C. 9
If 9 friends come then they all get 4 water balloons and 9 beads (36/9=4, 81/9=9)
The answer can't be D. 10 as 36/10 and 81/10 do not equal whole numbers and her friends can't have a fractional number of water balloons or beads
$1499 is the answer you multiply 100 by 15 then 100 by 29.99 and get 2999 and 1500. You subtract them together 2999-1500 to get 1499
Answer:
This equation is in standard form: ax 1+bx+c=0. Substitute 9 for a, 16 for b, and −112 for c in the quadratic formula 2a−b±b2−4ac.x= 2×9−16± 16^2−4×9(−112)Square 16.x=2×9−16±256−4×9(−112) Multiply −4 times 9.x=2×9−16± 256−36(−112) Multiply −36 times −112.x=2×9−16±256+4032 Add 256 to 4032.x=2×9−16±4288 Take the square root of 4288.x=2×9−16±8+67 Multiply 2 times 9x=18−16±8=67
