Answer:
10 boys, 15 girls
Step-by-step explanation:
Original ratio: 2 boys/3 girls
let x be the scale factor of the ratio
2x plus 5 boys over 3x girls = 1 (because the # of boys/girls are the same)-------> 2x+5/3x = 1
Simplify: 2x+5=3x
Simplify: 5=x
plug x back into the original ratio: 10/15
Check: 10/15 = 2/3
10 boys + 5 boys = 15, 15/15 = 1
Answer: b = 5
Step-by-step explanation:
Here parallelogram wxyz has diagonals,
4b-6 and 2b+4
Since, If a parallelogram has a equal pair of congruent or equal diagonal it is called a rectangle.
Thus, if wxyz is a rectangle,
Then, 4 b - 6 = 2 b + 4
⇒ 4b = 2 b + 4 + 6
⇒ 4 b = 2 b + 10
⇒ 4 b - 2 b = 10
⇒ 2 b = 10
⇒ b = 5
Hence, for b = 5, wxyz is a rectangle.
