12/7. You put the numbers into mixed numbers giving you 18/7 and 9/6. For division you flip the second fraction and multiply them together. So you do 18/7 x 6/9. You're also able to cross cancel 18 and 9 giving you 2/7 x 6/1. 6 x 2 is 12 and 7 x 1 is 7. Your answer is 12/7.
When solving two step equations you must solve one part of the equation so that you can solve the second part.
In one step equations you can just solve the equation as is.
The correct answer to place y minus 12 in an algebraic expression is simply
y - 12
Answer:
0.52 km
Step-by-step explanation:
We are given that
Speed of object, v=
Speed of object, v=
Distance travel by object, s=
Distance travel by object, s=
We have to find the time taken by object to travel 5 1/10 km.
We know that

Using the formula
Time taken by object to travel 5.1 km =
Time taken by object to travel 5.1 km=0.52 hr
