Evaluating the given expression for when x = 3. y = 2x + 3

9

Step-by-step explanation:

We need to substitute value of x and calculate.

y=2x+3

y=2*3+3=6+3=9

y=9

X=3

Y=2x + 3

Substitute x in the equation as 3. Therefore you will have

Y=2(3)+3

Y=6+3

Y=9

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
