Answer:
<h2>
8(4 + n) = 112</h2>
Step-by-step explanation:
Let's start by reading the problem since it maybe is a bit confusing at first.
The product of 8
Now we know that it starts with 8 multiplied by another number. We do not know that number yet, so let's put 8 * () and fill in the parentheses later.
So far, our equation is:
8()
.. And the sum of 4 and a number
So, 4 + n
We can enter that into our equation
8(4+n)
The next line says "..Is 112"
So, the solution to our equation is 112
Our equation becomes:
8(4+n)=112
x + 6 = 3x - 18
- x - x
6 = 2x - 18
+ 18 + 18
24 = 2x
2 2
12 = x
The answer is C.
Answer:
See the screenshot
Step-by-step explanation:
Determine two points by substituting values for x and solving for y. Then plot the points and draw a dashed straight line through the points to indicate that they are not part of the inequality. Shade in the area above the line.

Andrew (4) x 2 = 8 + 4 = 12 (Tom)
Andrew (4) x 5 = 20 - 8 = 12 (Sara)
