Answer:

21/8

Step-by-step explanation:

Simplify the following:

6 + 1/4 - (3 + 5/8)

Put 3 + 5/8 over the common denominator 8. 3 + 5/8 = (8×3)/8 + 5/8:

6 + 1/4 - (8×3)/8 + 5/8

8×3 = 24:

6 + 1/4 - (24/8 + 5/8)

24/8 + 5/8 = (24 + 5)/8:

6 + 1/4 - (24 + 5)/8

24 + 5 = 29:

6 + 1/4 - 29/8

Put 6 + 1/4 - 29/8 over the common denominator 8. 6 + 1/4 - 29/8 = (8×6)/8 + 2/8 - 29/8:

(8×6)/8 + 2/8 - 29/8

8×6 = 48:

48/8 + 2/8 - 29/8

48/8 + 2/8 - 29/8 = (48 + 2 - 29)/8:

(48 + 2 - 29)/8

The 5 positive integers a, a, a, b, and c have an average of a. What is the value of (b+c)/2?

makkiz [27]

We are given that a+a+a+b+c=5a=a+a+a+a+a
subtract a+a+a from both sides, then
b+c=a+a
divide by two,
(b+c)/2=(a+a)/2=a
