Answer: 440

Step-by-step explanation:

5 * 5 = 25

8 * 5 = 40

40 * 4 = 160

160 + 25 = 185

10 * 10 = 100

100 - 25 = 75

10 * 2 = 20

20 * 4 = 80

75 + 100 + 80 + 185 = 440

Use the equation k = x÷ y to find the constant of proportionality for the set of values
Lubov Fominskaja [6]

The constant of proportionality is 1/3

and three more values are

x       1        2        3        4        5        

y       3       6        9        12       15

<h3>Variation</h3>

From the question, we are to determine the constant of proportionality

The given equation is

k = x ÷ y

From the given information,

When x = 1, y = 3

∴ k = 1 ÷ 3

k = 1/3

Thus, the constant of proportionality is 1/3

Now, we will determine the values of y for the values x = 3, x = 4, and x = 5

Since

k = x ÷ y

Then,

y = x ÷ k

When x = 3

y = 3 ÷ 1/3

y = 3 × 3

y = 9

When x = 4

y = 4 ÷ 1/3

y = 4 × 3

y = 12

When x = 5

y = 5 ÷ 1/3

y = 5 × 3

y = 15

Hence, the constant of proportionality is 1/3

and three more values are

x       1        2        3        4        5        

y       3       6        9        12        15
