<em>(C). {3} </em>
Step-by-step explanation:
= 
+ 
( x ≠ - 1 )
- + = 0
- 
= 0
= 0 ⇒ <em>x = 3</em>
Answer:
C = 6.75n + 50
Step-by-step explanation:
The equation for the cost of renting the party room can be written in the form;
C= mn+k ......i
Where C = cost
n = number of people
Substituting the 2 cases into the equation we have,
Case 1
117.5 = 10m + k ......1
Case 2
151.25 = 15m + k .....2
Subtracting eqn 1 from 2 we have
151.25 - 117.50 = 15m - 10m
5m = 33.75
m = 33.75/5 = 6.75
Substituting m = 6.75 into eqn 1, we have
117.50 = 10(6.75) + k
k = 117.5 - 67.50
k = 50
Therefore, rewriting the eqn i, we have
C = 6.75n + 50
False because you walk both the sides so you would have to do 360x2 added to 160x2
3 possible solutions.
The reason is because of the degree, which is 3
