I need to drink 8 2/4 cups of water and 2 1/5 cups milk every day. How much fluid do I have to drink?

lidiya [134]

Answer:

The total fluid you have to drink is 10 7/10 = 10.7 cups.

Step-by-step explanation:

The daily requirement of water = 8 2/4 cups

Now, $8 \frac{2}{4} = 8+ \frac{2}{4} = 8+ 0.5 = 8.5$

or, the daily water requirement = 8.5 cups

The daily requirement of milk = 2 1/5 cups

Now, $2 \frac{1}{5} = 2+ \frac{1}{5} = 2+ 0.2 = 2.2$

or, the daily milk requirement = 2.2 cups

So, The total fluid needed = Cups of (Water + Milk) needed

= 8.5 cups + 2.2 cups

= 10.7 cups

Also, $10.7 = 10 + 0.7 = 10 + \frac{7}{10} = 10\frac{7}{10}$

Hence, the total fluid you have to drink is 10 7/10 cups.

What is -4R-2r+5 as a simpler exspression

enyata [817]

$\sf-4R-2r+5$ is already in simplest form.

But if you meant to say $\sf-4r-2r+5$ , we would combine the first two terms.

Adding/subtracting like terms is the same as adding/subtracting whole numbers.

$\sf-4-2=-6$

Therefore:

$\sf-4r-2r=-6r$

Which gives us:

$\boxed{\sf-6r+5}$

Find the volume of the sphere .<br> (Geometry)

asambeis [7]

Answer:

V = 32/3 pi

Step-by-step explanation:

The volume of a sphere is given by

V= 4/3 pi r^3

We know the radius is 2

V = 4/3 pi (2)^3

V = 4/3 pi (8)

V = 32/3 pi

Need to solve this problem in steps 5(2x+6)=-4(-5-2x)+3x

Dovator [93]

Answer:

Simplifying

5(2x + 6) = -4(-5 + -2x) + 3x

Reorder the terms:

5(6 + 2x) = -4(-5 + -2x) + 3x

(6 * 5 + 2x * 5) = -4(-5 + -2x) + 3x

(30 + 10x) = -4(-5 + -2x) + 3x

30 + 10x = (-5 * -4 + -2x * -4) + 3x

30 + 10x = (20 + 8x) + 3x

Combine like terms: 8x + 3x = 11x

30 + 10x = 20 + 11x

Solving

30 + 10x = 20 + 11x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-11x' to each side of the equation.

30 + 10x + -11x = 20 + 11x + -11x

Combine like terms: 10x + -11x = -1x

30 + -1x = 20 + 11x + -11x

Combine like terms: 11x + -11x = 0

30 + -1x = 20 + 0

30 + -1x = 20

Add '-30' to each side of the equation.

30 + -30 + -1x = 20 + -30

Combine like terms: 30 + -30 = 0

0 + -1x = 20 + -30

-1x = 20 + -30

Combine like terms: 20 + -30 = -10

-1x = -10

Divide each side by '-1'.

x = 10

Simplifying

x = 10
