HURRY PLEASE IM BEING TIMED 46 points! Which error did Carolyn make while solving the system of equations

She did not distribute the negative to the 2 in the parenthesis

Step-by-step explanation:

should have been:

3x - 2(x+2) = 7

3x-2x-4=7

x=11

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

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
