Answer:
the correct answer is -5 since y=7
(1/6) / (1/4) = x / 1....1/6 acre to 1/4 hr = x acres to 1 hr
cross multiply because this is a proportion
(1/4)(x) = (1/6)(1)
1/4x = 1/6
x = 1/6 * 4/1
x = 4/6 which reduces to 2/3....so she can mow 2/3 of an acre in 1 hr <=
Answer:
The correct answer is D because they are unknown
Step-by-step explanation:
We are going to denote the number of additional minutes with

, and the total cost of the call with

.
From PONCO, we know that they charge $1.25 for the first minute, and $0.30 for each additional minute; knowing that our additional minute is

and our total cost of the call is

, we can set up an equation to relate the values:

we are going to call this equation (1)
From CowBell, we know that they charge 1.40 for the first minute, and $0.25 for each additional minute. so just like before we can set up an equation to relate the values:

We are going to call this equation (2)
Since the total cost

of equations (1) and (2) is the same, we can equate them to find

:




We can conclude that after 3 additional minutes the cost of the calls will be the same; therefore, the correct answer is
B.
