5x-3
When parentheses are open you get 2x+5+3x-8
Because both parts with x are positive we add them together and get
5x+5-8
+5-8
Is the same as -3 because when you add 5 to -8 you are making the number greater
Hence you get 5x-3

Answer:

5x - 3

Step-by-step explanation:

Subtract the numbers

(2x+5) + (3x-8)  ---->  2x-3 +3x

Combine like terms

2x-3 + 3x ----> 5x - 3

Answer

5x - 3

done! :)

Two angles are complementary angles if the sum of their measure is 90 degrees. Angle A and angle B are complementary angles, and
Marta_Voda [28]
Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

We will be using simultaneous equations to solve this problem.

First we will establish the equations which we will be using as displayed below:

Equation No. 1 -

A + B = 90°

Equation No. 1 -

A = 2B + 12

To begin with, let's make ( A ) the subject in the first equation as displayed below:

Equation No. 1 -

A + B = 90

A = 90 - B

Next we will substitute the value of ( A ) from the first equation into the second equation and solve for ( B ) as displayed below:

Equation No. 2 -

A = 2B + 12

( 90 - B ) = 2B + 12

- B - 2B = 12 - 90

- 3B = - 78

B = - 78 / - 3

B = 26°

Then we will substitute the value of ( B ) from the second equation into the first equation to solve for ( A ) as displayed below:

A = 90 - B

A = 90 - ( 26 )

A = 64°

ANSWER:

Therefore, the answer is:

A = 64°

B = 26°

Write that down the equation for the lines that is the graphs are depicted below
erastovalidia [21]
  • A(1,2)

Find slope of line (m)

\\ \sf\longmapsto m=\dfrac{2-0}{1-0}

\\ \sf\longmapsto m=2

Putting in y=mx+b

\\ \sf\longmapsto y=mx+b

\\ \sf\longmapsto 2=2(1)+b

\\ \sf\longmapsto 2=2+b

\\ \sf\longmapsto b=2-2=0

Equation of the line

\\ \sf\longmapsto y=2x
