Answer: I'm pretty sure the correct answer is (B) Let me know if i'm correct!
Step-by-step explanation:
16(4) = 64. 7(3) = 21
64/21 simplifies to 3 and 1/21 as 21 goes into 64 three times. Option C is your answer.
4x+3y=19 and 6x-5y=-57
eliminate
multiply first equation by -6 and 2nd by 4
and add them
-24x-18y=-114
<u>24x-20y=-228 +</u>
0x-38y=-342
-38y=-342
divide both sides by -38
y=9
sub back
4x+3y=19
4x+3(9)=19
4x+27=19
minus 27 both sides
4x=-8
divide 4
x=-2
(x,y)
(-2,9)
Answer:
It is 6%
Explanation:
The stock that is bought by Rick Mendez: 5,000
Own money used to buy: 2,500
Borrowed money: 2,500
Interest on borrowed money : 30
Brokerage commissions: 300
The stock is sold after one month: 5,650
Now first calculate the net profit = Selling price of stock – cost price of stock – Interest on borrowing – commission
5,650-5,000-30-300=320
Now calculate the rate of return = Net profit / cost of stock
320/5,000=.06
.06 or 6%
<span>If M is the midpoint of CD, CM = 2x+3 and MD = 3x-6, then:
MD = CM
3x - 6 = </span>2x + 3
3x - 2x = 3 + 6
x = 9
CM = 2x+3 = 2*9+3 18+3 = 21
MD = CM = 21
CD = CM + MD = 21 + 21 = 42
