Answer: y+b/a=x
Step-by-step explanation:
add b to both sides of the equation
you should get y+b=ax
then divide a by both sides
you should get y+b/a=x
First, let's make 1/2 and 3/7 have the same denominator to make it easier to see. We know that there Least Common Multiple (LCM) is 14.
1/2=7/14
3/7=6/14
Wait a second... 3/7 is less than 1/2. This means that Winnie's statement is false because it is impossible that after adding more flour, she actually has less flour than what she started with.
Hope this helps! :)

So, we have to divide the total amount of the profit they made by the cost per car wash. This is because we have to find the unit rate. So, the problem would be $853 divided by $5. Now the answer would be 170.6, but if you round the answer, it would be approximately 170 cars. We have to round, because 0.6 is NOT a full car, and we need to know how MANY CARS were washed. We wouldn't do anything with the $12 they spent, because the problem does NOT state anything about the amount of cash they have AFTER the supplies were bought.
