Answer:
x = 25
Step-by-step explanation:
3x = 75
divide both sides by 3
x = 25
9x - 24 + 4x = -24 + 14x - x
13x - 24 = 13x - 24
0 = 0
Answer is All real numbers
Answer:
15 minutes
Step-by-step explanation:
Betty mows at 3 times the speed that Bullwinkle does, so is equivalent to having 3 Bullwinkles in her place. That makes the lawn get mowed as though 4 Bullwinkles were working, so it will take 1/4 the time it takes Bullwinkle to mow the whole yard. 1/4 of 60 minutes is 15 minutes.
Working together, Betty and Bullwinkle will take 15 minutes to mow the lawn.

Explanation
As you can see all the possible answers have the same form:

By looking at the picture you'll notice that the graph of g(x) has to pass through the point (2,1). Remember that the points in the graph of g(x) have the form (x,g(x)). Since (2,1) is part of the graph of g(x) then we have the following:

So let's evaluate the expression for g(x) that we wrote before at x=2. This way we'll obtain an equation for the number a:

Then we can divide both sides by 4:

Then we get:

Answer
Then the answer is option A.
