1.) -4
2.) Parenthesis, so probably 1+1
I could be wrong. Sorry XD
50 = 25 * 2 = 5 * 5 * 2
44 = 22 * 2 = 11 * 2 * 2
Answer:
25 males and 8 females.
Step-by-step explanation:
If x is the number of males and y = number of females we have the system:
x + y = 33
x - y = 17 Adding:
2x = 50
x = 25
so y = 33 - 25 = 8.
For number 9 just take the two functions and multiply or add them I can’t tell what sign that is
x = 35
The angles are vertically opposite and equal thus
4x + 20 = 3x + 55
subtract 3x from both sides
4x - 3x + 20 = 55
x + 20 = 55
subtract 20 from both sides
x = 55 - 20 = 35
