Answer:
I do't know how to solve this.
Step-by-step explanation:
The answer is A! If 1/3 is gone, there’s 2/3 left. To find how much 2/3 is, you would multiply 80 by 2/3
-2<x<3 | *2
-4<2x<6 | +7
3< 2x+7< 13
3<10<13
The answer is C
Answer and explanation:

(x + 6)(x + 7)
List the multiples of 42
42: 1 2 3 6 7 14 21 42
Then see which of the multiples add up to 13
1 x 42 = 42 --> 1 + 42
13
2 x 21 = 42 --> 2 + 21
13
3 x 14 = 42 --> 3 + 14
13
6 x 7 = 42 --> 6 + 7 = 13
Answer:
{-4 = 7, 5 = 5} = {False, True}
