Answer:
x = 16
Step-by-step explanation:
The angle bisector divides the sides proportionally.
(x -4)/9 = x/12
4(x -4) = 3x . . . . . . . multiply by 36
x = 16 . . . . . . . . . . . . add 16-3x to both sides, simplify
I think the answer is c because it is a even number and the answer can also be a but i think it is c
Answer:
348 out of 725
Step-by-step explanation:
This is a ratio question, giving us a sample that we can use to extend the number to all students.
12/25 students play a sport so we want the value of x in x/725
So:
12/25 = x/725
Cross-Multiply:
25x = 8700
Divide by 25 to get x:
348
You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).
