Yesterday, the store made $10,500 in sales
First combine like terms (-9n-3n=-12n)
Then, subtract 6n on both sides (to get rid of the 6n) = -18n
Then, add 8 to both sides (does not matter) = 0
Finally divide (answer is 0)
Temperature will be plotted on the y-axis
Answer:
9
Step-by-step explanation:
2w+6=-2w+42
4w+6=42
4w=36
w=9
4x + 89.95 = 628.35 <== ur equation
4x = 628.35 - 89.95
4x = 538.40
x = 538.40 / 4
x = 134.60 <== the cost for each cavity filling
