Answer:

120 miles

Step-by-step explanation:

we know that

The speed is equal to the distance divided by the time

Let

s------> the speed in mph

d-----> the distance in miles

t -----> the time in hours

s=d/t

solve for the distance

d=s*t

<em>It will take Adam four hours to drive to Disney Park</em>

s=x mph

t=4 h

substitute

d=4x -----> equation A

<em>It will take Adam 2.5 times less time if driving 45 mph faster</em>

so

s=(x+45) mph

t=4/2.5=1.6 h

substitute

d=1.6(x+45) -----> equation B

equate equation A and equation B

4x=1.6(x+45)

Solve for x

4x=1.6x+72

4x-1.6x=72

2.4x=72

x=30 mph

Find the distance d

d=4x -----> d=4(30)=120 miles

52,908 round to the nearest hundred.
IrinaVladis [17]

The hundredth is the 3rd number after the decimal place (so the 9). Look at the number before it and if it is 5 or above then round it to the next hundredth. In this case it is only a zero so we don't change the 9 just substitute it 0's. Therefore the answer is 52,900.

If you need further help let me know, hope this helped you.

Lilit [14]

Your answer is 110/119

11/17 Divided By 7/10

11 * 10

17 * 7

110/119

That number can't be simplified, so that is your final answer.

Best of luck,

A pencil costs .27 and a pen costs .32. You buy six pencils and the total cost is 4.18 How many pens did you buy?
skelet666 [1.2K]

Answer:

8 pens

Step-by-step explanation:

<h2><u>Finding the number of pens bought </u></h2>

pencil costs 0.27

pen costs 0.32

6 * pencils + x pens = 4.18

6 * 0.27 + x * 0.32 = 4.18

1.62 + 0.32x = 4.18

0.32x = 4.18 - 1.62

0.32x = 2.56

x = 2.56/0.32

x = 8

<u>hence 8 pens were bought </u>
