If the average (arithmetic mean) of t and t+2 is x and the average of t and t-2 is y, what is the average of x and y?

t.

Step-by-step explanation:

(t + t + 2) / 2 = x

(2t + 2) / 2 = x

x = t + 1

(t + t - 2)/ 2 = y

y = t - 1

So the average of x and y

= (x + y) / 2 =   ( t + 1 + t - 1) / 2

= 2y / 2

= t.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
