How do you do 1/4 (16x+20)-7x

1 answer:

Ira Lisetskai [31]3 years ago

Distribute the 1/4:
1/4(16x) + 1/4(20) - 7x

Do the multiplication:
1/4(16x) = 16x/4 = 4x
1/4 (20) = 20/4 = 5

Now you have:
4x + 5 - 7x = 0

Combine like terms (4x and -7x):
-3x + 5 = 0

Subtract 5 from both sides:
-3x = -5

Divide by -3:
x = -5/-3 = 5/3

Answer:
x= 5/3

A thermos in the shape of a cylinder is filled with coffee. The height of the cylinder is 12 inches and its radius is 2 inches.

emmainna [20.7K]

Answer:

Option C is correct

Volume of coffee in the thermos is, 150.8 cubic inches

Step-by-step explanation:

Volume of the cylinder is given by:

$V =\pi r^2h$

Where

V is the volume of the cylinder

r is the radius

h is the height of the cylinder respectively

As per the statement:

A thermos in the shape of a cylinder is filled with coffee.

the height of the cylinder is 12 inches and its radius is 2 inches

⇒ h = 12 inches and r = 2 inches.

Substitute the given values and use $\pi = 3.14$ in [1]

then;

$V =3.14 \cdot 2^2 \cdot 12$

$V =3.14 \cdot 48$

Simplify:

V ≈150.8 inches.

Therefore, the volume of coffee in the thermos is, 150.8 cubic inches
