Answer:
The cost of one unit of electricity is $0.185
Step-by-step explanation:
Amount charged = $120.99
Units of electricity used = 654
The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.
So that,
cost of one unit of electricity = 
= 0.185
cost of one unit of electricity = $0.185
This implies that the cost of electricity used is charged at $0.185 per unit.
Thus for 654 units of electricity used, the cost would be;
654 x $0.185 = $120.99
Answer:
y=-2
Step-by-step explanation:
y+3y+5y=−18
Combine like terms
9y = -18
Divide each side by 9
9y/9 = -18/9
y = -2

Answer:
Step-by-step explanation:
The given sequence is 2, 4, 6, ....
We need to write an explicit formula for 
. The firts term is 2, second term is 4 and third term is 6 and so on.
Each term is 2 greater than the term before it. Thus we can write it as follows :
Where
n = 1,2,3....
Hence, the explicit formula is .
