Answer:
If what I think youre saying is correct, then it should be 1/9
Step-by-step explanation:
4/15 + (-7/45)
Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.
12/45 + (-7/45)
As the fraction on the right side is negative, it is taken away from the left fraction, hence:
(12 - 7)/45
Therefore, with simple subtraction,
5/45
Simplify to 1/9
The average of the five consecutive numbers ending with b in discuss when expressed in terms of a is; Choice D; a+3.
<h3>What is the average of five consecutive integers ending with b?</h3>
First, since it was given in the task content that the average of six positive consecutive odd integers starting with a is equal to b, it therefore follows that;
(a+a+2+a+4+a+6+a+8+a+10)/6 = b
6b=6a+30
b=a+5
Also, let the average of the consecutive intergers ending with b be denoted by; x.
(b+b-1+b-2+b-3+b-4)/5 = x
=(5b-10)/5
=b–2
The average, x=b – 2 (where b = a-5)
Ultimately, the value of the required average is; = a+5-2 = a+3.
