See the attached picture for 2 options for question 1 and 2 depending on how the fractions are written.
Question #3:
17 = -13 - 8x
Add 13 to each side:
30 = -8x
Divide both sides by -8:
X = 30 / -8
X = -3 3/4
Answer: 45
Explanation: two angles that form a Line always equal 180 degrees, so we start with the equation 180-u+47, which is the measure of the missing interior angle measure. All of the angles inside of a triangle also equal 180 degrees, so we can set up this equation to find U:
u-18+u+(180-u+47)=180
We can start to simplify by first simplifying what’s inside the parenthesis:
u-18+u+153-u=180
Then you solve the equation to get
U=45 degrees
Present value of loan, P = 19541
monthly interest rate, i = 8.3%/12
repayment period = 6 years = 72 months
Monthly payment,

The correct answer is y=0.45x
there are 3600 seconds per hour
5280 feet per mile
1 foot per second = 3600/5280 = 0.681818 Miles per Hour
60 seconds per minute
so 1500/60 = 25 feet per second
25 x 0.681818 = 17.05 miles per hour
