Answer:
His family ate 8 sugar cookies.
16 sugar cookies are left.
Step-by-step explanation:
- His family ate 1/3 <em>of </em>the 24 sugar cookies: 1/3 x 24= 8
- How many are left: 24-8=16
Step-by-step explanation:
98 = 188t - 16t^2
-16t^2 + 188t = 98
-16t^2 + 188t - 98 = 0
8t^2 - 94t + 49 = 0
Use the quadratic formula with a = 8 , b = -94 , c = 49 to get the solutions
t = [(47 - root 1817) / 8]≈ 0.55
and
t = [(47 + root 1817) / 8] ≈ 11.20
In order to solve for C, you need to get it by itself. You would do this by dividing both sides by A and B. if you do this you get C=D/AB. Therefore, your answer would be D
A: Deena subtracted 25, instead of adding it.
B: 9x - 25 = 88.
C: no idea
