(3 * x) - 4 is the expression.
Answer:
13 is your answer
Step-by-step explanation:
x - 8.1 = 5.3
+8.1 +8.1 Add 8.1 to both sides
x = 13.4
Which if you want the whole number i'd be 13, Because if your rounding the 3, 4 won't bump the 3 up any because 4 isn't greater than 5.
Hope my answer has helped you!
X= 6y
x + y = 525
solving these two equations
6y+y = 525
y = 75
x = 6*75=450
Total revenue = 450 * .03+ 75 * .05
= 17.25
(9y+y) + (6+3)
The answer is 10y+9
