4x+7=35
4x=28
x=7
A corresponding solution of the matching equation is a fancier way of telling you to find the number that represents x
30% of the 30 marbles is nine and 9-30 = 21 so your answer is 21
I will assume that we are trying to find the slope between (-9,2) and (9, 2)
The slope's equation ⇒ 
<u>Let's set the variables</u>:
(x1, y1) --> (-9, 2)
(x2, y2) --> (9, 2)
<u>Now let's plug them in:</u>

<u>Thus the slope of the line is 0.</u>
Hope that helps!
The club can buy 5 computers with $3472
Step-by-step explanation:
The number of computers which can be bought from the given amount will be calculated by dividing the amount by price of one computer.
Given
Total amount = $3472
Price of one computer =$680
The number of computers will be:

As the number of an item cannot be in decimal it will be rounded off to 5.
