The number of boys . . . . . B
Twice the number of boys . . . 2B
4 more than twice the number of boys . . . 2B+4
You said that the number of girls is equal to that, so . . . G = 2B+4
But you also told us what G is: 16 = 2B+4
Subtract 4 from each side: 12 = 2B
Divide each side by 2 : 6 = B
There you have it. There are 6 boys in the club.

Answer:
(1) x(2/3) = y
(2) 27
(3) 8
(4) 9
Step-by-step explanation:
The first line of the table tells you how to fill in the second line. Use the x and y values from the third line to write (y/x) = (2/3). This gives you the equation ...
x(2/3) = y . . . . line (1)
For the remainder of the table, you can use the given value compared to the value in line 3 to see what the multiplier is for the other value.
(2): The multiplier is 18/2 = 9, so the missing x-value is 3×9 = 27.
(3): The multiplier is 12/3 = 4, so the missing y-value is 2×4 = 8.
(4): The multiplier is 6/2 = 3, so the missing x-value is 3×3 = 9.
The answer would be 10.4 since u wanted 10.44 rounded to nearest ''tenths'' that would be 1 decimal so basically move one decimal from the right to the left and u get 10.4.
X + y = 90 because the 2 angles add up to 90
Now m < x = five times m < y, so x = 5y or y = x/5
so the last choice is the correct one.
