X - the rate charged by the first mechanic
y - the rate charged by the second mechanic
The sum of the two rates was $155.

The first mechanic worked for 10 hours, the second mechanic worked for 5 hours, and together they charged $1000.

Set 155-x and 200-2x equal to each other:

The rate charged by the first mechanic was $45, and the rate charged by the second mechanic was $110.
I think the answer is 1/16 ...not for sure tho
Answer:
Part 1: 100
Part 2: 29.19 (Rounded)
Part 3: 20.96 (Rounded)
Step-by-step explanation:
<u>Part 1</u>: Triangle Sum Theorem (All angles of a triangle add up to 180 degrees)
45 + 35 + A = 180
80 + A = 180
Move the constant to the other side
80 + A = 180
-80 -80
A = 80°
<u>Part 2:</u> Law of sines

Cross multiplication
sin(35)a = 16.7417318
Divide both sides by sin(35)
a = 29.18831866
<u>Part 3</u>: Law of cosines
= 439.2809039
Square root the answer
=20.95902917
To convert 45000 inches into miles first you have to find out how much is miles to inches then divide you should 0.4500
