Answer:
The hourly fee for rototiller is $3 per hour.
Step-by-step explanation:
We are given the following in the equation:
The rental company charged an initial fee of $43 with an additional fee per hour.
Let h represents the hourly fee.
The family paid $64 after renting the rototiller for 7 hours.
Thus, we can write the equation:
Solving the equation, we get,
Thus, the hourly fee is $3 per hour.
Equation:
where C(x) is the cost function and x is the number of hours rototiller is rented.
The hourly fee for rototiller is $3 per hour.

<h3>What is an Arithmetic Progression?</h3>
A sequence of numbers that has a fixed common difference between any two consecutive numbers is called an arithmetic progression (A.P.)
Given,
Amount in Janae's account = $ 50
Amount she wishes to save for 10 days = $ 5
This scenario models an arithmetic progression(A.P)
In an A.P,
a _n = a + (n-1)d
where a _n = nth term, a is the first term, n is the no. of terms and d is the common difference.
In this question, a = 50, n = 10, d = 5 and we have to find out a _n
Therefore, a _n = 50 + (10-1)x5
= 50 + 45 = 95
Answer:- Janae will have $ 95 in her account after 10 days.

Answer:
A) 3a = 180°
B) a+ 55° + 36° = 180°
C) x + y + z = 180°
Step-by-step explanation:
The answer is the A option since all the side of the triangle could be the same, making it an equilateral triangle. ( 60° + 60° + 60° = 180° )
The sum means that all the angles are added, not necessarily being similar terms, which equals to 180°.
The terms don't have to be similar, for instance the B option,
a+ 55° + 36° = 180°
since you could find the value of a.
The same thing goes for C.
(Extra)
It is not D since x is multiplied with 3, not giving the sum.
It is not E since all the 3 terms are multiplied, not giving the sum.
