What is the solution to this equation 4x + 2 ( x + 6 ) = 36
Margaret [11]

The answer is A. x=4.


Start off by distributing the parentheses into the equation.

4x+2(x+6)=36

4x+2x+12=26


Combine like terms.

4x+2x=6x

6x+12=36


Now solve the equation as normal. Begin by subtracting 12 from both sides to isolate the variable.

6x+12=36

-12 -12

---------------

6x = 24


Divide 6 on both sides to find x.

6x=24

---- -----

6 6

x=4


The solution to the equation is 4.

Explain how to divide 3/4 ÷ 3/8 by using reciprocal of 3/8​
sertanlavr [38]

The reciprocal of 3/8 would be 8/3 (basically reversing the numbers).

When dividing fractions, you can just multiply the first fraction by the reciprocal of the second fraction instead of dividing by the second fraction.

3/4 ÷ 3/8

= 3/4 × 8/3

Simplifying gives us the final answer:

= 2

Let me know if you need any clarifications, thanks!

Write an equation of the line with the given properties. Your answer should be written in standard form.
Vanyuwa [196]

Given:

The slope of the line is m=0.

The line passes through the point P(-9,-3).

To find:

The equation of the line in standard form.

Solution:

Standard form of a line is:

Ax+By=C

The slope intercept form of the line is

y-y_1=m(x-x_1)

Where, m is the slope and (x_1,y_1) is the point on the line.

It is given that the slope of the line is 3 and it passes through the point (-9,-3), so the equation of the line is

y-(-3)=0(x-(-9))

y+3=0

y=-3

Therefore, the standard form of the given line is y=-3.
