May I introduce you to

The world's most decorated zoo

For everything you wish was make-believe

Oh, buddy did you know

You could shake hands with a demon

If you wanna take that dare, so be it

You could lose an arm or a leg so easy here

So let me give you a scenario

And don't you tell a soul

It's only hypothetical

Imagine all your nightmares

Contained in a single glorified reformatory

Where nothing ever gets out

Straitjackets have been worn out

1. Translate the variable expression into a word phrase: 4b – 2

nevsk [136]

1. 4b - 2 : the product of 4 and a number (b) decreased by 2

2. the sum of 15 and 4 times a number......15 + 4x

3. 8 fewer boys then girls...how many boys.......b = g - 8

4. It will be less then 1 because of the negative exponent....a negative exponent will mean the number is less then 1...I dont really know how else to explain it.

5. Doug is twice Anna's age...doug is 34 years old
I dont know the 5 step plan...but I am putting what I do know

d = doug's age
a = anna's age

d = 2a
d = 34

34 = 2a
34/2 = a
17 = a....so anna is 17

check..
d = 2a
d = 2(17)
d = 34 (correct)

Step-by-step explanation:

Add both prices too get 165

Then use the equation =

cross multiply to get 150x=16500

Divide 16500 by 150 to get x alone

x= 180

Solve x2 – 64 = 0. Isolate x2: x2 = 64 Apply the square root property of equality: Isolate the variable: x = x =

dybincka [34]

Solve the equation by isolating the variable you're solving for on one side of the equation and get everything on the opposite side.

$x^2 - 64 = 0$

The x variable is being square and is being subtracted by 64.
Find the inverse of all of these operations.

First, get rid of the subtraction operation. The inverse of subtraction is addition.

Add 64 to both sides of the equation.

$x^2 - 64 + 64 = 0 + 64 \\ x^2 = 64$

Now the variable x is only being squared. Reverse this operation by using the inverse of exponents.

Take the square root of both sides.

$\sqrt{x^2} = \sqrt{64} \\ x = 8$

So, x is equal to 8.
