You deposit $2000 into a savings account to pay 5% interest compounded annually if you make no more deposit or any withdrawal is
Bond [772]

Answer: A = 2000(1.05)^5

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $2000

r = 5% = 5/100 = 0.05

n = 1 because it was compounded once in a year.

t = 5 years

Therefore, the equation that shows how much money will be in the account after five years is

A = 2000(1 + 0.05/1)^1 × 5

A = 2000(1.05)^5

Simplify.<br> (-3.9) + (6.01) - (-7.423)<br> -5.513.<br> 2.487.<br> 9.533.
lianna [129]
First, since we must follow PEMDAS, we need to do the operation that is first, which is addition. 

-3.9 + 6.01  ← Adding a negative means subtracting, then giving the sign of the bigger number.

So now we solved those and we got this answer: 2.11

Now, we need to subtract and re-write the expression.

2.11 - (-7.423) = 2.11 + 7.423= 9.533

Ok....so now we have our final answer, and we have the choices above.

The only answer that matches ours is the last one.

Final answer: 9.533

Hope I helped ^_^

A - 2 + 3 = -2 pls answer
Kobotan [32]

Answer:

-3

Step-by-step explanation:

Bring -2 to the other side and A to the other side

<em>-</em><em>2</em><em> </em><em>Become </em><em>2</em><em> </em><em>because </em><em>of </em><em>flipping</em>

<em>And </em><em>A </em><em>becomes </em><em>-A </em><em>because </em><em>of </em><em>flipping</em>

<em>2</em><em>-</em><em>2</em><em>+</em><em>3</em><em>=</em><em>-A</em>

<em>Flip </em><em>the </em><em>whole </em><em>equation </em><em>to </em><em>avoid </em><em>confusion</em>

<em>-A=</em><em>2</em><em>-</em><em>2</em><em>+</em><em>3</em>

<em>-</em><em>A=</em><em>+</em><em>3</em>

Bring the minus sign to the other side,

<u>A=-3</u>

<u>-</u><u>3</u><u> </u><u>-</u><u>2</u><u> </u><u>+</u><u>3</u><u> </u><u>=</u><u> </u><u>-</u><u> </u><u>2</u>

<u>Which </u><u>make </u><u>the </u><u>statement</u><u> </u><u>correct.</u>

<u>I hope </u><u>this </u><u>explanation</u><u> </u><u>helps, dont hesitate to ask for any question.Mark me as brainliest is appreciated.Tq!!</u>
