Which equation has a constant of proportionality equal to 7?
A. 4y = 28x
B. 7y = 28x
C. 28y = 4x
D. 28y = 7x

Answers

Answer 1
A is correct.

Reasoning: 4 x 7 = 28


good luck!
Answer 2

The solution is Option A.

The equation which has a constant of proportionality k = 7 is 4y = 28x

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the equation be represented as A

Now , the value of A is

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

Now , the equation is

4y = 28x

On simplifying the equation , we get

Divide by 4 on both sides of the equation , we get

y = 28x/4

y = 7x

y = 7x is of the form y = kx where the value of k is 7

Therefore,  the value of k is 7

Hence , the value of proportionality constant is 7

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

given that,

Julie uses 4 green beads and 6 blue beads in each bracelet she makes.

Julie will use when she uses 24 blue beads

we have to find the total number of green beads Julie will use when she uses 24 blue beads

so, we have,

4 green beads and 6 blue beads in each bracelet

i.e. green beads : blue beads = 4 : 6

now. let, x green beads Julie will use when she uses 24 blue beads

i.e. green beads : blue beads = x: 24

we get,

4 : 6  = x: 24

so. x = 4 * 24 / 6

24 divided by 6= 4

4x4=16

we get,

For every 6 blue beads Julie used she used 4 green and she made 4 brackets so times 4x4 getting you to 16

Hence. 16 green beads Julie will use when she uses 24 blue beads.
