The solution to an absolute value inequality is shown on the graph below. What is another way to show the solution?
svetlana [45]

Answer:

(-3,2)

Step-by-step explanation:

From the number line graph we can see that there is a open circle at -3

and an open circle at 2.

The shaded part lies between -3  and 2

So we can write inequality form as -3<x<2.

Interval form

If we have open circle then we use parenthesis when we write it in interval notation. we have open circle at -3  and 2

So interval notation is (-3,2)

Kevin has mowed 40% of the lawn. If he has been mowing for 20 minutes, how long will it take him to mow the rest of the grass?
Katen [24]
It will take 30 minutes more for remaining grass. As he mowed 40% in 20 minutes, it shows that he mows twice percentage of grass in the time calculated in minutes. So it will take 30 minutes for remaining 60% grass.

Write and evaluate two equivalent numerical expressions that show Distributive Property of Multiplication
Ainat [17]

Answer:

2(x+5) = 2x+10

Step-by-step explanation:

I'm assuming you can use any possible combination of two equivalent numerical expressions for your question.

2(x+5) = 2x+10

2 times x is 2x. 2 times 5 is 10. So, you get 2x+10
