4 0

Answer:

Step-by-step explanation:

1.) Apply the distributive law

5x + 5 * 2

2.) Multiply the numbers

5 * 2 = 10 is equivalent to 5x + 10

3.) Group like terms

5x - 3 + 10

4.) Add/subtract the numbers

-3 + 10 = 7 is equivalent to 5x + 7

6.3r < -45.36 which graph shows the correct soultion

skelet666 [1.2K]

6.3 r < -45.36

Here first we have to solve for r and for that we need to get rid of 6.3 .

To get rid of 6.3, we divide both sides by 6.3 that is

r < -7.2

So the solution is all the values which are less then -7.2

And for graph, we put a blank circle or a parenthesis that is () on -7.2 and extend a line to the left side since the inequality is less then .

Angle 1 is vertical to Angle 2. Angle 1 =94, Angle 2 = 2(x-13), Find the value of x.

rodikova [14]

Answer:

x= 56

Step-by-step explanation:

86+94= 180 which if supplementary angles have to equal 180°

I don't know if you can tell but what's in red means distribute

then I added 26 on both sides with like terms

on the left side 86+26=112 and right side is left with 2x

then divide both sides by 2 to leave x by itself

112/2= 56 and 2x/2=x

so 56=x
