Cody made deposits of $45, $18, and $27 into his checking account. He then wrote checks for $21 and $93. Write an expression to show the change in Cody's account. Then simplify the expression. ((This is integers and rational numbers I really need help with this!))
Answer:
-24
Step-by-step explanation:
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.

If m<2 = 110°, and the m<6 = 110°, What can you conclude about line r and line s?
Be sure to include what theorem allows you to made your conclusion.
Lines r and s are parallel based on the given measure of angles 2 and 6.
Explanation:Based on the given information, if the measure of angle 2 is 110° and the measure of angle 6 is also 110°, then it can be concluded that lines r and s are parallel. This conclusion is based on the Alternate Interior Angles Theorem, which states that if a transversal intersects two parallel lines, then the alternate interior angles are congruent.

what rational number is equivalent to 6.121212121212?
Answer: 6.121212121212... = 202/33
Step-by-step explanation:
(612 - 6)/99 = 606/99 = 202/33 = 6.12121212121212... ∈ ℚ
In mathematics, a rational number is any number that can be expressed as the quotient or fraction of two integers, a numerator and a non-zero denominator.
Since 6.121212121212... is a number whose digits are periodic (12) , we can express it as a fraction 202/33, therefore is a rational number ∈ℚ.

Tom performed a total of 100 hours of community service. He served at three charities- Salvation Army, Red Cross and Rescue Missiom. The number of hours he served at the Red Cross was 19 hours more than at the Salvation Army. The number of hours he served at the Rescue Mission was 8 hours more than what he served at the Red Cross
Tom volunteered 18 hours at the Salvation Army, 37 hours at the Red Cross, and 45 hours at the Rescue Mission.
Let S represent the number of hours Tom served at the Salvation Army.
The number of hours at the Red Cross is 19 hours more than at the Salvation Army,Since the total number of hours Tom served is 100, we have,
S + R + M = 100
Substitute R and M with the expressions in terms of S:
S + (S + 19) + (S + 19 + 8) = 100
S + S + 19 + S + 27 = 100
3S + 46 = 100
3S = 54
S = 18
So, Tom served 18 hours at the Salvation Army. Now, we find the hours for the other two charities,
R = S + 19In summary, Tom volunteered 18 hours at the Salvation Army, 37 hours at the Red Cross, and 45 hours at the Rescue Mission.
Complete question-
