Simplify the expression. -216) + 3(5 – 4 x 2)

masya89 [10]

Answer:

Step-by-step explanation:

If it's (-216):

(-216) + 3(5 - 4 x 2)

(-216) + 3( -3)

(-216) -9

-225

If it's -2(16):

-2(16) + 3(5 - 4 x 2)

-2(16) + 3(-3)

-32 - 9

Find the area of a cube. 5in, 5in, 5 in

Verizon [17]

Answer:

150in²

Step-by-step explanation:

The surface area of a cube is given by the following equation where s is the length of a side:

$A=6s^2$

So, in this case, s is equal to 5:

$A = 6(5)^2 = 6(25)=150in^2$

2/3 b + 5 =20 - b solve for b

Wittaler [7]

Answer:

$b = 9$

Step-by-step explanation:

$\frac{2}{3} b + 5 = 20 - b$

In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.

$\frac{2}{3} b + 5 - 5 = 20 - b - 5$

Simplify.

$\frac{2}{3} b = 15 - b$

Add b to both sides.

$\frac{2}{3} b + b = 15 - b + b$

Simplify.

$\frac{2}{3} b + b = 15$

Multiply everything by 3 to remove the fractions.

$3(\frac{2}{3}b+b) = 3(15)$

Simplify.

2b + 3b = 45

Simplify.

5b = 45

Divide 5 from both sides.

5b ÷ 5 = 45 ÷ 5

Simplify.

b = 9
