I need help on khan academy again!!

7/2 times the 2 by 5 to get 10

3/5 times 5 by 2 to get 10

Step-by-step explanation:

1: 35/10

2:6/10

Step-by-step explanation:

multiply the dom to equal 10 and whatever you multiply the dom with do with the num. example 5*2=10 so 3*2=6

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

i think the answer is b.

step-by-step explanation:

not 100% sure though.
