Answer:

$y=-17$

Step-by-step explanation:

$3y+20=3+2y$

Start by subtracting 20 from each side...

$3y+20-20=3+2y-20\\3y=2y-17$

Now, subtract "2y" from each side...

$3y-2y=2y-2y-17\\y=-17$

Next, let's substitute -17 for y in the original equation to check our answer...

$3(-17)+20=3+2(-17)\\-51+20=3+(-34)\\-31=3-34\\-31=-31\rightarrow Correct!$

Therefore the answer is:

$y=-17$

3y + 20 = 3 + 2y

1y + 20 = 3

y = -17

Nazerhy deposits $8,000 in a certificate of deposit. the annual interest rate is 6%, and the interest will be compounded quarter

Bess [88]

The worth of the certificate in 10 years would be $14,512.15

Compound Interest and Its Formula

Compound interest is the type of interest based investment that causes initially modest sums of money to eventually increase to big sums. The formula for compound interest is given by,

$A = P(1+\frac{r}{n})^{nt}$

Here,

A is the final worth of the investment

P denotes the Principal amount of money that is invested

r denotes the rate of the compound interest

t denotes the time period in years

n denotes the number of times interest is compounded in one year

Given Information

P = $8,000

r = 6% = 0.06

n = 4 (∵ Compounded quarterly)

t = 10 years

Solving for A

Substituting the values of P, r, n, and t in the above mentioned formula of compound interest, we get,

$A = 8,000(1+\frac{0.06}{4})^{4*10}$

$A = 8,000(\frac{4.06}{4})^{40}$

$A = 8,000* 1.8140184$

$A = 14,512.14726$

Rounding the answer to two decimal places, we get,

$A = 14,512.15$

Therefore, Nazerhy would get $14,512.15 after 10 years.

Please solve this question faaaast

Kazeer [188]

Answer:

300-400

Step-by-step explanation:

The first step is finding the total of the data we have. So, we take 5 + 10 + 15 + 20 + 25 + 15 + 10 which equals 80.

The median is the middle point of all the data. If it's an odd number, you can calculate the median with the equation (n+1) / 2, plugging in the total amount of data for n.

When it's an even number though, there is no one middle point since the data splits evenly in 2, so we have to use 2 equations: n/2 & (n/2) + 1. Then, we find the average of those two data points. (Although, you don't have to do that for this particular question).

When we plug 80 in for n in both of these equations, we get 40 and 41.

To where this is in the question, we have to count up from the bottom of the chart. 1-5 is below 100, 6-15 is 100-200, 16-30 is 200-300, and 31-50 is 300-400.

Since 40 and 41 are between 31 and 50, the answer is 300-400.

Hope this helps! :)
