What value of x makes this equation true?

Mathematics
1 answer:
Alex73 [517]3 years ago
4 0

Answer:

x=9/4=2.25

Step-by-step explanation:

The model is essentially saying:

3(-x)+10(1)=5(x)+8(-1)

Simplify:

-3x+10=5x-8

Subtract 5x from both sides:

-8x+10=-8

Subtract 10 from both sides:

-8x=-18

Divide both sides by -8. The negatives cancel:

x=18/8

Reduce:

x=9/4=2.25

And we're done!

Sung Lee invests $5,000 at age 18. He hopes the investment will be worth $20,000 when he turns 25. If the interest compounds con
Temka [501]

Answer:

19.8%

Step-by-step explanation:

We have the following formula for continuous compound interest:

A = P * e ^ (i * t)

Where:

A is the final value

P is the initial investment

i is the interest rate in decimal

t is time.

The time can be calculated as follows:

25 - 18 = 7

That is, the time corresponds to 7 years. In addition, A is 20,000 for A and P would be 5,000, we replace:

20000 = 5000 * e ^ (7 * i)

20000/5000 = e ^ (7 * i)

e ^ (7 * i) = 4

ln e ^ (7 * i) = ln 4

7 * i = ln 4

i = (ln 4) / 7

i = 0.198

Which means that the rounded percentage will be 19.8% per year
