Which expression is equivalent to |a| < 3?1. A ≥ -3 and a ≤ 3
2. A ≤ -3 and a ≥ 3
3. a ≥ -3 or a ≤ 3
4. A ≤ -3 or a ≥ 3

This question is worth 40 points. Please help im struggling with this answer!


Answer 1


1. a ≥ -3 and a ≤ 3

I am assuming you mean to have an = sign as well

Step-by-step explanation:

|a| < =3

we get two solutions, one positive and one negative

remember to flip the inequality for the negative

a<=3 and a >= -3

The total capacity of 6 pitchers and 12 glasses is 21 liters. The capacity of a pitcher is 5 times that of a glass. Find the capacity of each glass. Give you answer in liters.


First you must set up an equation. Since there are 6 pitchers and 12 glasses you put. 6p + 12g = 21. Then they give you what p is (5g) and you plug that in and solve for g.

6(5g) + 12g = 21
30g + 12 g = 21
42 g = 21

Divide 42 on both sides to isolate the variable g. You get g = 0.5

The answer is that the capacity of each glass is 0.5 liters.

Compute the average (mean) from the data shown. (round to the nearest tenth){91, 91, 91, 97,65, 37, 41, 76, 87}
D) 75.4




Step-by-step explanation:

The mean is the average so you must add them all up and divide them by the amount of numbers there are.


(C) 75.1

Step-by-step explanation:

Add all the numbers then divide by numbers of numbers their are

91+91+91+97+65+37+41+76+ 87= 676

676/9= 75.1111111111 and it goes on forever

Tanika took a test that had 20 multiple- choice questions and 10 true/false questions. she got 9/10 of the multiple choice questions correct and she got 4/5 of the true/falsequestions coorect.
how many multiple- choices questions did tanika get correct


this is a ratio based problem.
knowing that there are 20 mc questions and she got 9/10 of them right, we can solve the problem by getting the equivalent fraction that has the same denominator as the total number of mc questions ( in this case,20)

multiplying 9/10 by 2/2, we get 18/20 and that's the answer
She got 19 answers correct.
