Ok,so you can represent the students as K and Y as the cookies eaten.X is your  constant of proportionality (the number you multiply to k to get y).

For the first one,14/2 which equals 7.Try the next set,21/3=7 also and finally 35/5=7.You can see that the C.O.P is 7.

−2 1/4=r−4/5<br><br> What is r?
dmitriy555 [2]

Answer:

r = -29/20 or r = -1.45

Step-by-step explanation:

I believe you are saying that the equation is -2 1/4 = r - 4/5. If so, then I would solve it in this way:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-9/4 (20) = r (20) - 4/5 (20)

-45 = 20r - 16

20r = -29

r = -29/20

r = -1.45

Check:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-2.25 = r - 0.8

-2.25 = -1.45 - 0.8

-2.25 = -2.25

-9/4 = -9/4

Determine the constant of varlation for the direct variation glven. Rvaries directly with S. When S is 16, R Is 80.​
navik [9.2K]

Answer:

The constant of variation is 5.

Step-by-step explanation:

In direct variation, as y varies directly with x, the standard equation is

y = kx,

where k is the constant of variation.

In your case, we use R and S. R varies directly with S, so we have

R = kS

We know that when S = 16, R is 80, so we plug in those values and solve for k, the constant of variation.

R = kS

80 = k(16)

k = 80/16

k = 5

You have an allowance to spend on lunch this week. You will spend the same amount each day,and you get to keep whatever is left
Naily [24]

Answer:

The total allowance is $18.5, and the amount spent daily is $3.2

Step-by-step explanation:

let T and x represent the total allowance and the amount spent daily respectively.

It was started that the amount remaining after 2 days is $12.10 , which implies the person has spend an equal amount for 2 days

T - 2x =12.10       (equation 1)

It was started that the amount remaining after 5 days is $2.50  , which also implies the person has spend an equal amount for 5 days

T - 5x =2.5       (equation 2)

subtract equation 2 from 1

T - 2x -( T - 5x ) = 12.10 -2.5

T - 2x -T + 5x = 9.6

3x =9.6

Divide both side by 3

x = 9.6/3 =3.2

from equation 1

T - 2x =12.10  

T = 12.10 + 2x = 12.10 + 2*3.2

= 12.10 + 6.4 = 18.5
