Answer:
A
Step-by-step explanation:
If you plug in 0 for w, the number of weeks, you'll see that s = 80. Meaning, at week 0 he ha 80
Answer:
As
parts per million can be calculated by applying formula Ppm=(mass of solute/mass of solution)×1,000,000
In given condition
Mass of solute which is NaCl is 284g
Mass of solution which is watervis 100g
Ppm=284/100×1,000,000
=284000ppm

The process is also known as recurssion which is most often the term used in computer science.
Both terms mean that you do something to the previous term to get to the next term. In general terms it is written like this
fn = f_(n - 1) + d for an arithmetic progression. The series begins with n =2 , 3 , 4 , 5 , 6 ...
f1 is defined as 7
so f2 = f_(2 - 1) - 2 or
f2 = f_1 - 2
f2 = 7 - 2
f2 = 5
f3 = f_(3 - 1) - 2 or
f3 = f_2 - 2
f3 = 5 - 2
f3 = 3 and so on. Computers handle this much better than people do. They can go through a thousand such calculations most of the time in less than a second.

Answer:
x = 5
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Isolate the variable, x. Subtract x and 2 from both sides:
-2x (-x) + 2 (-2) = x (-x) - 13 (-2)
-2x - x = -13 - 2
Simplify. Combine like terms:
-2x - x = -13 - 2
-3x = -15
Divide -3 from both sides:
(-3x)/-3 = (-15)/-3
x = -15/-3
x = 5
x = 5 is your answer.
