Answer:
6x+y=-8 because it will be y=-6x-8 having same slope with the line given
Making 10 chairs would take Marjorie and Blaine<u> </u><u>21 hours and 40 minutes</u>.
<h3>How long does it take to make 10 chairs?</h3>
The total time it takes Marjorie and Blaine to perform their respective tasks in building a chair is multiplied by 10 chairs, respectively. This time is known as their speed.
The resulting figures are summed to get the total time.
<h3>Data and Calculations:</h3>
The total time it takes Marjorie to build a chair is 15 hours (1.5 hours x 10)
The total time it takes Baline to sew cushions per chair is 400 minutes (40 x 10) or 6 hours and 40 minutes.
Therefore, the total time to build 10 chairs is 21 hours, 40 minutes (15 hours + 6 hours and 40 minutes).
Thus, making 10 chairs would take Marjorie and Blaine <u>21 hours and 40 minutes</u>.

Answer:
![11.79\ euros](https://tex.z-dn.net/?f=11.79%5C%20euros)
Step-by-step explanation:
<u><em>The complete question is</em></u>
Suppose that a new fuel-efficient European car travels an average of 28 kilometers on 1 liter of gasoline. If gasoline costs 1.50 euros per liter, how much will it cost to drive 220 kilometers ?
step 1
using proportion
Find out the number of liters of gasoline needed for 220 kilometers
so
![\frac{28}{1}\ \frac{Km}{L}=\frac{220}{x}\ \frac{Km}{L}\\\\x=220/28\\\\x=7.86\ L](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B1%7D%5C%20%5Cfrac%7BKm%7D%7BL%7D%3D%5Cfrac%7B220%7D%7Bx%7D%5C%20%5Cfrac%7BKm%7D%7BL%7D%5C%5C%5C%5Cx%3D220%2F28%5C%5C%5C%5Cx%3D7.86%5C%20L)
step 2
Find the cost to drive 220 kilometers
Multiply the cost of one liter of gasoline by the total liters of gasoline needed to travel 220 Km
so
![1.50(7.86)=11.79\ euros](https://tex.z-dn.net/?f=1.50%287.86%29%3D11.79%5C%20euros)

Answer:
9d^2/(2d + 4).
Step-by-step explanation:
18d^2 / (4d + 8)
First factorise the denominator:
= 18d^2 / 4(d + 2)
The GCF of 18 and 4 is 2 so this simplifies to:
9d^2/2(d + 2)
= 9d^2/(2d+ 4).
