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.

Answer:

8

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

Answer: 3/4 is the answer

Step-by-step explanation:

When x is 2, y is 1.5 and when x is 4, y is 3. So, 1.5 is 3/4 of 2 and 3 is obviously 3/4 of 4.

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:

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

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.
