(w^2/x−3)÷10⋅z when w=−9, x = 2.7, and z=−2/5

Answer: = − 3 /2

Precalculus, Matrix

Rearrange terms, Combine multiplied terms into a single fraction, distribute, Multiply all terms by the same value to eliminate fraction denominators, Multiply all terms by the same value to eliminate fraction denominators . Cancel multiplied terms that are in the denominator . Multiply the numbers . Add 4 to both sides of the equation . Simplify.

Divide both sides of the equation by the same term  . Simplify

Answer:

z = -3/2

Step-by-step explanation:

Our goal here is to solve -1/3 (4+z)=-5/6 for z.

Begin by multiplying both sides by 6, to eliminate the fractions:

-2(4 + z) = -5

Isolate (4 + z) by dividing both sides by -2:  4 + z = 5/2

Finally, determine z by subtracting 4 from both sides:  z = 5/2 - 8/2 = -3/2

z = -3/2

Answer:

8 gallons at $7

12 gallons at $2

Step-by-step explanation:

x gallons at $7 with the remaining (20 - x) gallons at $2 to get 20 gallons at $4

x(7) + (20 - x)(2) = 20(4)

Distribute

7x + 40 - 2x = 80

Combine like terms

5x + 40 = 80

Subtract 40 from both sides

5x = 40

Divide both sides by 5

x = 8 gallons at $7

20 - x = 12 gallons at $2

Answer:

By power of a point, AC⋅CB=DC⋅CE. That is, 12⋅12=6⋅(2R–6).

Then, R=15.

Step-by-step explanation:

Answer:

length= 35 feet and width= 10 feet

Step-by-step explanation:

You are given the perimeter of the rectangular deck is

90 feet.

2 x length + 2 x width = 90 You are also given that the deck's length is 5 feet less than 4 times it's width. That is length = 4 x width - 5

Those two equations are your system of linear equations. The second equation can be plugged into the first equation. This gives us an equation entirely in terms of width.  

2x (4 x width - 5) + 2 x width =90

Distribute the 2 though

8 x width - 10 + 2 x width = 90

Combine like terms with width.

10 x width - 10 = 90

Add 10 to both sides.

10 x width = 100

Divide both sides by 10 width = 100

Now you can plug width into your original equation for length above. Recall: length = 4 x width - 5

Length = 4 x 10 - 5

Length = 40 - 5

Length = 35

Answer:

Nonlinear.

Step-by-step explanation:

A linear graph would show a straight line in the graph (as shown in Function II). Function I, on the other hand, shows a parabola, which is a nonlinear.

Function I is a nonlinear function.

unfortunately I cant manage to understand ur question

Move to the left side, if the number is negative.

The given integers are −6 , −12 , and −16.

In math, a number line can be defined as a pictorial representation of numbers on a straight line. The numbers on a number line are placed sequentially at equal distances along its length. It can be extended infinitely in any direction and is usually represented horizontally.

Now, the given integers  −6 , −12 , and −16 can be plotted as given below.

Therefore, move to the left side, if the number is negative.

What is an expression?

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

Given that;

The expression is,

⇒ - 3.5 = - 4.6x - 5.1

Now,

Solve the expression as;

The expression is,

⇒ - 3.5 = - 4.6x - 5.1

Solve for x as;

⇒ - 3.5 + 5.1 = - 4.6x

⇒ 1.6 = - 4.6x

⇒ -4.6x = 1.6

⇒ x = 1.6 / - 4.6

⇒ x = - 16/46

⇒ x = - 8/23

Thus, The solution of the expression will be;

⇒ x = - 8/23

Answer:

No Solution

Step-by-step explanation:

If we solve for the equation, we get a statement that isn't true.

9x + 7 = 9x - 4

-9x        -9x

----------------------

7 = - 4

*subtract 9x from both sides*  

We know that 7 ≠ -4, so there aren't any solutions to this problem.

Step-by-step explanation:

First, add the values inside the radical

488+24 = 512

[tex]\sqrt[3]{512}[/tex] = x

This means that: [tex]x^{3}[/tex] = 512

Therefore, x must be equal to 8.

[tex]\sqrt[3]{512}[/tex] = 8
