! stuck on 2

the time is takes to mow the lawn at a large park m(x) varies inversely with the numbers of workers assigned to the job x. it takes 90 minutes to complete the job when 3 workers are assigned to it.

which equation can be used to find the time to complete the job when x workers are assigned to it?

a.) m(x)= 270/x
b.) m(x) = 270x
c.) m(x) = 30/x
d.) m(x) = 30x

2. suppose that h(x) varies inversely with x and h(x)=50 when x =0.25

what is h(x) when x =2?

a.) 0.5
b.) 6.25
c.) 12.5
d.) 24

can you also provide how you got the answer as well : )

For the first question, the answer is A. You take 90 and multiply it by 3, then you get the time that it takes for one worker to mow the large park. 

For the second question, you take 50 = k/0.25. To find k, you would want to multiply both sides with 0.25 to cancel the 0.25 on k's side. 50 times 0.25 is 12.5. I think C is your answer although I'm not really confident.

x=4 so both the answer is 0

Step-by-step explanation:

3x-12=x-4

3x-x=-4+12

2x=8

2x÷2=8÷2

x=4

so

3x-12=4-x

3×4-12=4-4

12-12=4-4

0=0
