The space is the arrangement of all conceivable x-values which will influence the capacity "to work", and will yield genuine y-values. When finding the space, recall: The denominator (base) of a part can't be zero. The number under a square root sign must be certain in this segment.
Hope you understand!!!!!!
For this problem, let x be the number of children and y for adults. Formulate the equations: 1st equation, x + y = 3,200 and 2nd equation 5x + 9y = 24,000. Re-arrange 1st equation into x = 3200 - y. Then, substitute into 2nd equation, 5(3,200-y) + 9y = 24,000. Then, solve for y. The 16,000 - 5y + 9y = 24000. Final answer is, y = 2000 adults went to watch the movie.
Since all of a squares sides are the same length, we can use 3.2 cm in the following equations:
P= 2L + 2W and A= L x W
P= 2(3.2) + 2(3.2) which is the same as P= 4(3.2)
P= 12.8 cm
A= 3.2 x 3.2
A= 10.24 cm^2
