Answer: Hello

1)
(2x(x-3))/((x-1)(x+1))*(x(x-1))/((x-3))*(3(x+1))/(1)
=(6x(x+1))/(x+1)=6x

2)
(2(x-1)-(x+1)-(x+2))/((x-1)(x+1)(x+2))=(-5)/((x-1)(x+1)(x+2))

future value = P × (1+ i)t Kate wants to have $25,000 in 16 years. How much does she need to invest if the interest rate is 6 percent per year?

Answers

If Kate wants $25,000, then that's the future value.
i is the rate of change, which is 6% in this case, which is rewritten as 0.06.
P is the starting value, or what she has to originally put in, which is what we need to find.
You put times t but it's actually to the power of t, which is time.
The time in this problem is 16 years, so t is 16.
Let's rewrite the equation with the plugged in values.
25,000 = P(1 + 0.06)^16
Now simplify:
25,000 = P(1.06)^16
25,000 = P(1.06^16)
25,000 = P(2.54)
How do you find P?
Isolate the variable!
To do this, divide both sides by 2.54.
25,000 / 2.54 = 9842.52
So that means she needs to invest an original amount of $9,842.52 if she wants to have $25,000 in 16 years with a 6% interest rate per year.

Now just check your work:
25,000 = 9842.52(1 + 0.06)^16
25,000 = 9842.52(1.06^16)
25,000 = 9842.52(2.54)
25,000 = 25,000
It works!
So $9,842.52 is the correct answer.

You got the following scores on 3 tests: 84, 82, 98. What score must
you get on the 4th test if you want to
average a 90% for the 4 tests?
A. 94
B. 95
C. 96
D. 97
E. 98

Answers

Your answer is c. 96
I know this because if you go on the calculator and add up 84+82+98+96 its equals to 360 and 360 divided by four (since there are now four marks including the mark you need to get on the next test) and that equals to 90. 

(in other terms)
84+82+98+96=360
360÷4=90
therefore, you need to get a score of 96 on your fourth test to receive an average of 90%

What is a down payment of 20 percent on a purchase price of $215,000

Answers

Answer:

Down payment is $43,000

Step-by-step explanation:

If purchase price of anything = $215,000

Down payment = 20% of the price

20% of 215,000

= (20)/(100) × 215,000

= 0.20 × 215,000

= $43,000

20% down payment on a purchase price of $215,000 is $43,000.

20% of 215,000......turn ur percent to a decimal...." of " means multiply
0.20(215,000) = 43,000

Elimination method

(4, ? )

what number is the ?​

Answers

The ? Is 11.


You add the equations to get rid of one variable, then you have 6x=24 then you divide both sides and you have x=4, then you substitute the given value of x and you are left with 5*4 - y = 9. And the solution or well possible solution is y = 11 which gives youuuuu. (x , y) = (4 , 11)
4 + y = 15....1
20 - y = 9.....2

....1*5
20 + 5y = 75....3

....3 - .....2
4y = 60
y = 15

the answer for (?) is 15
