(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.
180-x-180+2x=53
x=53
Final answer: The angle is 53 degrees.

Answer: y=-3x+29
Step-by-step explanation:
First put in y-intercept form to find the slope

Slope of the 1st equation is 1/3- the slope of the line perpendicular is the opposite reciprocal, so in the case it is -3
Use the point and the new slope to write the new equation in point slope format

Answer:
4 miles per hour
Step-by-step explanation:
We can divide 45 minutes by 3 to get 15 minutes:
So that is 1 mile in 15 mins
Then we multiply both sides by 4 to get 60 mins:
4 miles in 60 mins
So his rate was 4 miles per hour
The difference between the 2 different temperatures.
The key word difference refers to subtraction.
So 18 - ( - 13 )
Subtracting a negative is the same as adding the positive.
So 18 + 13
Solve the statement to get:
