R + d = 1750
r = d + 450
d + 450 + d = 1750
2d + 450 = 1750
2d = 1750 - 450
2d = 1300
d = 1300/2
d = 650 <=== what Dustin pays
r = d + 450
r = 650 + 450
r = 1100 ...Robert pays 1100
Answer:
(D) 
Step-by-step explanation:
Two variables x and y are proportionally related if they can be written in the form y=kx, where k is the constant of proportionality.
From the given options, if 
(B)
is of the form y=kx
(C)
is of the form y=kx with as 
in its lowest form.
(C)
is of the form y=kx with as 
in fractional form.
On the Contrary,
In Option D, does not represent a proportional relationship between x and y. The constant of proportion is supposed to be a product of x.
Answer:
Step-by-step explanation:
you set the equation and try to bring it over one
i will do one of them for you
$9.40 for 5 cans of soup
to find what one can costs, divide 9.40 by 5
and you get $1.88
or you can set a proportion
9.40 x
--------- = ----------
5 1
cross multiple
5x=9.40
x=1.88
This means it’s 6(3)^2. The PEMDAS process will help in this situation. Since exponents (E) come before multiplication (M), you would raise 3 to the 2nd power first. 3^2 is the same as 3 times 3, which equals 9. Now, you can multiple 6 by 9, which would result with 54. 54 is your answer!
1 - 5
2 - 7
3 - 9
4-11
5-13
6-15
7- 17
8 - 19
9 - 21
10 - 23
