Assume that,
adult = x
child = y
x+2y = 35 (1st equation)
2x+3y = 60 (2nd equation)
x = 35-2y (3rd equation)
Substitute 3 into 2 :
2(35-2y) + 3y =60
70-4y +3y = 60
y = 10
x+2y = 35
x+2(10) =35
x +20 =35
x = 15
One adult = $15
A. 176 because if there are 252 total and 76 on the balcony your answer is 252-76.
Point slope form will give you the point
y - y1 = m(x- x1)
when the equation says -, the number is positive. when the equation says +, the number is negative
in this case the point is (-6,5)
Answer:
see explanation
Step-by-step explanation:
the error in the question is that
sec²x = 
≠ 
, and
csc²x = ≠
have been used incorrectly in simplifying the expression
then
= 
= 
= × 
= 
= tan²x
