Trey read 10 pages in 25 minutes at at this rate how many pages will he read and 45 minutes
Answers
Trey will read 18 pages in 45 minutes.
This is because he read 2.5 pages a minute. 25/10 = 2.5 so if we 45/2.5 = 18
10 pages per 25 min. and now there is 45. Divide 45 by 25 and get 1.8, so not multiply 10 by 1.8 : 10 • 1.8 = 18. Trey reads 18 pages in 45 minutes. Hoped I helped!
There are two identical figures with all sides of equal length. The combined perimeter of the figures is 80 centimeters. What shape are the figures? What is the length of one side?
Answers
Since both shapes are the same,we divide the total perimeter by 2. 80÷2 is 40. Now that we have the perimeter of each individual shape we have to figure out the length of one side. Since all the sides are equal in length there is only 1 shape that has that - a square. A square has 4 sides so we need to divide 40 by 4 (because squares have 4 sides) and that equals to (40÷4) 10cm on each side. Hope I helped!
Evaluate -3+y/5 when y = –2.5
Answers
If you would like to evaluate - 3 + y / 5 when y = - 2.5, you can calculatethis using the following steps:
When we have the value for the variable, all we have to do is apply the number to replace the variable, then solve.
-3+y/5 will turn into :- -3+-2.5 -5.5 ------------------ = -------------= -1.1 5 5
Now we need to divide -5.5 by 5. We get -1.1
Our final answer: -1.1
A veterinarian has found that 4 cat years equal 32 human years, and 8 cat years equal 48 human years. Are cat years proportional to human years? Explain your reasoning.

I need help on this one question please someone help me pleases
Answers
so we simplify this and do 5(3a-1)-2(3a+2)=3(a+2)+v 15a-5-6a-4=3a+6+v add like terms 9a-9=3a+6+v subtract 6 from both sides and get 9a-15=3a+v subtract 3a from both sides and get 6a-15=v or 3(2a-5) so the answers are D,E
or if you want to avoid doing allot of math, you could just figure out which two answer choices are the same (D,E)
5(3a-1)-2(3a+2)=3(a+2)+v 15a-5-6a-4=3a+6+v 9a-9=3a+6+v 9a-15=3a+v 6a-15=v or 3(2a-5) so the answers are D,E SORRY I GOT THE OTHER WRONG!
