Answer:

  • second
  • 3
  • first
  • is

Step-by-step explanation:

We observe that the second equation of System B has had the x-term eliminated. That can be accomplished by adding 3 times the first equation to the second.

"To get System B, the <u> second </u> equation in System A was replaced by the sum of that equation and <u> 3 </u> times the <u> first </u> equation. The solution <u> is </u> the same as the solution to System A."

John types 62 words per minute. Which an expression for the number of words he types in m minutes?
andrezito [222]

Answer:

w = 62m

Step-by-step explanation:

We need to make an expression for the numbers of words (w) John types in m minutes.

We know he types 62 words in 1 minute, so 62 is the coefficient of m.

The dependent variable here is w, so that should on the left of the equal sign.

m, on the other hand, is independent, so that's on the right of the equal sign.

So, the expression is w = 62m.

Jennifer places $500 into a savings account that is paying 1.5% annual interest. The interest is compounded monthly. How much mo
Anna11 [10]

Answer:

$522.99

Step-by-step explanation:

FV  = P (1 + \frac{r}{n} )^n^t

Fv = total amount plus interest over the given period of time

P = Principal amount deposited i.e $500

r = interest given 1.5% i.e 0.015

n = period of time the principal remains deposited. In this case annually i.e 12 months

FV = 500 ( 1 + \frac{0.015}{12} ) ^1^2^X^3

FV = 500 ( 1.04599)

FV = $522.99

What should you do first in order to reconcile your checkbook register?
Anarel [89]
First, you need to have your bank statement and your check register.

Then, compare all your deposits from your checkbook register to your bank statement credits to determine the amount of deposit not yet credited by the bank, which is called your Deposit in Transit.

Next, compare all your disbursements from your checkbook register to all the debits in your bank statement to determine the amount of disbursements not yet debited by the bank.

Also, you need to check for any bank charges already debited to your bank account but not yet recorded.

  • Diameter: d = 2r
  • Area of a Circle: A = πr²

Step-by-step explanation:

<u>Step 1: Define</u>

d = 30 m

<u>Step 2: Find Area</u>

  1. Substitute [D]:                    30 m = 2r
  2. Isolate <em>r</em>:                             15 m = r
  3. Rewrite:                              r = 15 m
  4. Substitute [AC]:                 A = π(15 m)²
  5. Rearrange:                        A = 15²π
