Answer:
vertical angles are equal:
< (1) = < (2) (in fact they are congruent angles)
so, if measure of < 1 is 63° and measure of < 2 is 4x-9°, than
4x-9=63° ...solve for x
4x=63%2B9°
4x=72°
x=72%2F4°
x=18°
if x=18°, than < 2 is 4x-9=4%2A18-9=72-9=63°...it proves that < (1) = < (2) are congruent angles

12,000, because 11,900>11,500, so you round it up to 12,000
(a) Sorry. I don't know the answer.
(b) The angle will be 75 degrees. It is a corresponding angle to the 75 degree angle.
(c) The angle is 105 degrees. This angle along with the 75 degree angle make a straight line, 180 - 75 = 105 degrees.
-1
If you divide the coefficients of x^4 - 2 (which are 1, 0, 0, 0, -2) by -1 (from x +1), you will get a remainder of 1
The expression represents the number of gallons used is m/22.
Given
Nikki can drive her car 22 miles on each gallon of gasoline.
<h3>What is the unit rate?</h3>
A rate is a ratio that is used for comparing two different kinds of quantities which have different units.
To find the number of gallons used we will divide the total distance traveled by distance traveled in one gallon.
Therefore,
If Nikki drives m miles, the expression represents the number of gallons used is;
Hence, the expression represents the number of gallons used is m/22.
