Answer:

$\bold{161}$

Step-by-step explanation:

We know that $n$ here is represented by 55 (nth term = 55th term), so we get the 55th term is

-1 + 3(55 - 1)

= -1 + 3(54)

= -1 + 162

= 161

Which is our answer.

This formula means that a(n) for n, when n is the term number, will give you the term. Meaning, we just have to plug in 55 for n.

a(55) = -1 + 3(55 - 1)

a(55) = -1 + 3 * 54

a(55) = -1 + 162

a(55) = 161

Kyla spends 60 Minutes of each day exercising. Let d be the number of days that Kyla exercises, and let m represent the total nu

stealth61 [152]

Answer: There is linear relationship between the number of days that Kyla exercise in the total minutes that she exercises.

The independent variable is 'd' and m is the dependent variable which depends on the number of days she exercise.

The linear equation for the situation is given by

$m=60d$

Step-by-step explanation:

Let d be the number of days that Kyla exercises, and let m represent the total numbers of minutes she exercise.

Kyla spends 60 Minutes of each day exercising which is constant .

Then the total numbers of minutes she exercise(m) in d days is given by

$m=60d$ which is the linear equation.

The relationship between the number of days that Kyla exercise in the total minutes that she exercises is linear, where d is the independent variable, and m is the dependent variable which depends on the number of days she exercise.

[ad d increases m increases by rate of 60 minutes per day]

The linear equation for the situation is given by

$m=60d$
