Answer:
<u>The correct answer is A. x = - 9</u>
Step-by-step explanation:
Let's solve the equation:
5x + 8 − 3x = −10
5x - 3x = - 10 - 8
2x = - 18
<u>x = - 9 (Dividing by 2 at both sides of the equation)</u>
Now let's prove the answer is correct, replacing x with - 9.
5x + 8 − 3x = −10
5 (-9) + 8 - 3 (-9) = - 10
-45 +8 - 27 = - 10
-45 + 35 = - 10
-10 = - 10
<u>It has proven the value of x = - 9 is correct</u>
<u>The correct answer is A. x = - 9</u>

Answer:
36
Step-by-step explanation:
The equation for Ronny's total sales can be written as ...
450 +5x = 630 . . . . . where x is the number of additional mugs to be sold
5x = 180 . . . . . . . subtract 450
x = 36 . . . . . divide by 5
Ronny needs to sell 36 more coffee mugs to reach his sales goal.
You follow the same steps as you would normally, but you can count how many units down it is, instead of how far up.
