Answer:

x=-28

Step-by-step explanation:

-3(x-1)+8(x-3)=6x+7

1) Distribute -3 to x and -1:

-3x+3

2) Distribute 8 to x and -3:

-3x+3+8x-24=6x+7

3) Combine alike terms:

5x-21=6x+7

4) Subtract 5x from both sides:

-21=x+7

5) Subtract 7 from both sides:

x=-28

Footnotes:

The <u>Distributive</u> property says a(b+c)=ab+ac

Can someone please help me? I don't understand this problem. How would they be the same???
musickatia [10]
Area of rectangle = 15 x 8
                           =120

area of parallelogram = 8 x 15 
                               =120
so, they have the same area, because the length of a rectangle is the same as the height of a parallelogram and also for the base.

The sum of a number times 8 and 21 is less than -16.
vodka [1.7K]

Hello.

First of all, let the number be t.

8 times t can be written like this:

\mathrm{8t}

Notice that the number is before the variable and the times sign (×) is not there.

We can write it as 8×t, but we usually write it as 8t.

The sum of means we add:

8t+21

Now, "less than" is "<" :

\mathrm{8t+21 < -16}

Therefore, the answer is

\mathrm{8t+21 < -16}

I hope it helps.

Have a nice day.
