suppose a refrigerator sells for $700 per and costs $85 a year for electricity. write the expression for the cost to buy and run
the refrigerator for x years?
2 answers:
Cost of refrigerator = $700
Cost of electricity per year = $85
So cost of electricity for x years = $85x
Run the refrigerator for x years
Total cost to buy and run the refrigerator for x years = cost of refrigerator + cost of electricity for x years
Total cost to buy and run the refrigerator for x years = 700 + 85x
X=700R+85Y
R= Number of Refrigerators
Y= Number of Years

Answer:
X= 3.7
Step-by-step explanation:
Perimeter of rectangle= 2(L+B)
37= 2(4X+X)
37= 2(5X)
37= 10X
37/10=X
3.7= X
The answer would be 5 + 15i/2.
1. 5 + 3i/2 + 6i
2. 5 + (3/2i + 6i)
3. 5 + 15i/2.
Using cosine law,
d^2 = 65^2 + 35^2 - 2(65)(35)cos140
= 8935.5022
d = sqrt(8935.5022)
= 94.5 m
Angle = inverseCos(35sin40 / 94.5) = 76.23 degrees South of East
