5(x+2)=6x+3x-14 please solve
zavuch27 [327]

Answer:

5(x+2)=6x+3x−14

Step 1: Simplify both sides of the equation.

5(x+2)=6x+3x−14

(5)(x)+(5)(2)=6x+3x+−14(Distribute)

5x+10=6x+3x+−14

5x+10=(6x+3x)+(−14)(Combine Like Terms)

5x+10=9x+−14

5x+10=9x−14

Step 2: Subtract 9x from both sides.

5x+10−9x=9x−14−9x

−4x+10=−14

Step 3: Subtract 10 from both sides.

−4x+10−10=−14−10

−4x=−24

Step 4: Divide both sides by -4.

−4x

−4

=

−24

−4

So you know that 1 cubic foot is equal to 80 pounds. So, the first point would be (1,80). 
You can find the other points by multiply 80 by a number, and when I did that, I got (2,160) and (3,240) too.

I hope this helps :)

Can someone help please ??
adell [148]

Answer:

x=40

Step-by-step explanation:

In the picture, it seems that angles BHC, CHD, and DHE form a line, 180 degrees. So to solve, set up an equation:

(2x+5)+55+40=180

Take off the parentheses and solve.

Subtract 5, 55 and 40 from both sides, or add them together, then subtract.

5+55+40=100

You get:

2x=80

Divide both sides by 2

You get:

<h3>[x=40]</h3><h3></h3>

I hope this helps!
