Answer:

x = y/9 - 7/9

Step-by-step explanation:

Solve for x:

4 y - 36 x = 28

Subtract 4 y from both sides:

-36 x = 28 - 4 y

Divide both sides by -36:

Answer: x = y/9 - 7/9

If enrollment increases by approximately the same

Tanya [424]

Given:

The enrollment increases by approximately the same percentage between 2000 and 2010 as it decreased between 1950 and 1960.

To find:

The expected enrollment in 2010.

Solution:

Percentage decrease formula:

$\%\text{ decrease}=\dfrac{\text{Initial value - New value}}{\text{Initial value}}\times 100$

The percentage decrease in between 1950 and 1960 is:

$\%\text{ decrease}=\dfrac{4-3.5}{4}\times 100$

$\%\text{ decrease}=\dfrac{0.5}{4}\times 100$

$\%\text{ decrease}=\dfrac{50}{4}$

$\%\text{ decrease}=12.5$

The enrollment decreased by 12.5% between 1950 and 1960. So, the enrollment increases by 12.5% between 2000 and 2010.

The expected enrollment in 2010 is:

$\text{Expected enrollment}=7+\dfrac{12.5}{100}\times 7$

$\text{Expected enrollment}=7+0.875$

$\text{Expected enrollment}=7.875$

Therefore, the expected enrollment in 2010 is 7.875 thousands.

Jake heard that as a general rule, he should spend no more than one week's pay on rent. If Jake's salary is $24,700 per year, wh

musickatia [10]

The <u>correct answer</u> is:

$475

Explanation:

Jake earns $24,700 per year. If he spends no more than one week's pay on rent per month, we need to know how much of this salary he earns each week. There are 52 weeks in a year, so we divide 24700 by 52:

24700÷52 = 475.

Jake earns $475 each week, so he should spend no more than this in rent.

Girls backyard is in the shape of a rectangle that has a length of 19.5 ft it cost 945 to fence in the yard if the cost is $15 p

alisha [4.7K]

You need to know the formula for the perimeter of a rectangle. We won't use it right away, but it is pertinent information.P = 2 ( l + w )Now, we know that the fencing costs $15.00 per foot, and that the length is 19.50 feet. We first need to find the price of one "length" side of the fence. To do this, multiply 19.50 by 15.0019.50 x 15.00 = 292.5Next, we look at the perimeter equation to see what we can plug in where.P = 2 ( l + w )We can put in the total price of the fencing for the yard as P, and the amount of one length side of the fence as l.945.00 = 2 ( 292.5 + w )And now, we simply solve for w.945.00 ÷ 2 = ( 2 ( 292.5 + w ) ) ÷ 2472.5 = 292.5 + w472.5 - 292.5 = 292.5 + w - 292.5w = 180It costs $180 for one "width" side of the fence. To find out how many feet that is, we do the opposite of what we did with the length. Instead of multiplying by $15.00, we divide by $15.00$180.00 ÷ $15.00 = 12The width of Claire's backyard is 12 feet

In the figure below, g || 1. Find the values of y and x.<br>

Advocard [28]

Answer:

x = 26 degrees.

y = 106 degrees.

Step-by-step explanation:

3x - 4 = 74 (exterior alternate angles).

3x = 78

x = 26.

y = 180 - 74 = 106.
