Answer:

4:10, 2:5

Step-by-step explanation:

We want to know what ratios are equivalent or equal to one another.

5:4 could be done with 10:8 not 10:6 so #1 is out

1:3 could be done with 1:3 not 1:4 so #3 is out

3:11 could be done with 6:22 and 9:33 not 9:22 so #4 is out

4:10 could be done with 2:5 and 8:20 so this is it.

In order to know what it could be done with you want to multiple the numbers by two. Or Divide by two.

Solve 2-18x-6=-7x+3+10x
Temka [501]

Answer:

x= -1/3

Step-by-step explanation:

First, we can combine like terms on each side:

-4-18x=3x+3

Then, we move all of the variables onto one side and the constant onto the other:

-18x-3x=3+4

-21x=7

x=-7/21

x= -1/3

Hope this helps!
