1. The power is being multiplied by the three on the outside of the parentheses. Both powers are being multiplied by 1.

2. 7^30

3. 54^3

4. Yes, because the communitive property you can multiply 5 and 4 and you get 20, if you reverse it 4 times 5 you still get the product of 20.

Answer:

400 people

Step-by-step explanation:

15 = 12

500 = x

Cross multiply

15x = 12 × 500

Divide both sides by 15

[tex]\frac{15x}{15}[/tex] = [tex]\frac{12 * 500}{15}[/tex]  (* means multiplication if you do not know)

[tex]\frac{12 * 500}{15}[/tex] = 100 × 4= 400 people

Answer:

10

Step-by-step explanation:

All you're doing is [tex]\frac{5}{8}[/tex] ×[tex]\frac{16}{1}[/tex] or   [tex]\frac{5}{8}[/tex] ×[tex]16[/tex]

-

[tex]\frac{5}{8}[/tex] ×[tex]\frac{16}{1}[/tex]

so 5 × 16 = 80

and

8 × 1 = 8

The fraction becomes

[tex]\frac{80}{8}[/tex]

then you simplify ( in this case divide by the botton number/denominator) to get :

Answer: Q1: D. Distribute 3 through the parenthesis

Step-by-step explanation:

As for the second question, I am not sure how to begin. Sorry

Answer:

For the first question: 3(p - 3) = 2p + 7, the first step would be to distribute 3 to both terms in the parentheses

For the second question:

6n + 11 = -7 + 3n

-3n               -3n

3n + 11 = -7

      -11    -11

3n = -18

3n/3 = -18/3

n = -6

Check:

6(-6) + 11 = -7 + 3(-6)

-36 + 11 = -7 + -18

-25 = -25, since these match n definitely equals -6

Answer:

x=-4

Step-by-step explanation:

You have to do all this math to isolate the variable, so, first,

You have to use the opposite sign of negative 3, which is positive 3, and add on both sides!

Then, you isolate the variable by dividing -2 on both sides, which is...

-4!

Answer:

x=10

Step-by-step explanation:

1. Do the inverse and add 8 to both sides to get 3x-2x=10

2. Combine like terms 3x-2x= 1x which simplifies to x

Answer:

18

Step-by-step explanation:

If you take a look at it, its quite similar to the example

Since they are using the same dimensions (1.5) you multiply 1.5 x number x 1.5 again

1/8 as a reciprocal is 8

so you do 1.5 x 8 x 1.5 which gives you 18

Answer: Real, irrational

Step-by-step explanation:

Real because it is an actual measurement. Irrational because π can't be expressed as a fraction. Not an integer because integers are whole numbers.

The correct classification is -Real, Irrational

Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.

Irrational numbers are real numbers that cannot be represented as a simple fraction. These cannot be expressed in the form of ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.

Given number: 7* pi

Here, 7 is the real number.

But pi is real but not rational number.

pi is an irrational number.

Hence, the correct classification of 7 pi is Real, Irrational.

Answer:

A triangular prism is 1/2 the volume of a rectangular prism with the same dimensions.

V = BH (Base x Width) of a triangular its 1/2BH

The base is 10 x 5, 50 is the base.

The height is 6, and that would be 300 / 2 since it's triangular so its 150 inches squared for one. Since there are 2.

The total volume is 300 inches squared.

x = -8 and y= 8

(-8,8) is the answer

Answer:

(2,4) (-4,16)

Step-by-step explanation:

Subtract  2 x  from both sides of the equation.

y = 8 − 2 x

Substitute  8 − 2 x  for  y  into  x ^2 − y = 0  then solve for  x .

x = 2 , − 4

Substitute  2  for  x  into  x 2 − y = 0  then solve for  y .

y=4

Substitute  − 4  for  x  into  x 2 − y = 0  then solve for  y .

y=16

Equation form

x = 2 , y = 4

x = − 4 ,  y = 16
