2x + 5(y - 1) when x=8 and y=5

Your answer would be 36

Step-by-step explanation:

First you start off by rewriting the equation to make it simpler for you to understand all of the steps.

Then you plug in your given values. (x = 8 and y = 5)  

After you plug in your given values you solve all your parenthesis (aka using the Distributive Property of Equations to simplify your equation.)

After that, you have basic math

And now your answer is 36.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
