Answer:
14. x=30, y=15, z=165
15. x=10, y=25
Step-by-step explanation:
Answer:A
Step-by-step explanation:
X=2(y+1)^2-6
Add the amount of students together (21+24=45)
Divide by three to see how many will be in each group. (45/3 = 15)
15 in each group!
Answer:
48/73
Step-by-step explanation:
cos S in ratio = ?
cos S = Adjacent/hypothenus
adjacent is the dimension of line aside the opposite (the line facing angle S, the hypotenus(longest line)
adjacent = 48
hypothenus = 73
cos S= 48/73
2 x (3+6z) = 6 +12z
This is how you do it
