Answer:
It costs $42.43
Step-by-step explanation:
Lets explain how to solve the problem
- The cost of 
kilogram of candy is $7.5
- We need to find the cost of 
kilogram
We can use the ratio to find the answer
======= Dollar : Kilogram
======= 7.5 :
======= c :
By using cross multiplication
∴ c × = 7.5 ×
∵ = 
∴ = 
∴ c × = 7.5 ×
∴ c × = 
Divide both sides by
∴ c = ÷
Change the division sign to multiplication sign and reciprocal the
fraction after the division sign
∴ c = × 
∴ c = 
= 42.43 dollars
∵ c represents the cost of kg
∴ It costs $42.43
Answer:
cant be factored
Step-by-step explanation:
Using the linear regression equation, the concentration of the unknown solution is 0.2161 M.
Linear regression describes the relationship of two variables. It may not be exact but it is the line that best fit the data. The equation for a linear regression is in the form y = bx + a, where x and y are the two variables.
If the absorbance of an unknown was determined to be 0.67 absorbance units, using the linear regression equation provided from the plot, substitute the value of absorbance to the variable y and solve for the value of x or the concentration.
y = 3.8674x - 0.1657
0.67 = 3.8674x - 0.1657
3.8674x = 0.67 + 0.1657
3.8674x = 0.8357
x = 0.2161
Hence, the concentration is 0.2161 M.

Make bottom numbers same
convert to improper fraction
1 and 5/6=1+5/6=6/6+5/6=11/6
1/2 and 11/6
2 times 3=6
1/2 times 3/3=3/6
1/2+11/6=3/6+11/6=(4+11)/6=14/6
answer is A
This is a function when u have f(n) u plug in the number for example 1 because the number -13 is the first number in the sequence
