Answer:
28
Step-by-step explanation:
2x + 3x + 40 =180
5x= 180 - 140
5x=140
x= 28
Answer:
39
Step-by-step explanation:
2x5=10
10+3=13
13x3=39
Answer: Her refund would be $5,681.20.
The problem says that Laura paid the estimate above, which is 28%.
0.28 x 134350 = 37618
However, she had some deductions.
134350 - 4000 - 12200 - 4090 = 114060
So, to find the tax on this amount, we multiply it again by 0.28.
0.28 x 114060 = 31936.8
The amount of the refund will be the difference.
37618 - 31936.8 = 5681.2
Answer:
Step-by-step explanation:
An equation of a line is given 
, where m is the gradient or 
The rise indicates the change in value of y (vertical change in the graph).
The run indicates the change in value of x (horizontal change in the graph).
Let point 1 of the graph be (x,y) = (0,-34) and point 2 be (x,y) = (20,0).
Substitute point 1 into the graph to get the constant c.
∴ The equation of the line is,
Answer:
From the above we can roughly for an equation which is:
58.50 = Bill - (10% x Bill)
58.5 = Bill - (1/10 x Bill)
58.5 = 9/10 x Bill (Divide both sides by 9/10)
We get:
Bill = 58.5 / (9/10)
Bill = 65
Original bill is $65.
