Ken has to rent a car for a week and to pay no more than $130. How far can he drive if the car rental costs $94 a week plus $0.4

Elena-2011 [213]

Answer:

So he can travel a total of 90 miles

Step-by-step explanation:

Given:

Total he has to pay = $130

Per week cost = $94

Per mile cost = $0.40

To Find:

No of miles = ?

Solution:

The total he has to pay can be found out by the equation

Total = weekly cost + Miles cost

Now here

Miles cost = total no of miles traveled * per mile cost

This is due to the reason that he is travelling miles and we have to multiply it with it per mile cost to get the total miles cost

so

Let Total miles traveled be x then

Miles cost = $ 0.40 * x

Now we have

Total = weekly cost + Miles cost

Putting in the values we get

130 = 94 + 0.40 *x

subtracting 94 from both sides

130-94 = 94 + 0.40*x - 94

36 = 0.40*x

Dividing both sides by 0.4 we get

$\frac{36}{0.4}=\frac{0.4*x}{0.4}$

90 miles = x

or x= 90 miles

So he can travel a total of 90 miles

What is the equation of a line that passes through the points (-3,4) and (2, 8

slavikrds [6]

Answer:

y = 4/5x + 32/5

Step-by-step explanation:

(-3,4) and (2, 8)

Slope:

m=(y2-y1)/(x2-x1)

m=(8-4)/(2+3)

m= 4/5

Slope-intercept:

y - y1 = m(x - x1)

y - 4 = 4/5(x + 3)

y - 4 = 4/5x + 12/5

y = 4/5x + 32/5

The Rodriguez family and the Hill family each used their sprinklers last summer. The water output rate for the Rodriguez family'

brilliants [131]

Answer:

x = 23.33 hr Rodriguez sprinkler

y = 26.66 hr Hill sprinkler

Step-by-step explanation: INCOMPLETE QUESTION

Requiered information:

the water output rate for both sprinkler families

We assume : Rodriguez family 40 lts/hr

Hill family 35 lts/ hr

Total water output 1900 lts

and total combined hours working is 50 hr

Let call "x" time in hours sprinkler of Rodriguez family worked

and "y" time in hours sprinkler of Hill family worked

Then if total output was 1900 lts

40*x + 35*y = 1900 and x + y = 50

We have a two equation system, solving

y = 50 - x ⇒ 40*x + 35 * ( 50 - x )

40x = 1750 - 35x

75 x = 1750 ⇒ x = 1750/75 ⇒ x = 23.33 hr

and y = 50 - 23.33 ⇒ y = 26.66 hr
