Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result

x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7

x=4, y=28, 28=k(4), k=7

The constant of proportionality is 7; we check 2×7=14, 11×7=77

Answer: k=7, y=7x

Answer:

y=kx

y=k(7)x

y=7x(11)

y=7*11

y=77

Step-by-step explanation:

So with useing the equation that I used the porportional relationship is 7 so just fill 7 in for k. Then take the x number and fill it in for x. you will then multiply and get the y value.

Answer:

The price of each meal cost before tax is $ 6.367

Step-by-step explanation:

Given as :

The total price of three meals = $ 20.25

The sales tax included in the total price = 6 %

So, Let the cost of meal before sales tax = x

Or, x + 6 % of x = $ 20.25

or, x + 0.06 x = $ 20.25

Or, 1.06 x = $ 20.25

∴ x = $\frac{20.25}{1.06}$

I.e x = $ 19.10

Or, price of three meals before tax = $ 19.10

so, The price of each meal = $\frac{19.10}{3}$ = $ 6.367

Hence The price of each meal cost before tax is $ 6.367 answer
