Which number number is equal to |-12|-|-3| ?

1 answer:

9 because the symbols around -12 and -3 so they would just become positive number 12 and 3. Subtract them and you get 9 :)

Find the solution set of the inequality:<br> -3x + 8 < 15−3x+8<15

makkiz [27]

Answer:

x=(8/3, infinity)

Step-by-step explanation:

-3x+8<15-3x+8

-3x+8<-3x+23

8<23

15-3x+8<15

23-3x<15

-3x<-8

x>8/3

Therefore, x=(8/3, infinity)

The manager of a store orders model railroad sets that cost $390 and sells them for $429. What is the mark-up, as a percentage?

Katarina [22]

Answer:

10%

Step-by-step explanation:

We have been given that the manager of a store orders model railroad sets that cost $390 and sells them for $429.

We will use markup % formula for our given problem.

$\text{Markup percentage}=\frac{\text{Selling price- Cost}}{\text{Cost}}\times 100$

$\text{Markup percentage}=\frac{429-390}{390}\times 100$

$\text{Markup percentage}=\frac{39}{390}\times 100$

$\text{Markup percentage}=\frac{1}{10}\times 100$

$\text{Markup percentage}=10$

Therefore, markup is 10% of cost.

Which inequality is graphed below

Vaselesa [24]

Answer:

$3x-2y < 6$

Step-by-step explanation:

First of all, we need to identify the equation of the line. x and y intercepts are known, so we can quickly write the line as

$\frac x 2 + \frac y{(-3)} = 1 \rightarrow 3x-2y=6$ That gives us the last two options. To solve it let's plug a convenient point - read: the origin - into the equation and see which one holds true. And since for obvious reason $3\cdot 0 -2 \cdot 0 =0 < 6$ the valid solution is the last one.
