Today, a bicycle rider rode her bike 5 1/2 miles to raise money for her school. Yesterday, she rode 6 1/4 miles her grandfather
Alex

Answer:

<em>.125 or 1/8</em>

Step-by-step explanation:

The question is looking for the difference divided by the long ride. The long ride is 6 1/4 miles, so now we need to find the difference.

In order to do this, we take the larger distance and subtract the smaller distance.

We would take (Tip: Use decimals when you can. They are easier to work with ) 6.25 - 5.5 and we get .75 or 3/4 of a mile.

Now, we put .75 over 6.25 and simplify.

.125 or 1/8

Maxim and Salma were asked to find an explicit formula for the sequence 54,63,72,81,... Maxim said the formula is f(n)=54+9n Sal
Sever21 [200]

ANSWER

The explicit rule is

f(n) = 45+9n

EXPLANATION

The given sequence is :

54,63,72,81,...

The first term of this sequence is

a = 54

The common difference is

d =63 - 54 = 9

The explicit rule is given by:

f(n) = a + d(n - 1)f(n) = 54+9(n -1 )

We expand to get:

f(n) = 54+9n -9

f(n) = 45+9n

None of them is correct .
