Charlie had a full bottle of water. He drank 1/4 of the water in the morning. He drank 2/5 of the water with lunch. How much of
12345 [234]

Answer:

7/20

Step-by-step explanation:

first of all you have to put the two fractions on the same denominators

1/4 (multiply by 5) and you will get 5/20

2/5(multiply by 4) and you will get 8/20

we have to add 5/20 and 8/20 that gives us 13/20

13/20 is the amount he drank

20/20 - 13/20 =7/20

7/20 is the amount of water left that Charlie has left

ILL GIVE BRAINLIEST IF ITS RIGHT
Vesna [10]

Answer: 6

Step-by-step explanation:

Slope is found by doing:

\frac{y_1 - y}{x_1 - x}

(x1 and y1 must be from the same ordered pair and x and y must be from the same ordered pair, however point (x1,y1) and (x,y) can be used interchangeably)

Let us say that (x1,y1) is (3,18)

And (x,y) is (5,30)

\frac{18 - 30}{3 - 5} = \frac{-12}{-2} = 6
