Clean up the equation with x first and x=12.
Substitute this value in to the other equation to solve for y.
You should get a solution of (12,-8)
Answer:
-220
Step-by-step explanation:
There were 125 bags to start with.
Explanation: Let x be the number of lunches to start with.
96 were given out, so x - 96 remain.
As we have 29 left, we know that x - 96 = 29
So x = 29 + 96 = 125
Answer:
C. the subtraction property of equality
Step-by-step explanation:
12-x = 7x + 32
Step - 1: -x = 7x + 20
In that case, we just swap 12 from the left side to right side, and then we subtract 12 from 32 which is on the right side. Therefore, we do not multiply, divide or add anything. So, the option "C" is correct.
Step 2: -8x = 20
In that case, we again subtract 12 by interchanging the side. Moreover, we change the side of 7x to deduct it from -x.
Therefore, in both the cases, we use the subtract property of equality.
Sandy would probably take just as long as her mother because it says their mother takes 5 hours if decorating the house alone so if sandy is doing it alone it would also probably take her 5 hours as well. If this is wrong I’m sorry.
