Answer:
$30.32
Step-by-step explanation:
381.7 ÷ 54 is used to find how many gallons you need but we know it won't be exact so we will round up the numbers.
382 ÷ 54 = 7
The answer isn't exactly 7 but in this situation, all you need to know is that it is over 7 since if the gasoline takes more than 7 gallons, you need to buy 8.
3.79 x 8 = 30.32

Answer:
A worked 20 hours and B worked 15 hours.
Step-by-step explanation:
Given:
Mechanic A hourly rate = $55
Mechanic B hourly rate = $45
Total charged = $1775
Let's assume Mechanic A worked 'A' amount of hours and Mechanic B worked 'B' amount of hours, then
Step 1:
First equation: A + B = 35
Second equation: 55xA + 45xB = 1775
Step 2:
First equation can be written as: A = 35 - B
Step 3: Replace value of A in second equation
Second equation: 55x(35-B) + 45B = 1775
: 1925 - 55B + 45B = 1775
: (1925 - 1775 )/10 = B
: B = 15 hours
A worked = 35 - 15
= 20 hours
Answer:
3qr - 6q²

= 3qr - 6q²
Answer:
4.) Choice B
&
5.) Choice A
Step-by-step explanation:
<em><u>Question 4:</u></em>
First you have to solve for y to get slope intercept form.
The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.
<em><u>Question 5:</u></em>
For this one I we will use this formula 
I will choose the easy pairs to plug it in 
The slope is a fraction again but you can convert it and that'll be Choice A.
