First you'll need to get the same denominator. So instead of 3/5 and 3/8 you'll have 24/40 and 15/40. Now that we've changed the value of the denominator, the 40/40 will now represents the 1 hour that Jenny has before bedtime. So you add 24/40 and 15/40 and get 39/40. 39/40 stands for the time that Jenny has already spent brushing her teeth and texting her friend all together. Since the 1 hour is 40/40 subtract 39/40 from it to get 1/40. 1/40 is equal to the rest of the time Jenny spends reading or 1.5 minutes.
Answer: What is the question
Step-by-step explanation:
4x+13=5x-12
-4x. +12
25=x
3(25)-8=4y+7
75-8=4y+7
67=4y +7
-7
60=4y
y=15
lol i know this is correct bc this was a problem on my homework a couple days ago and i got it right
Lets say... 7 divided by 21. ok? So... Just take 7, (usually the smaller number, but not in all cases.) and then multiply it by 1. 2. 3. So lets see. 7x1=7 so thats not it. 7x2 is 14 so thats not it. And you want to keep doing that until you get the other number. 7x3 is 21!!! That is the correct number so if you were doing long division like this
___3______ <--- the answer would be there.
7|21
The unit for mass is grams, or g.
