Answer: a) (5 - 7)²
<u>Step-by-step explanation:</u>
g(x) = x^2 h(x) = x - 7
h(5) = 5 - 7
g(h(5)) = g(5 - 7) = (5 - 7)² <em>Replace the x in g(x) with (5 - 7)</em>

Answer:
3x + x + 100° = 180°
⇔ 4x = 80°
⇔ x = 20°
Step-by-step explanation:
Let n represent the number. You require
7n - 2n = 55
5n = 55 . . . . . . collect terms
n = 11 . . . . . . . divide by 5
The number is 11.

Step-by-step explanation:
Using the table of 150 students, we can configure probabilities.
18 students participate in tennis, so the probability of a student participating in tennis is 18/150, or 3/25 simplified.
45 students participate in football, so the probability of a student participating in football is 45/150, or 3/10 simplified.
12 students participate in gymnastics, so the probability of a student participating in gymnastics is 12/150, or 2/25 simplified.
9 students participate in volleyball, so the probability of a student participating in volleyball is 9/150, or 3/50 simplified.
