X is partly constant, and partly varies as y. When y= 2 , x = 30 and when y = 6, x = 50

kirza4 [7]

"X is partly constant and partly varies as y"

---> x = ky + p

when y=2,x=30 ---> 30 = 2k + p

when y=6,x=50 ---> 50 = 6k + p

subtract: 20 = 4k

k = 5

sub back in the first: 30 = 10+p

p = 20

x = 5y + 20

now you can answer B

notice this is just a variation of y = mx + b

identify the equation that does not belong with the other three. explain your reasoning. 6+x=9 | 15= x+12 | x+9 =11 | 7+x=10

Katena32 [7]

Answer is x+9=11

6+x=9
x=3

15=x+12
x=3

7+x=10
x=3

x+9=11
x=2

So x+9=11 has a different x value than the rest of the equations. So it doesn't belong with the other three.

By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.

<h3>What is percentage ?</h3>

Percentage is a number or ratio expressed as a fraction of 100.

Here given that

Marilyn has two credit cards, D and E. Card D has a balance of $691. 64, and Card E has a balance of $1,014. 22. The minimum monthly payment on Card D is 3. 57% of the total balance, and the minimum monthly payment on Card E is 2. 51% of the total balance

So minimum balance of Card D is 3.57 Percentage of $ 691.64

$=3.54\times\frac{691.64}{100} =24.691548=24.69$

minimum balance of Card E is 2. 51 Percentage of $1,014. 22.

$=2.51\times\frac{1014.22}{100} =25.456922=25.46$

Now we can see that minimum balance of Card E is 25.49-24.69=0.77 extra that on D

By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.
