Help me solve for q!<br><br> 21 + 3q &lt; 3 (13 - q)<br><br> How do you solve it? Thank you!
Molodets [167]
Good morning

21 + 3q < 3(13 - q)
21+ 3q < 39 - 3q Here it was -3q and it was on the left side. However when you are switching it to another terms that looks like it you must change the sign as well.
3q + 3q < 39 - 21 Here I bring the common terms together.
6q < 18
Divide both sides by 6
6q/6 < 18/6
q < 3

A bottle contains 3.5 L of water. A second bottle contains 3750 mL of water. How many more millimeters are in the larger bottle
weeeeeb [17]
Hey there,
3.5 L = 3.5 x 1000
         = 3,500 mL
The second bottle has more water than the first bottle,
3,750 mL - 3,500 mL = 250 mL

Hope this helps :))

What is 39/3 as a mixed number?
likoan [24]
Converting to a mixed number is the same as dividing and leaving the remainder.
Say we had 5/2...we would divide 5 by 2 and end up with 2 r1, right?
So 5/2 = 2 1/2

As for 39/3...we divide 39 by 3...and get exactly 13! There's no remainder, so you don't even need any additional fractions.
