Let x equal the number of adult tickets sold.
X + 3X=512
(I put 3x because we know the students sold 3 times as many).
Solve for X.
X+3X=512
4X=512
4X/4=512/4
X=128

Answer:
Let's solve your equation step-by-step.
3 / 4 y = 9
Step 1: Multiply both sides by 4/3.
(4 / 3 ) * ( 3 / 4 y ) = ( 4 / 3 ) * ( 9 )
y = 12
Answer:
y = 12

Insert 12 to the y value:
3 / 4 ( 12 ) = 9
9 = 9

Answer:
0.51 cm
Step-by-step explanation:
In right triangle MNP, MP = 4 cm, m∠N = 90°, m∠P = 21°
By the sine definition,
Now, consider right triangle HMN (it is right because NH is an altitude). By the cosine definition,
In the right triangle, two acute angles are always complementary, so
Thus,
