Hey there!

We can solve systems two ways - substitution and elimination. It seems in this case that elimination is going to be easier.

Let's begin by multiplying the top equation by 3, and the bottom equation by 4:

3(5x - 4y = -24)

15x - 12y = -72

4(4x + 3y = 18)

16x + 12y = 72

Next, we'll add the two equations together to get rid of, or eliminate, the y variable and solve for the x variable:

(15x - 12y = -72) + (16x + 12y = 72)

31x = 0

x = 0

Next, we'll plug the value of the x variable into the top equation and solve for the y variable:

5(0) - 4y = -24

-4y = -24

y = 6

Therefore, x = 0 and y = 6.

Hope this helps!! :)

The number of volunteers to walk dogs at the local animal shelter last year was 20 this year the number of volunteers has risen

Alex73 [517]

There is 150% increase in the number of volunteers.

Step-by-step explanation:

Given,

Old number of volunteers = 20

New number of volunteers = 50

Change = New value - Old value

Change = 50 - 20 = +30

The positive sign indicates the increase.

Percent increase = $\frac{Change}{Old\ value}*100\\$

$Percent\ increase=\frac{30}{20}*100\\\\Percent\ increase=\frac{3000}{20}\\\\Percent\ increase=150\%$

There is 150% increase in the number of volunteers.

Which expression is equal to 4/8

givi [52]

<h2>Fractions</h2>

Which expression is equal to $\large\tt \frac{4}{8}$ ?

Option 1

$\large \tt 4 \times \frac{1}{2} = \frac{4}{1} \times \frac{1}{2} = \red{\frac{4}{2}}$

Option 1 is not equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$

Option 2

$\large \tt 3 \times \frac{1}{5} = \frac{3}{1} \times \frac{1}{5} = \red{\frac{3}{5}}$

Option 2 is not equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$

Option 3

$\large \tt 3 \times \frac{1}{8} = \frac{3}{1} \times \frac{1}{8} = \red{\frac{3}{8}}$

Option 3 is not equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$

Option 4

$\large \tt 4 \times \frac{1}{8} = \frac{4}{1} \times \frac{1}{8} = \green{\frac{4}{8}}$

Therefore, option 4 is equal to $\large\tt \frac{4}{8}$

Your neighbor also has a swimming pool of the same shape as yours, but it is 75% the depth. Your pool is 1015 cubic feet. What i

Nastasia [14]

Answer:

761 cubic feet.

Step-by-step explanation:

Your neighbor also has a swimming pool of the same shape as yours, but it is 75% the depth.

Then, if my swimming pool's depth is H, then my neighbor's pool will have depth $\frac{75 \times H}{100} = 0.75 H$ .

So, if my swimming pool has dimensions L ft. by W ft. by H ft., then my neighbor's pool will have dimensions L ft by W ft. by 0.75H ft.

Now, given that the volume of my pool is 1015 cubic ft.

So, LWH = 1015 ......... (1)

Now, my neighbor's pool has volume V = 0.75LWH = 0.75(1015) = 761.25 cubic ft ≈ 761 cubic ft. {Round to the nearest whole number} (Answer)

{From equation (1)}
