Wilma can mow a lawn in 90 minutes. Vanessa can mow the same lawn in 30 minutes. How long does it take for both Wilma and Vanessa to mow the lawn if they are
working together?

If it takes Wilma 90 minutes and Vaness 30 minutes you'll need to add 90 + 3.

If add both numbers correctly the answer that you'll get will be 2 hours.

Hope this helped :)

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
