=
=
Solving the like terms together, we have
=
which is the required simplified form of the given expression.
Hence, option D is correct.
Answer:
Step-by-step explanation:
The two base angles are equal.
The vertex angle is 8x
The two base angles are 5x + 5x
The sum of all three angles = 180 degrees (all triangles make 180 degrees when their interior angles are added).
5x + 5x + 8x = 180
18x = 180
x = 180/18
x = 10
Therefore the vertex angle is 8*10 = 80 degrees
One of the base angles = 10* 5 = 50 degrees
The other base angle = 50 because the triangle is isosceles.
There are 5 terms.
A term is a coefficient and a variable put together.
Answer: 360 - 44 - 80 = 236
236 ÷ 2 = 118
both angle equal to 118

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.
