Answer:
- 4 < x ≤ 7
Step-by-step explanation:
Given
- 10 ≤ - 5x + 25 < 45 ( subtract 25 from all 3 intervals )
- 35 ≤ - 5x < 20
Divide all 3 intervals by - 5, reversing the inequality signs as a consequence.
7 ≥ x > - 4
Hence - 4 < x ≤ 7
Step-by-step explanation:
In total there is 6 cups of soup.
So lets put that in /8 form
48/8 and do the same to the other 27/8
So when you see it takes 27/8 for one you know she can only do one full serving.
21/8 is what's left
So 2 5/8 is left
She is 6/8 off of one more serving
I'm sorry this is all I can do. I hope you can use this info to answer

Answer:
see explanation
Step-by-step explanation:
Since the pentagon has one line of symmetry. This will be a vertical line through C, thus
CD = BC = x + 1 and ED = AB = 2x + 3
Perimeter = AE + ED + DC + CB + BA
= 4x + 2x + 3 + x + 1 + x + 1 + 2x + 3 = 10x + 8
Perimeter is given as 21, thus
(b)
10x + 8 = 21 (subtract 8 from both sides )
10x = 13 ( divide both sides by 10 )
x = 
= 1.3
