Answer:

(8, 11π/6)

Step-by-step explanation:

8 7 / 8 + 9 13 / 16 what is this in a mixed number.

FinnZ [79.3K]

Answer:

18 and 11/16

Step-by-step explanation:

I converted the two numbers into improper fractions which leaves me with

71/8+157/16

I thenn made sure I had common denominators, which means I need to multiply the first number by 2/2 and I'm left with:

142/16+157/16

I can now add the 2 numbers together and I get:

299/16

now we just need to convert the number into a mixed number by dividing, and I am left with:

18 and 11/16

Mallory needs to go to the airport. It takes her 120 minutes to get there by car. This is 3 times the time it takes by

seraphim [82]

It will take Mallory 40 minutes to get to the airport by train.

Step-by-step explanation:

Given,

Time taken by car = 120 minutes

Time taken by train = t

According to given statement;

Time taken by car = 3 times time taken by train

$120=3t$

Dividing both sides by 3

$\frac{120}{3}=\frac{3t}{3}\\40=t\\t=40$

It will take Mallory 40 minutes to get to the airport by train.
