3x+2x+7=8x+8 solve for x

Mathematics

Kryger [21]3 years ago

Answer:

x = \frac{-1}{3}

Step-by-step explanation:

The bold side will be the "first side" and the italics will be the "second side."

3x + 2x + 7 = <em>8x + 8</em>

First, you add the variables from the first side of the equal sign together.

3x + 2x = 5

Now the equation becomes: 5x + 7 = <em>8x + 8</em>

Then you're going to take the 7 from the first side and subtract it from the 8 on the second side.

8 / 5 x + 1

8-7 = 1

Now the equation becomes: 5x = <em>8x + 1</em>

Subtract 8x from both sides

-3x = <em>1</em>

Divide both sides by -3

x = \frac{-1}{3}

The base of a parallelogram is 18 inches longer than three times the height. The area of the parallelogram is 216 square inches.
nordsb [41]

Answer:

12 inches

Step-by-step explanation:

Let b represent the base

h represents the height

area of the parallelogram = base * height = 216 square inches

From the question'

b = 18 + 3h

Slot in the value of b

216 = (18 + 3h) * h

expand

216 = 18h + 3h^2

subtract 216 from both sides

0 = 18h + 3h^2 - 216

rearrange

3h^2 + 18h - 216 = 0

divide through by 3

h^2 + 6h - 72 = 0

Now, lets solve!

h^2 + 6h - 12h - 72 = 0

h( h + 6 ) - 12(h + 6) = 0

(h - 12) (h + 6) = 0

h - 12 = 0

h = 12

and

h + 6 = 0

h = - 6

Taking the positive value of h

Hence, the height is 12 inches

Lets check

when h = 12 inches

Area of the parallelogram = 18* 12 = 216 square inches     .... correct

when h = -6inches

A = 18 * -6 ≠  216 square inches

So height is 12 inches

Helppppp..... evaluate 3^-3=
elixir [45]

ANSWER

The answer is

B

\frac{1}{27}

EXPLANATION

The given expression is

{3}^{ - 3}

Use the negative index property;

{a}^{ - m}  =  \frac{1}{ {a}^{m} }

We apply this property to get:

{3}^{ - 3}  =  \frac{1}{ {3}^{3} }

This gives us:

{3}^{ - 3}  =  \frac{1}{3 \times 3 \times 3 }

{3}^{ - 3}  =  \frac{1}{27}

The correct option is B.
