Answer:

[tex]-1^{3}[/tex]

Step-by-step explanation:

Answer:

Simplified -1^3, Solution: -1

Step-by-step explanation:

Since you have to multiply -1*-1*-1 then the answer would be -1. Simply because when simplifying the equation -1*-1 is 1 (remember that when multiplying two negatives it adds to a positive). Then you multiply 1*-1 which comes out to be -1 as the answer. I hope this helps, if you need further explanation please comment below.

Answer:

z³ = 64

z³=4³

since power is equal, base will be same

z=4

Step-by-step explanation:

The value of z in the expression is,

⇒ z = 4

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Expression is,

⇒ z³ = 64

Now, We can simplify the expression as;

⇒ z³ = 64

Take cube root both side,

⇒ z = ∛64

⇒ z = ∛4³

⇒ z = 4

Thus, The value of z in the expression is,

⇒ z = 4

Answer:

B: $2.50

Step-by-step explanation:

Step 1: form an equation

126 = 12(8 + x)

Step 2: isolate the x

126/12 = 8 + x

126/12 - 8 = x

Step 3: solve

10.5 - 8 = x

2.5 = x = raise per hour

Answer:

(12 + 3x)x

Step-by-step explanation:

(12 + 3)x = 12x + 3x = 15x

(12 + 3x)x = 12x + 3x²

15x

12x + 3x = 15x

They all equal 15x except for (12 + 3x)x

Answer:

15.81

Step-by-step explanation:

The full answer is 15.8113883 but since you want it rounded to two decimal places the second 1 in 15.8113883 makes the number round to 15.81

Step-by-step explanation:

Hey there!!!!

Given,

Angle r and angle s are supplementary angle.

And angle r = 120°.

Now, we have,

supplementary angle's sum is always 180°.

So, angle r + angle s = 180°.

or, 120°+ angle s = 180°

Therefore the measure of angle s is 60°.

Step-by-step explanation:

(√3-1)/2 and (√3+1)/2

the quadratic equation:

x²-(sum of the root)x +product of the roots

x²-((√3-1)/2 + (√3+1)/2)x+((√3-1)/2) )(√3+1)/2)

x²-(2√3/2)x+ (3-1)/4

x²-√3 x+1/2

x²-x√3 +1/2

Answer: 60

Step-by-step explanation:

Since AB and BC creates AC, we can add them together to find x, then use that to find the value of BC.

8x+9+6x+6=141                  [combine like terms]

14x+15=141                          [subtract both sides by 15]

14x=126                               [divide both sides by 14]

x=9

Now that we have found the value of x, we can plug that into BC.

6(9)+6                                 [multiply]

54+6                                   [add]

60

Now, we know the length of BC is 60.

Answer:

shade the bottom part.

Step-by-step explanation:

I'm pretty sure because if y is less than -x -1 , then everything on the bottom is less than that? Sorry if it is not correct.

Answer:

Step-by-step explanation:

Let your number be X. To increase X by 40% we can multiply it by 1.4, let's call this new number Y.

So Y = X * 1.4

Now to decrease Y by 40% we can multiply it by 1 - .4 = .6. Lets call this new number C.

So C = Y *.6 = (X * 1.4) * .6 = X * (1.4 * .6) = X * .84.

Therefore, C = .84 * X.

So we can see C is 84% of X, or 16% less than X.

Thus, if you increase a number by 40% then decrease it by 40%, the net percentage is -16% .

      Final result in terms of 'x' will be → 0.75x

Let the number = x

As per first statement → "A number 'x' is decreased by 40%"

Algebraic expression for the statement → (x - 40% of x)

                                                                  → (x - 0.4x)

                                                                  → 0.6x

Second statement → "Then increased by 25%"

Algebraic expression for the statement → (0.6x + 25% of 0.6x)

                                                                  → [tex](0.6x+\frac{25}{100}\times 0.6x)[/tex]

                                                                  → [tex](0.6x+0.15x)[/tex]

                                                                  → [tex]0.75x[/tex]

           Therefore, final result in terms of x will be (0.75x).

Answer:

x = 0

Step-by-step explanation:

9(2x+1) < 9x - 18

Distribute the 9 through

18x + 9 < 9x - 18

Get like terms on the same sides

9x < -27

Divide both sides by the value in front of the x

x < -3

Answer:

63 miles

Step-by-step explanation:

Bonnie ran a total of 18 miles over the course of 2 track practices. How many miles would Bonnie have run after 7 track practices?

2 track practices = 18 miles

7 track practices = y miles

Cross Multiply

2 track practices × y miles = 18 miles × 7 track practices

y miles = 18 miles × 7 track practices/ 2 track practices

y miles = 63 miles.

Therefore, Bonnie will have run 63 miles after 7 track practices
