Answer:
L = 
L = 60.033
Step-by-step explanation:
<span>C = 45 + 18 + 27 - 21 - 93
C = -24
Let's use the variable C to represent the change in the balance in Cody's checking account. The easiest way to make the expression is to simply apply the additions and subtractions directly. So let's start with C
C
"Cody made deposits of $45, $18, and $27 into his checking account."
C = 45 + 18 + 27
"He then wrote checks for $21 and $93."
C = 45 + 18 + 27 - 21 - 93
So the expression to represent the change to Cody's checking account is
C = 45 + 18 + 27 - 21 - 93
Now to simplify it. All you need to do is combine terms together. How far you go is up to you. So let's do it.
C = 45 + 18 + 27 - 21 - 93
I'll add together all the deposits.
C = (45 + 18 + 27) - 21 - 93
C = 90 - 21 - 93
And I'll combine the checks.
C = 90 - 114
So now you can tell at a glance that Cody deposited $90 and wrote checks for $114. But we can make it simpler and combine those as well. So
C = -24
And this tells you that Cody's checking account balance is now $24 lower than it was before he started making deposits and writing checks.</span>
Yea I can help:)! What is it???
Answer:
infinitely many solutions
Step-by-step explanation:
x + 6y = -5
3x + 18y = -15
Multiply the first equation by 3
3(x + 6y) = -5*3
3x + 18y = -15
The two equations are identical. This means they have infinite solutions along the line x+6y = -5
Answer:
16
Step-by-step explanation:
Total cost = deposit + (hourly pay x number of hours)
let number of hours be h
68 = 20 + (3 × h)
3h = 68 - 20
3h = 48
h = 48/3
h = 16
Therefore the boat was rented for 16 hours
