Ax + z = aw - y....subtract aw from both sides
ax - aw + z = -y....subtract z from both sides
ax - aw = -y - z....factor out a on the left side
a(x - w) = -y - z...divide both sides by (x-w)
a = (-y - z) / (x - w)
Answer:
250 Students are musicians, 200 are not.
Step-by-step explanation:
Decimal Version:
If we take "5 out of every nine students are musicians" and make this a fraction we get 5/9. 5/9 as a decimal is approximately 55.555555555556. 55.555555555556% of 450 = 250. So that means 250 students are musicians.
Fraction Version : See attached image.
Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°)
Answer:
0%
Step-by-step explanation:
10% + -10% = 0%, so the percent gain and loss is 0% (because both tables cost the same).
You could do 21-5 and get the answer 16
A= 16+5 = 21
So therefor, he is 16 years old now.
