Tristan rode his bike 3 2/3 miles on saturday he rode 1 4/5 mi on sunday how many more miles did he ride on saturday then on sunday a.1 3/15 miles b.1 3/5 c.1 13/15 d.2 13/15

c. 1 13/15

Step-by-step explanation:

The best way to find out how much more Tristan rode his bike would be to subtract both of his distances together.

Saturday =

Sunday =

Now we actually have two different fractions with different denominators.

We can solve this first by converting the mixed numbers into improper fractions.

Now how did I do that?

First we take the denominator and multiply it to our whole number, then add the product to the numerator.

Let's proceed to the next mixed fraction.

We are then left with:

Since we cannot subtract them directly because they have different denominators, we need to find the LCD of both denominators.

Now that they have similar denominators, we can then proceed to subtract them to each other.

4096 bacteria

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
