Answer:
first number=15 second number=6
Step-by-step explanation:
lets take the first and second numbers as "a" and "b"
a-b=9
a+2b=27 (solve these equations simultaneously)
eliminating a
-3b= -18
b= 6
then substitute in the first equation
a-6=9
a=9+6
a=15
I really hope you know how to solve equations simultaneously
hope this helped
<h3>Straightforward Solution</h3>
The long way around is to compute the return from each investment and relate the sum of those returns to the toal investment.
You have invested $33×100 = $3300 in clooney. You expect a return of 20%×$3300 = $660 on that investment.
You have invested $42×100 = $4200 in marx. You expect a return of 12%×$4200 = $504 on that investment.
Your total expected return is $660 + 504 = $1164. Your total investment is $3300 + 4200 = $7500. Thus, the return on your investment is expected to be
... $1164/$7500 = 0.1552 ≈ 15.5% . . . . matches choice a.
<h3>Alternative Solution</h3>
Since the same number of shares is involved in both investments, you can weight the expected return percentages by the ratio of share price to total of share prices:
expected return = (33/75)×20% + (42/75)×12%
... = 8.80% + 6.72% = 15.52%
Answer:
x = -18
Step-by-step explanation:
Hello!!!
So we are given some number, which we will call x for simplicity purposes. They tell us that number is divided by 4 so x/4, and then 17 is added, so we now have x/4+17 and they tell us this combination is equal to 25 so set what we have so far equal to 25. So we have finally x/4+17=25. Now we just solve for x!
x/4+17=25 first we subtract 17 from both sides leaving us with, x/4=8 so now See need to multiply by 4 on both sides to clear the fraction and get x alone. So we have now
x=8*4 so x=32
Now we can check our answer by putting our value of x into equation and make sure it’s true. So we have for our check,
32/4+17=25 and 32/4 is 8 so we have 8+17=25 which is 25=25 so our equation is true and our answer is correct!!
Hope this helps you understand the concept!! Any questions please just ask!! Thank you so much!!
