The value of y that ensures the pool is a rectangle is 3. Option D
<h3>How to determine the value</h3>
The formula for perimeter of a rectangle is expressed as;
Perimeter = 2 ( length + width)
It is important to note that parallel sides of a rectangle are congruent, that is, they are equal.
Given the sides as;
5y + 6 = 8y -3
collect like terms
5y - 8y = -3 - 6
-3y = -9
Make 'y' the subject
y = 3
Thus, the value of y that ensures the pool is a rectangle is 3. Option D

The fraction is 15/20 and the fraction of chocolate cookies is 4/20
1/5 + 3/4 = 19/20
Answer:
The answer to your question is
Step-by-step explanation:
Inequality 1
4(3x - 4) < 32
12x - 16 < 32
12x < 32 + 16
12x < 48
x < 48/12
x < 4
Inequality 2
2x + 1 ≤ 8x + 25
2x - 8x ≤ 25 - 1
- 6x ≤ 24
x ≥ 24/-6
x ≥ - 4
