The answer is <span>a. x=10, y=-36
</span>
We have two equations.
Let's rearrange one of them:
<span>6x + y = 24
y = 24 - 6x

Now, write those two equations together:
y = 24 - 6x
3x + y/3 = 18

Substitute y in the second equation and solve it for x:
3x + (24 - 6x)/3 = 18
3x + 24/3 - 6x/3 = 18
3x + 8 - 2x = 18
3x - 2x = 18 - 8
<u>x = 10</u>

Now, using the first equation calculate y:
</span>y = 24 - 6x
y = 24 - 6 * 10
y = 24 - 60 
<u>y = -36</u>

Naddik [55]

Answer:

<h2><u><em>6. </em></u></h2><h2><u><em>   a. 11 and 2/3 yds. squared</em></u></h2><h2 /><h2><u><em>   b. Yes, the volume of the shed is 11 and 1/3 yards squared and what she's trying to put into it is only 10 yards squared, if put in properly, it will be able to fit.</em></u></h2><h2 /><h2><u><em>7. 1,110 in. squared</em></u></h2>

Step-by-step explanation:

6.

a.

(10/3)*(14/9)*(9/4)

= 11 2/3

b.

Yes, because the volume of the shed is about 11.67 yards long, the 10 yards of wood will fit in the shed.

7.

For this one, we have to break it into two pieces.

(I made them into a small box and and big box)

The measurements of the small box are 7*5*6.

The measurements of the big box are 20*5*9.

Using this information, we can make the following equation and solve it quickly.

(7*5*6) + (20*5*9)

(210) + (900)

1,110

Thus, the volume of this box is 1,110 in. ^2
