Answer:65miles
Step-by-step explanation:
Let the needed miles be x
(67+62+59+47+x)/5=60
235+x=60×5
235+x=300
x=300-235
x=65miles
250 × 3 = 750
Your answer is D. <span>750 mi</span>
The pattern would be 5,7,12,20,31,45
Answer:
x= -2
Step-by-step explanation:
You use explicit funtion to find a particular number in the list without needing to write all the list down.
For example, the first range of number has a constant difference of 5. Its explicit funtion would be: x(n)=3+(n-1)*5 (with x is the number you need to find, n is the number's position in the range)
Basically, a explicit funtion in that problem has the form:
x(n)=f+(n-1)*d
with:
x= the number needed to find
n= the number's position
f = the first number in the range
d = the distance
Good luck!
