Answer:

100 minutes

Step-by-step explanation:

Let x = # of minutes

Company A: y = 21 + .17x

Company B: y = 26 + .12x

Set the equations = to each other.

21 + .17x = 26 + .12x

.17x = 5 + .12x

.05x = 5

x = 100

It was recently estimated that females outnumber males by about three or two. If there are 1770 people in a county, how many of

max2010maxim [7]

GIVEN

1) Females outnumber males by 3 to 2.

2) There are 1770 people in the city.

SOLUTION

Let the number of males be x and the number of females y. Therefore, the total number of people can be written to be:

$x+y=1770\text{ -----------(1)}$

If there are 3 females for every 2 males, we have that:

$\begin{gathered} \frac{y}{3}=\frac{x}{2} \\ \therefore \\ x=\frac{2y}{3}\text{ ----------(2)} \end{gathered}$

We can substitute equation (2) into equation (1) and solve for y:

$\begin{gathered} \frac{2}{3}y+y=1770 \\ \frac{2y+3y}{3}=1770 \\ 5y=1770\times3 \\ 5y=5310 \end{gathered}$

Dividing both sides by 5, we have

$y=1062$

There are 1062 females in the county.

levacccp [35]

Let's review all the answers that it could be.
A. The hundredths place is 10 times smaller than the tenths place, so the answer cannot be A.

B. This one makes sense, 10 is 10 times greater than 1 so the answer should be B, but let's just check the others to be sure.

C. This is the same as answer A. Hundredths is actually smaller than tenths, so the answer cannot be C.

D. This one does not give adequate information.

I believe the answer is B.The 4 in the tens place is 10 times the value of the 4 in the ones place.
