There are 4 boys and 7 girls with a total of 11. Now, how many 4 persons group combinations are possible.
=> 1 boy and 3 girls
=> 2 boys and 2 girls
=> 3 boys and 1 girl
Thus, there are 3 possible combinations that might happen.
-20a divided by 12b would be -1.6
Answer:
y=4/5+3 and 3/5
Step-by-step explanation:
18a:16 18b:32 % means out of 100
4(x + 9) + 5x = 9x - 36
=> 4x + 36 + 5x = 9x - 36
=> 9x + 36 = 9x - 36
=> 9x - 9x = -36 - 36
=> 0 = -72
You can see that the equation doesn't hold true.
So there is no solution for this equation.
Answer is C. no real solutions
