What is the solution to 1/3x-5+171=x

Answers

(1/3)x-5+171=x
I move the x on the right to the left so
(1/3)x-x-5+171=0
I then simplify so
(-2/3)x+166=0
I subtract 166 from both sides so
(-2/3)x = -166
Then I divide (-2/3) from both sides so
x = -166/(-2/3)
x = 249
and that's the answer
hope this helps

x in (-oo:+oo)

(1/3)*x-5+171 = x // - x

(1/3)*x-x-5+171 = 0

166-2/3*x = 0 // - 166

-2/3*x = -166 // : -2/3

x = -166/(-2/3)

x = 249

x = 249

What is the square root of 65

Answers

one way is factor
exg
if you wanted to find the square root of 36 you would factor
36=2 times 2 times 3 times 3
then group repeeting numbers then write only one of them
36=(2 times 2) times (3 times 3)
squareroot36=2 times 3=6

so factor 65
65=5 times 13
that doesn't help
next step
find squares close to that numbers

2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49

the answer is a little more than 8

How many 2/5 are in 1

Answers

Steps:
1. If you do 2/5 + 2/5= 4/5. 4/5 would be the closest you could get to 1
2. So, you only have 1/5 left
3. That means that 2/5 can only go into 1 two times
4. Your answer is that there are two 2/5 in 1

You want to have $3000 in your savings account after 3 years. Find the amount you should deposit for each of the situations described below.a. the account pays 3% annual interest compounded quarterly
b. the account pays 2.25% annual interest compounded monthly
c. the account pays 2% annual interest compounded daily
(SHOW YOUR WORK)

Answers

A) take the annual interest and divide it by 4 since it is compounded quarterly.
.03 ÷ 4 = .0075. Add 1 to include your principal. 1.0075 and raise it to the 12th power since you will be doing this 4 times a year for 3 years (4 x 3 =12).
Since you want 3000 at the end of this period you should do:

3000 ÷ (1.0075¹²) and you get $2742.71 which is how much you should put in.

B) .001875 is the monthly rate of 2.25% (.0225 divided by 12)
This time we have to do it to the 36th power since there are 36 months in 3 years.
Don't forget to add the 1 to include your money.
3000 ÷ (1.001875¹²) = $2804.36

C) 2% compounded daily means .02 ÷ 365 = (about) .00005479
Once again we add our principal by putting a 1 in front 1.00005479
3000 ÷ (1.00005479¹⁰⁹⁵) (1095 because 365 x 3 years = 1095 days)
= $2825.31

Just to emphasize why I always added 1. Since I am dividing, dividing by 1 givesyou the same as you start with (3000 ÷1 is still 3000) The small numbers after the 1 reduce the amount (3000) to the amount you will have to put in to realize $3000 at the end of each time period.

Final answer:

To have $3000 in the savings account after 3 years, you should deposit $2688.97 for situation a, $2669.29 for situation b, and $2667.99 for situation c.

Explanation:

To find the amount you should deposit for each situation, we can use the formula for compound interest:

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

where A is the final amount, P is the principal amount (the initial deposit), r is the annual interest rate (in decimal form), n is the number of times interest is compounded per year, and t is the number of years.

Using the given information, we can calculate:

For situation a (3% annual interest compounded quarterly), we have A = $3000, r = 3% = 0.03, n = 4 (since interest is compounded quarterly), and t = 3. Rearranging the formula, we get:
P = A / (1 + (r/n))^(nt) = $3000 / (1 + (0.03/4))^(4*3) = $2688.97 (rounded to two decimal places).
For situation b (2.25% annual interest compounded monthly), we have A = $3000, r = 2.25% = 0.0225, n = 12 (since interest is compounded monthly), and t = 3. Substituting these values into the formula, we get:
P = A / (1 + (r/n))^(nt) = $3000 / (1 + (0.0225/12))^(12*3) = $2669.29 (rounded to two decimal places).
For situation c (2% annual interest compounded daily), we have A = $3000, r = 2% = 0.02, n = 365 (since interest is compounded daily), and t = 3. Plugging these values into the formula, we get:
P = A / (1 + (r/n))^(nt) = $3000 / (1 + (0.02/365))^(365*3) = $2667.99 (rounded to two decimal places).
