The function y = 3.75 + 2.50(x - 3) can be used to determine the cost in dollars for a uber ride of x miles. What is the rate of

stepan [7]

The cost of each mile is $2.50.

If you simplify the expression given you will get the following.
y = 3.75 + 2.50(x - 3)
y = 3.75 + 2.50x - 7.50
y = 2.50x - 3.75.

Knowing that x is the number of miles and 2.50 is the number being multiplied by, we know that the cost per mile is 2.50.

The length of a rectangle is 5 more than twice the width. the perimeter is 130 inches. what is te area

Brut [27]

The length of a rectangle:
L = 2 W + 5
The perimeter:
P = 2 L + 2 W
130 = 2 · ( 2 W + 5 ) + 2 W
130 = 4 W + 10 + 2 W
130 - 10 = 6 W
120 = 6 W
W = 120 : 6
W = 20 in
L = 2 · 20 + 5
L = 40 + 5
L = 45 in.
Finally the area:
A = L · W
A = 20 · 45
A = 900 in²

A boat traveled 37 miles in 2 hours. At this rate, how many miles will the boat travel in

Inessa [10]

Answer:

i. The boat will travel 18.5 miles in one hour

ii. The boat will travel 9.25 miles in half an hour

iii. The boat will travel 27.75 miles in one and a half hours

Explanation:

We are given that the boat travel 37 miles in 2 hours

To get the miles traveled, we can simply use cross multiplication

i. Miles traveled by the boat in one hour:

37 miles .....................> 2 hours

x miles ........................> 1 hour

$x = \frac{37*1}{2}=18.5$ miles

ii. Miles traveled in half an hour:

37 miles .....................> 2 hours

x miles ........................> 0.5 hour

$x = \frac{37*0.5}{2}=9.25$ miles

iii. Miles traveled in an hour and a half:

37 miles .....................> 2 hours

x miles ........................> 1.5 hour

$x = \frac{37*1.5}{2}=27.75$ miles

Hope this helps :)
