I need help I don't understand at all.
Shalnov [3]
Let's solve your equation step-by-step.

1/4x - 2 = -6 + 5/12x

Step 1: Subtract 5/12x from both sides.

So now the problem is: -1/6x - 2 = -6

Step 2: Add 2 to both sides

So now the problem is -1/6x = -4

Step 3: Multiply -6 to both sides

Now you have x alone and 24

Answer: x = 24

Does a two-digit number exist such that the digits sum to 9 and when the digits are reversed the resulting number is 9 greater t
Alexeev081 [22]

The answer would be "t + u = 9 and 10t + u = 10u + t - 9". This can be found if you replaced t with 4 and u with 5. Adding the 2 digits would give you 9, and using the formula "10t + u = 10u + t - 9". Replace t and u with 4 and 5 then simplify. 10*4 + 5 = 10*5 + 4 - 9. Simplifying you'd get 45 = 54 - 9 or 45 = 45 which make the statement true. Thus making "t + u = 9 and 10t + u = 10u + t - 9" the answer.

I hope this helps!

Using technology, determine the monthly payment on a 35 month loan of $28,000 at 8.1% compounded annually. Round you answer to t
Crank
Present Value of an annuity is given by the formular
PV = P(1 - (1 + r)^-n)/r; where PV = $28,000, r = 0.081/12 = 0.00675, n = 35 and P is the periodic (monthly) payment.

P = PVr/(1 - (1 + r)^-n) = (28,000 x 0.00675)/(1 - (1 + 0.00675)^-35) = 189/0.2098 = 900.90

Therefore, the monthly payment is $900.90
