When x=12,y=8. Find x when y=12

1 answer:

3 0

To do this you multiply 12 by 12 to get 144. Now you want to divide 144 by 8. This gives you 18. Therefore, when y is equal to 12, x would be equal to 64.

Melanie saves $20 every month in her savings account. She

OLga [1]

Let x represent the amount of months she has been saving for.

20x - 60 = 280

Solve for x.

20x - 60 = 280

~Add 60 to both sides

20x - 60 + 60 = 280 + 60

~Simplify

20x = 340

~Divide 20 to both sides

20x/20 = 340/20

~Simplify

x = 17

Therefore, Melanie has saved for 17 months.

Best of Luck!

Use the digits 5,4 and 8 once each to write an odd number greater than seven hundred

natali 33 [55]

845 because 800 is greater than 700 and 845 is an odd number because it ends in 5 (which is an odd number).

An investment of $900 earns 6% annual interest and is compounded semi-annually. Write an equation

nalin [4]

Answer:

$A=900(1+\frac{0.06}{2})^{2(t)}$

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

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

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 6% into a decimal:

6% -> $\frac{6}{100}$ -> 0.06

Since the interest is compounded semi-annually, we will use 2 for n. Lets plug in the values now and your equation will be:

$A=900(1+\frac{0.06}{2})^{2(t)}$
