Answer:
Step-by-step explanation:
Given: Equation is 
To find: flaw in Gwendolyn's work and the correct solution to the equation.
Solution:
In the given question,
the first step is
The second step is 
(This step is obtained on multiplying 
by 
)
The third step is 
This step is wrong as on transposing 12 from left side of the equation in the second step to the right side, the following equation is obtained:
So, the correct solution is
The answer is
A(m) = 12 + 2m
B(m) = 10 + 3m
m - the number of months
F(m) - growth in a function of months m
Species A is 12 cm tall, so the number 12 is independent on a number of months. But it <span>grows 2 cm per month. This means that in m months it will grow 2 * m. So, its function is: A(m) = 12 + 2m
Similarly, s</span>pecies B is 10 cm tall, so the number 10 is independent on a number of months. But it grows 3 cm per month. This means that in m months it will grow 3 * m. So, its function is: B(m) = 10 + 3m
Answer:
$39
Step-by-step explanation:
He has $115 total, and he spent it on shirts and pants
First, find how much money he spent
Shirts:
5 shirts at $11 each
5*11=55
$55
Pants:
$21
To find how much he has left, subtract what he spent from the total amount of money he had to begin with
total-shirts-pants
115-55-21=39
He has $39 left to buy more clothes
Reduce the expression by canceling the common factors. Solution: 3/20 Decimal form: 0.15
