the answer is 88 but how do u get it.



1= -3y +19


h/6 - 11 = -22

10x-2(x -8) =14
Ms. Sue
What answers did you get for these problems?

Please show your work so that we can find where you went wrong.

Ms. Sue
By the way -- Brady's answer is not correct.

Brady
Oh Ms. Sue, is the mistake -2x? It's supposed to be a positive 2x.

If so, the final answer should have been:

12+2x

That's the only mistake that I noticed. I hate it when I do mistakes like that. It happens all the time for me.
Ms. Sue
:-) Mistakes happen to all of us. I'm glad I caught it.

Brady
Yeah, I'm glad you caught that mistake as well.

Back to your 4 problems Rian. - I can't help much with the first problem, but I know how to get the answers for the other three. However, I am just going to do 2 of those problems for you.

2nd problem:

1 = -3y + 19

(1 - 19) = -3y (+ 19 - 19)

-18 = -3y + 0

-18 = -3y

(-18/-3) = (-3y/-3)
6 = y

Now double-check:

1 = -3(6) + 19

1 = (-18) + 19

1 = 1

So, 6 is the answer for this one because you were supposed to solve for y.

3rd Problem:

h/6 - 11 = -22
h/6 (- 11 + 11) = (-22 + 11)
h/6 - 0 = -11
h/6 = -11
(h/6 * 6/1) = (-11*6)
h = -66

Now double-check:

(-66/6) - 11 = -22

(-11) - 11 = -22

-22 = -22

So, -66 is the answer to that problem because you were supposed to solve for h.

There you go, and hopefully you understand how to do the problems above. Now, try doing your 4th problem like the way I did it above. I hope this helps!

I really need help on the first one
Ms. Sue
Repost that question on Wednesday. Be sure to show what you've done to try and solve it.
