Answer:
x = 3
Step-by-step explanation:
4(2-x)+13=2x+3
distribute the 4.
8 - 4x + 13 = 2x + 3
combine like terms.
21 - 4x = 2x + 3
18 = 6x
divide by 6.
x = 3
check.
4(2 - 3) + 13 = 2(3) + 3
4(-1) + 13 = 6 + 3
-4 + 13 = 9
9 = 9
correct!
Answer:
2/3
Step-by-step explanation:
51, 60, 63, and 65 are greater than 50.
Answer:
12x+9
Step-by-step explanation:
To find the perimeter, add all the sides
3x+8 + 4x-1 + 5x +2
Combine like terms
3x+4x+5x +8-1 +2
12x+9
Answer:
They have the same end results
<em><u></u></em>
Step-by-step explanation:
Given
The missing equations are:


Required
Make a generalization about the equations
First, we solve both equations.
(1)



(2)


From the solutions to the above equations, we can see that both equations have the same end result;
i.e.

Hence;
A generalization can be: <em><u>"they have the same end results"</u></em>
