Put the exponent aside and simplfy the base by pulling out like factors :
-2xy3z-2 = -2 • (xy3z+1)
Remember the 4th law of exponents : (a • b)m= am• bm
Retract the exponent and apply the 4th law to the simplified base: ( -2 • (xy3z+1) )3 = (-2)3 • (xy3z+1)3

Put the exponent aside, try to factor xy3z+1
Theory : A sum of two perfect cubes, a3 + b3 can be factored into :

Proof : (a+b) • (a2-ab+b2) =
a3-a2b+ab2+ba2-b2a+b3 =
a3+(a2b-ba2)+(ab2-b2a)+b3=
a3+0+0+b3=

Check : x 1 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cubes
Dividing exponents:

The system of equations has no solution.
NO SOLUTION!
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}y=-\frac{1}{2}x+4\\ x+2y=-8\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y+\frac{1}{2}x=4\\ 2y+x=-8\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}y+\frac{1}{2}x=4\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y+x=8[/tex]

A shirt marked $320.00 was sold at a discount of 5%. What was the selling price?
Answer:
304
Step by step:
Using your calculator 5% of 320 is 16.
Since it was a discount, you subtract 16 since you're marking it down.
320-16=304
304 is your answer
How do I know? Well, there it takes 20+20+20+20+20 to equal a hundred. We can do this same math for this problem. 16 x 20 is 320
Answer:
$304.00
that is really freaking expensive shirt lol.
i thought you said shlt, not shirt lol
anyway...
Step-by-step explanation:
320 times 0.05
(don't make the mistake of 0.5 that is 50%, not 5%. )
320*0.05= 16
subtract it

20 feet of lumber cost $138.40. what is the cost per foot
Answer: $6.92
Step-by-step explanation: Whenever you see the word per in a math problem, that means division. So right now, you could set up an equation that looks like this. 20L=130.40 (let L mean cost per foot of lumber). If you want to find the cost per foot you need have 1L or just L on one side of the equation. Well, the easiest way to do that would be to divide by 20 on both sides. And that would get you L= 6.92. And since L means the cost per foot of lumber, that cost would be $6.92. Hope this helps!

The class has 12 girls and 16 boys. What is the ratio of total students to boys in simplest form?
Answer:
7:4
Step-by-step explanation:
total students = 28
so ratio 28:16
which will be reduced to14:8
then 7:4
boys : girls
= 16 : 12
= 16/12
[After simplifying]
= 4/3
So, ratio of boys to girls in simplest form => 4 : 3

How many yards are in 96 inches by 30 feet?
Answer:30 x 96 feet = 10 x 32 yards
Step-by-step explanation:Convert 30 x 96 feet to yards
To convert length x width dimensions from feet to yards we should multiply each amount by the conversion factor. One foot equals 0.333333 yards, in order to convert 30 x 96 feet to yards we have to multiply each amount of feet by 0.333333 to obtain the length and width in yards. In this case to convert 30 x 96 feet into yards we should multiply the length which is 30 by 0.333333 and the width which is 96 by 0.333333. The result is the following:
30 x 96 feet = 10 x 32 yards
Definition of foot
A foot (symbol: ft) is a unit of length. It is equal to 0.3048 m, and used in the imperial system of units and United States customary units. The unit of foot derived from the human foot. It is subdivided into 12 inches.
Definition of yard
A yard (symbol: yd) is a basic unit of length which is commonly used in United States customary units, Imperial units and the former English units. It is equal to 3 feet or 36 inches, defined as 91.44 centimeters.
Meters to yards formula and conversion factor
To calculate a foot value to the corresponding value in yards, just multiply the quantity in feet by 0.333333 (the conversion factor).
Meters to yards formulae
yards = feet * 0.333333
The factor 0.333333 is the result from the division 1 / 3 (yard definition). Therefore, another way would be:
yards = feet / 3
Using our feet to yards converter you can get answers to questions like:
- How many yards are in 30 x 96 feet?
- 30 x 96 feet is equal to how many yards?
- How to convert 30 x 96 feet to yards?
- What is 30 x 96 feet in yards?

7/12 divided by 5/9 in its simplest form
Answer: 1 and 1/20th. Don’t know if it’s in simplest form tho
Step-by-step explanation:
7/12 divided by 5/9, in its simplest form, is 21/20.
Given that we need to divide 7/12 by 5/9,
The reciprocal of a fraction is obtained by interchanging the numerator and the denominator.
So, to simplify 7/12 divided by 5/9, we multiply 7/12 by the reciprocal of 5/9:
7/12 ÷ 5/9 = 7/12 × 9/5
Next, we multiply the numerators and denominators:
(7 × 9) / (12 × 5) = 63/60
To simplify this fraction further, we can divide both the numerator and denominator by their greatest common divisor (GCD), which is 3:
63/60 = (63 ÷ 3) / (60 ÷ 3) = 21/20
Therefore, 7/12 divided by 5/9, in its simplest form, is 21/20.

Jasmine created a scale drawing of her room. She used a scale of 1 in:3 feet. The drawing is 8 inches long by 6 inches wide. What is the area of the room in square feet?
Answer:
The area of the room is 432 square feet
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The scale drawing of the room is 1 inch: 3 feet
→ That means each 1 inch in the drawing represents 3 feet in real
∵ The drawing is 8 inches long by 6 inches wide
∴ The drawing length of the room = 8 inches
∴ The drawing width of the room = 6 inches
→ By using the ratio method
→ inches : feet
→ 1 : 3
→ 8 : L
→ 6 : W
→ By using the cross multiplication
∵ 1 × L = 8 × 3
∴ L = 24
∴ The actual length of the room is 24 feet
∵ 1 × W = 6 × 3
∴ W = 18
∴ The actual width of the room is 18 feet
Use the formula of the area of the rectangle to find the area of the room
∵ Area of rectangle = length × width
∴ Area of the room = 24 × 18
∴ Area of the room = 432 feet²
∴ The area of the room is 432 square feet
