Answer:

50 and 28

Step-by-step explanation:

x+y=78

x-y=22

to find this, subtract 22 from 78 to get 56

divide 56 by 2 to get 28

y=28

add 22 to 28 to get 50

x=50

to double check add 50 and 28 to get 78

also subtract 28 from 50 to get 22

Answer:

The average per week flow rate of students to the gym is <u>2700</u>.

Step-by-step explanation:

Given:

Baruch college has 1000 students in the spring of 2018. 30 percent of the students use the gym twice per week, 70 percent of the students use the gym three times a week.

Now, to find the average per week flow rate of students to the gym.

Total number of students = 1000.

So, 30 percent of the students use the gym twice per week:

$30\%\ of\ 1000\times 2\\\\=\frac{30}{100}\times 1000\times 2\\\\=0.30\times 1000\times 2\\\\=600.$

Now, 70 percent of the students use the gym three times a week:

$70\%\ of\ 1000\times 3\\\\=\frac{70}{100} \times 1000\times 3\\\\=0.70\times 1000\times 3\\\\=2100.$

Now, to get the average per week flow rate of students to the gym by adding 30 percent of the students use the gym twice per week and 70 percent of the students use the gym three times a week:

$600+2100$

$=2700.$

Therefore, the average per week flow rate of students to the gym is 2700.

Ivahew [28]

Ok so $2.05 + $15 = $17.05 so you want to try to spend the same amount of money in each store so what have to do is figure out the number of gallons you buy in each store i added 2 gallons for the first store so the amount would be $2.05(2) + $15= $21.15 so now to find the x in the next equation you have divide the sum by $2.35 which give you 9 gallons now you spent the same amount in each store so you paid for 11 gallons hope you give me brainliest answer lol
