200 books x 30 boxes = 6000 books
6000 books x 20 shipping crates = 120,000 books
Just keep multiplying

What two numbers are 7 units from 0 on a number line?

Neporo4naja [7]

3 is only 3 spots away from 0, so A is not the answer.

8 is 8 spots away from 0, so B is not the answer.

9 is 9 spots away from 0, so D is not the answer.

The answer is C, as -7 and 7 are both 7 spots away from 0 in the number line.

Suppose the scale factor you will use to enlarge the map is 5:1. What is the approximate area of the park in your enlarged drawi

slamgirl [31]

Answer:

525

Step-by-step explanation:

If the area of the map is 21 and the scale factor is 5:1, both of the dimensions of the flat park are multiplied by 5. If both dimensions are multiplied by 5, then the area is multiplied by (5*5)=25 times. 25*21=525. Hope this helps!

Which number line represents the solution set for the inequality 2x – 6 ≥ 6(x – 2) + 8? A number line from negative 1.5 to 1.5 i

Nuetrik [128]

Answer:

A point is at negative 0.5 and a bold line starts at negative 0.5 and is pointing to the left.

The number line in Option C.

Step-by-step explanation:

We are given an inequality.

$2x - 6 \geq 6(x - 2) + 8$

We have to find the number line that shows the solution for the given inequality.

If we solve the given inequality,

$2x - 6 \geq 6(x - 2) + 8\\\Rightarrow 2x - 6 \geq 6x - 12 + 8\\ \Rightarrow 2x - 6 \geq 6x - 4\\\Rightarrow 2x - 6x \ geq -4 + 6\\\Rightarrow -4x \geq 2\\\Rightarrow -x \geq 0.5\\\Rightarrow x \leq -0.5$

is the required solution of the given inequality.

Thus, if we want to plot or show this solution on a number line, then we need to we need to mark the point -0.5 and all the numbers less than -0.5

A point is at negative 0.5 and a bold line starts at negative 0.5 and is pointing to the left.

This s represented in Option C.

What is 2x2+11x-15=0

Elanso [62]

$2x^{2} + 11x - 15 = 0$

Use the quadratic equation:
$x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}$
$= \frac{-11 \pm \sqrt{121 - 4(2)(-15)}}{4}$
$= \frac{-11 \pm \sqrt{121 + 120}}{4}$
$= \frac{-11 \pm \sqrt{241}}{4}$

$\therefore x = \frac{-11 + \sqrt{241}}{4}$
or $x = \frac{-11 - \sqrt{241}}{4}$
