Answer:

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

A pizza had 9/10 left before Lucas ate 4/5 of the pizza. How much pizza is left over
Norma-Jean [14]
1/10 is left.

Explanation:

First we need to find a common denominator. Since 5×2=10, if we multiply 4/5 by 2/2, we will be able to subtract that from 9/10.

4/5×2/2= 8/10. Then if we subtract that from the 9/10 left of the pizza, we get 1/10, the amount remaining.

Hope this helps :)
