Answer:
These are both 20 so that means that this is proportional, yes.
Step-by-step explanation:
Hi.
To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.
Here is how we do this.
So basically what we are doing is multiplying across in a diagonal direction.
Diagonal meaning like a slash / .
So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.
Do the same for the 2 and the 10.
So we have to multiply :
4 x 5
2 x 10
=
20
These are both 20 so that means that this is proportional, yes.
Hope this helps.

Answer:
55 marbles
Step-by-step explanation:
1) x+17+x=126
2)2x=109
3)x=54.5
4)Round up to 55
Yes you are doing it right because 7*5=35 and 8*3=24.
Answer:
52 people
Step-by-step explanation:
If you place 25 square tables in a line, the 23 tables in the middle can only seat 2 people each since the other two sides are touching two other tables. The end two tables can seat 3 people since only one of their sides is touching another table.
So multiply 23 by 2 to find out how many people are sitting in the middle and then add 6 people for the two tables on the end.
23(2) + 3(2) = 52 people
To solve problem 1 what you need to do is figure out how many miles the girls have walked so far and then subtract that from the total distance they must complete.
3/4-(3/10+1/4)
Step 1:Change the denominators so that way they are all the same
3/4=15/20
3/10=6/20 15/20-(6/20+5/20)
1/4=5/20
Step 2: Begin solving the problem
6/20+5/20=11/20
15/20-11/20=4/20
Step 3: Simplify your answer
4/20=1/5
Step 4 (is optional): Write your answer in a complete statement
