Answer:
25
Step-by-step explanation:
Do 5 X times 15 = 75 x
Do 75x / 3 = 25
Answer: the smaller number is 11, and the larger number is 28
Step-by-step explanation:
Let x = the smaller number; then the greater number is 3x-5. When you add these they must equal 39, so:
x + (3x-5) = 39
4x - 5 = 39; now add 5 to both sides:
4x = 44; now divide both sides by 4, and you get x =11, which is the smaller number. The larger number would be 3(11)-5 = 33 - 5 = 28
By the inclusion/exclusion principle,
n(J ∩ K) = n(J) + n(K) - n(J U K)
n(J ∩ K) = 285 + 197 - 431
n(J ∩ K) = 51
you divide 8 by both sides. which will give you 14
so z= 14
Answer:
I cannot say much without a lot of background, but I know that p makes 90 degrees when it intersects m and n, and that they do not necessarily have the same length, because it does not specify.
