The inequality to determine the minimum number of hours he needs to practice on each of the two days will be x >= (5/3)/2.
<h3>How to calculate the inequality?</h3>
Let the minimum number of hours to practice be represented by x.
She had already used 5 1/3 hours. The remaining hour will be:
= 7 - 5 1/3
= 1 2/3 hours.
Therefore, the inequality to represent the situation will be:
= x >= (5/3)/2

Answer:
80°
Step-by-step explanation:
The sum of the interior angles in a hexagon is 720°. This means that:
y + (2y - 20) + (2y - 20) + y + (2y - 20) + (2y - 20) = 720° - we can simplify this
10y - 80 = 720° - now, add 80 to both sides
10y = 800 - finally, divide both sides by 10
y = 800 ÷ 8 = 80°
