7/12 of 1 hour:

1 hour = 60 min.

7/12 * 60

7 * 5 = 35

Francis ran 2 1/2 miles in 35 min.

2 1/2 = 5/2


5/2 miles = 35 min

x miles = 60 min

(Cross Multiply)


5/2 * 60 = 35x

5 * 30 = 35x

150 / 35 = x

x = 30 / 7 = 4 2/7 miles


Francis ran 4 2/7 miles in one hour.

Since a fraction multiplied by the the numbers flipped (in this case, it's 12/7) gets you one, you have to multiply both 2 and 1/2 and 7/12 by 12/7 you get 4 and 4/14 miles ran in 2 hour

Which function is the inverse of f(x) = -5x-4?
tankabanditka [31]

Step-by-step explanation:

f(x) =  - 5x - 4

\:

<u>Inverse</u>

y =  - 5x - 4

x =  - 5y - 4

x + 4 =  - 5y

y =  -  \frac{(x + 4)}{5}

{f}^{ - 1} (x) =  -  \frac{(x + 4)}{5}

Solve for m pls? I'd seriously appreciate it!
Vilka [71]

Answer:

m=-1

Step-by-step explanation:

Start by multiplying both sides by 2, this will get rid of the fraction on the left side and will result in the equation 12m+6=2m-4

Then, subtract 2m from both sides, which leaves the equation as 10m+6=-4

Then, subtract 6 from both sides, this results with the equation 10m=-10

Finally, divide both sides by 10, this will result in m=-1

jane loves animals. She has an equal number of beetles, birds and spiders as pets. Apart from human legs, there is a total of 27
kherson [118]

Answer:

16.875 spiders

Step-by-step explanation:

Given

Let

B = Beetles

C = Birds

S = Spiders

So, we have:

B = C = S --- equal amounts

6B + 2C + 8S = 270 --- the legs

Required

The number of spider

Since she has an equal amount of B, C and S;

The expression can be written as:

6B + 2C + 8S = 270

6S + 2S + 8S = 270

16S = 270

Solve for S

S = \frac{270}{16}

S = 16.875

<em>The result of the solution does not represent real life situation because it it is not possible to have a fraction number of spider</em>

Each lap around the track is 1/4 of a mile. How many laps will Quadir need to jog if he wants to jog 3 1/8 miles? Helpppp
weeeeeb [17]

9514 1404 393

Answer:

  12 1/2 laps

Step-by-step explanation:

To find the number of laps, divide the distance by the distance per lap.

  (3 1/8) ÷ (1/4) = (3 1/8) × (4/1) = 3·4 +(1/8)·4 = 12 4/8 = 12 1/2

Quadir needs to jog 12 1/2 laps if he wants to jog 3 1/8 miles.
