The Quinn family drove 228 miles in 4 hours at a constant rate. Which equation can be used to determine how far they traveled each hour?
Answers
What can be used on this is the distance over time formula, so what you,do is divide 228 by 4 to get the distance traveled in one hour. And 288/4=57. So they traveled 57 mi in one hour. Hope this helped.
Okay, so all you would have to do is find the unit rate, and to do that, you would divide 4 INTO 228, (228 divided by 4), which would be 57, so they drive 57 miles PER HOUR. I hope I helped! =D
18x + 9y use the distributive property to write an equivalent expression
Answers
Hey there! It looks like you have another factoring question! Using our definition of the distributive property: a(b+c) = ab+ac We need to factor our or greatest common multiple, which here is 9. 9 times 2x = 18x and 9 times y = 9y We have: 9(2x + y) Once again, using the distributive property, multiply it out and you'll get 18x and 9y. Hope this helps!

First take away fifty from both sides 25w = 350 Divide 25 from both sides Answer is: w = 14
So, it will take Uma 14 weeks to save enough money to but the video game system.
