Answer:
2 over 3
Step-by-step explanation:
The labor fee is $13.55 and each quart of oil is $2.25
Step-by-step explanation:
Let,
x be the amount of each quart of oil
y be the amount of labor fee
According to given statement;
5x+y=24.80 Eqn 1
7x+y=29.30 Eqn 2
Subtracting Eqn 1 from Eqn 2
![(7x+y)-(5x+y)=29.30-24.80\\7x+y-5x-y=4.50\\2x=4.50](https://tex.z-dn.net/?f=%287x%2By%29-%285x%2By%29%3D29.30-24.80%5C%5C7x%2By-5x-y%3D4.50%5C%5C2x%3D4.50)
Dividing both sides by 2
![\frac{2x}{2}=\frac{4.50}{2}\\x=2.25](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B4.50%7D%7B2%7D%5C%5Cx%3D2.25)
Putting x=2.25 in Eqn 1
![5(2.25)+y=24.80\\11.25+y=24.80\\y=24.80-11.25\\y=13.55](https://tex.z-dn.net/?f=5%282.25%29%2By%3D24.80%5C%5C11.25%2By%3D24.80%5C%5Cy%3D24.80-11.25%5C%5Cy%3D13.55)
The labor fee is $13.55 and each quart of oil is $2.25

Answer:
The jacket costs $45
Step-by-step explanation:
In order to find this, notice that the price of the sale represents 80% of the total cost. This is because we took 20% away with the sale. Now we can find the overall amount by dividing the sale cost by the amount it represents.
$36 / 80% = $45
A) Measure of Angle L is 67.5. Angle F & Angle L are alternate interior angles.
b) Measure of Angle E is 112.5, because we know that F and H are vertical angles, so therefore they’re congruent. We also know H and E are adjacent, so H + E = 180.
c) Angles E and K are alternate exterior angles. Measure of Angle K is 112.5.
d) Measure of Angle H is 67.5, because we know that Angle F, which is vertical to Angle H, is 67.5. Vertical angles are congruent.
e) Measure of Angle I is 112.5, because Angle I and Angle K are vertical angles.
f) They’re corresponding angles.
