Answer:
8%
Step-by-step explanation:
Tax equals the original amount times the tax rate
We can find the tax by taking the amount he paid minus the original amount
tax = 156.6 - 145
tax = 11.6
tax = original amount * tax rate
11.6 = 145 * tax rate
Divide each side by 145
11.6/145 = 145/145 * tax rate
.08 = tax rate
To change this to percent, multiply by 100%
.08*100% = 8%
Answer:
<em>x = 11.83°</em>
Step-by-step explanation:
<u>Equations</u>
The figure shows two parallel lines crossed by a line. We have completed the figure with another variable y. Please see the attached image.
Angles y and 4x+28 are linear, thus their sum is 180°:
y + 4x + 28 = 180
Angles y and 8x + 10 are corresponding, thus
y = 8x + 10
Substituting:
8x + 10 + 4x + 28 = 180
Simplifying:
12x + 38 = 180
Subtracting 38:
12x = 142
Dividing by 12
x = 11.83°
