Answer:
350 students
Step-by-step explanation:
Let:
a = number of adults attending
s = number of students attending
a + s = 950 (1) (given)
9a + 6.5s = 7675 (2) (cost per adult * number of adults + cost per student * number of students = total amount spent)
Looking for s. Multiply (1) by 9 then subtract eq (2), this will eliminate the variable a:
(1) 9a + 9s = 8550
- (2) 9a + 6.5s = 7675
-------------------------------
0a + 2.5s = 875
s = 875/2.5 = 350 students
Its c.
If you will substitute those numbers to the pair of equations, both will be true.

Answer:
∠ X = 30°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinX = = = = = , then
∠ X = ( ) = 30°
Answer: Slope intercept form is y=mx+b, where m is slope and b is the y-intercept. We can use this form of a linear equation to draw the graph of that equation on the x-y coordinate plane.
