The equation is not setup properly, possibly it is your teacher's fault.
From external research, I would say the answer is x = -12.
Answer:
he got 20% wrong
he got a B
Step-by-step explanation:
The number of balloons needed to fill the classroom are 46240 balloons (approx)
Concept: Fermi process is the technique that helps to formulate an answer to a problem based on a series of logical assumptions.
No. of balloons = Volume of rectangular prism/ Volume of each sphere (balloon)
Given: The classroom is a rectangular prism with a length of 38 ft, a width of 52 ft, and a height of 12 ft, and the balloons are spheres with a radius of 0.35 ft.
No. of balloons = Volume of rectangular prism/ Volume of each sphere (balloon)
No. of Balloons = 38*52*12/3.14*0.35*0.35*(4/3)
No. of Balloons = 23712/0.5128 = 46240 balloons (approx)

Answer:
67.5
Step-by-step explanation:
this gives you the basis of the problem, 2 pages every 3 minutes, so that means that you have to divide 45 by 2, this will give you 22.5
then you multiply by 3 because 22.5 is how many sets of 2 Ella has to read, and if we remember every set of 2 pages takes 3 minutes, so 22.5 times 3 is 67.5, but if you want the answer in time it would be 67 minutes and 30 seconds because a minute is 60 seconds and half of that is 30
