Answer: (-9,6)

Step-by-step explanation:

3x+2y=-15

2x=-18

First solve for x in second equation

2x=-18

2x/2=-18/2

X= -9

Now substitute your x into first equation to find y

3(-9)+2y= -15

-27+2y=-15

2y= -15+27

2y= 12

2y/2=12/2

Y= 6

Use the table at the right.<br> a. What is the approximate volume of the small truck?

irina [24]

Volume of the small truck = 554.54 cubic ft

Solution:

Given data:

Length of the small truck = $11\frac{1}{13}$ ft

Width of the small truck = $7\frac{5}{12}$ ft

Height of the small truck = $6\frac{3}{4}$ ft

Volume of the small truck = length × width × height

$$=11\frac{1}{13}\times7\frac{5}{12}\times 6\frac{3}{4}$

Let us change the mixed fraction into improper fraction.

$$=\frac{11\times 13 + 1}{13}\times\frac{7 \times 12 + 5}{12}\times \frac{6 \times 4 + 3}{4}$

$$=\frac{144}{13}\times\frac{89}{12}\times \frac{27}{4}$

$$=\frac{7209}{13}$

= 554. 54 cubic ft

Volume of the small truck = 554.54 cubic ft

There are 15,000 students attending the community college. Find the percent of a students that attend classes in the evening if

lubasha [3.4K]

Answer:

25% of students attend classes in the evening.

Step-by-step explanation:

The proportion of evening students is the number of evening students divided by the total number of students.

The percentage is the proportion multiplied by 100.

We have that:

In total, there are 15000 students.

3750 are evening students

3750/15000 = 0.25

0.25*100 = 25%

25% of students attend classes in the evening.
