Answer:

A: 5 behind the line

Step-by-step explanation:

You can make an equation: 8 - 6 - 4 - 9 + 6

Then you can solve it a little at a time:

8 - 6 = 2

2 - 4 = -2

-2 - 9 = -11

-11 + 6 = -5

Negative 5 is the same thing as 5 behind the line.

Answer:

A. Five behind the line.  

Step-by-step explanation:

We can use a number line (see below) to solve this problem.

Start at 0.

Jump eight units to the right.

Then jump in succession six, four, and nine units to the left.

Finally, jump six units to the right.

You end up five units to the left of zero (five squares behind the line).

Mathematically,

0 + 8 - 6 – 4 - 9 + 6 = -5

The diameter of your bicycle wheel is 34 inches. How far will you move in one turn of your wheel? What is the distance covered i
irga5000 [103]
In one turn of the wheel, you will move the circumference of the wheel. To find the circumference, you just do π × diameter, so π × 34 = 106.8 inches. In 5 turns, you will just go 5 times the circumference, so you multiply by 5 to get 534.1 inches. I hope this helps!

If B is the midpoint of AC and AB = 4x + 14 and BC = x + 20, determine how long AC is.
Serhud [2]

Answer:

44 units

Step-by-step explanation:

Since B is the mid-point of AC

AB=BC

or,4x+14=x+20

or, 4x-x=20-14

or 3x=6

or,x=6/3=2

AC=AB+BC

= 4x+14+x+20

= 4(2) + 14 +2 +20

= 8+14+22

=44 units

Indicate all possible values for the variable in each of the expressions: sqrt(2x+2)+sqrt(6-4x)
IrinaK [193]

Answer:

<u>Given expression:</u>

  • \sqrt{2x+2}+\sqrt{6-4x}

<u>The first root is valid when:</u>

  • 2x + 2 ≥ 0 ⇒ 2x ≥ - 2 ⇒ x ≥ - 1

<u>The second root is valid when:</u>

  • 6 - 4x ≥ 0 ⇒ 4x ≤ 6 ⇒ x ≤ 1.5

<u>So the variable x can get values within interval:</u>

  • -1 ≤ x ≤ 1.5 or
  • x = [-1, 1.5]
