The cost of one chapstick is $1 and one eyeliner is $2.
Step-by-step explanation:
Let,
Cost of one chapstick = x
Cost of one eyeliner = y
According to given statement;
3x+2y=7 Eqn 1
4x+5y=14 Eqn 2
Multiplying Eqn 1 by 4
Multiplying Eqn 2 by 3
Subtracting Eqn 3 from Eqn 4
Dividing both sides by 7
Putting y=2 in Eqn 1
Dividing both sides by 3
The cost of one chapstick is $1 and one eyeliner is $2.

X = 2y/5 - 9/5
y = 5x/2 + 9/2
(I don't know if this is correct)

I'm assuming you meant 62p=610. If this is the case, then p = 610/62, or 9.84.
This does not match any of the four answer choices.

Answer:
? = 16
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan ? = opp side / adj
tan ? = 13 / 46
Taking the inverse tan of each side
tan ^ -1 ( tan ? ) = tan ^-1 ( 13/46)
? = 15.78075
To the nearest degree
? = 16
