6. Simplify (3 1/2+7) divided by (4 4/3-3). a
7. A car travels 72km in an hour. find its speed in m/s.

Ok

Step-by-step explanation:

no. 6 the answer is 0

no. 7 speed = dist /time

=>72/1

=> 72km/hr conversation to m/s

=> 72 × 1000/3600

=> 20m/s

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

its kind of blurry. can you put a clearer pic?
