Answer:

x=2

Step-by-step explanation:

1*x+30=6x+20

Multiply 1*x=x

x+30=6x+20

Subtract 30 from both sides:

x+30-30=6x+20-30

Simplify:

x=6x-10

Subtract 6x from both sides

x-6x=6x-10-6x

Simplify:

-5x=-10

Divide both sides by -5

-5x/5=-10/-5

Answer:x=2

The following invoice contains the notation "2/10, n/30." Determine the price of the order. An invoice dated December 27 lists a
irinina [24]

Answer:

The problem statement tells you the order price is $885.00.

The balance to be paid on 5 Jan is 2% less than that, $867.30.

Step-by-step explanation:

The notation "2/10, n/30" means a discount of 2% is applied if the invoice is paid within 10 days, but the net amount is due within 30 days in any event. 10 days after 27 Dec is 6 Jan, so a payment on the 5th of January is subject to the 2% discount.

After 2% is subtracted from 100% of the invoice amount, 98% percent remains. The payment need only be ...

... 0.98 × $885.00 = $867.30

<em>_____</em>

<em>Comment on problem wording</em>

Your problem statement says, "Determine the price of the order." It also says, "... an order priced at $885.00." The determination asked for is found in the problem statement: $885.00. If that is the required answer, it would place this problem in the "trick question" category, as the notation and payment date information are clearly unneeded.

We suspect the problem really wants you to determine the amount to be paid for the order when payment is made on January 5. Unfortunately, that is not what is asked for.

Write the equation 4X -3Y = 12 in the form Y =MX +b
USPshnik [31]

Answer:

Step-by-step explanation:

we have 4x-3y=12

-3y=-4x+12

-y=-4x+12/3

we have 12=3*4  so we remove 3 that is up and 3 that is down

-y=-4x+4

then we get y=+4x+4

Newton's Law of cooling is
T(t)=T_{a}+(T_{0}-T_{a})e^{-0.1947t}
where
T(t) = temperature of the body after t hours, 80 °F
T_{a} =  ambient temperature, 65 °F
T_{0} = normal body temperature, assumed to be 98.6 °F

The elapsed time since death is obtained from
65+(98.6-65)e^{-0.1947t|} = 80
33.6e^{-0.1957t}=15
-0.1947t=ln \frac{15}{33.6}
t= \frac{ln(15/33.6)}{-0.1947} =4.142

4.142 hours before 2 am is 9:52 pm (the previous day) approximately.

Answer:  9:52 pm the previous day.
