A taxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or F = $2.25 + $0.20(m - 1) wh

gavmur [86]

Answer: Juan travelled 28 miles in the taxi

Step-by-step explanation:

A taxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile. This means that for m additional miles, the charge will be 2.25 + 0.20(m - 1)

So if F represents the fare, then

F = $2.25 + $0.20(m - 1)

If Juan's taxi fare was $7.65, to determine the number of miles that she paid for, we would substitute F = $7.65 into the equation,

F = $2.25 + $0.20(m - 1). It becomes

7.65 = 2.25 + 0.20(m-1)

7.65 = 2.25 + 0.20m - 0.20

7.65 - 2.25 + 0.20 = 0.2m

0.2m = 5.6

m = 5.6/0.2 = 28 miles

The length of the rectangle is three times its width.The perimeter of the rectangle is at most 112 cm .

Slav-nsk [51]

Option D is the correct answer

$2w+2.(3w)\leq 112$

Further explanation:

Let

$l\ be\ the\ length\ of\ rectangle\\and\\w\ be\ the\ width\ of\ rectangle$

The perimeter of a rectangle is given by:

$P=2w+2l$

It is also given that:

$P\leq 112$

So we can write as

$2l+2w\leq 112$

We also know that The length of the rectangle is three times its width

$l=3w$

Putting the value of l in the inequality

$2.(3w)+2w\leq 112$

Rearranging the terms

$2w+2.(3w)\leq 112$

Hence, option D is the correct answer.
