1. In algebra, like terms are terms that have the same variables and powers.

2. What is combining like terms? We call terms "like terms" if they have the same variable part.

3. Polynomials form a system similar to the system of integers, in that polynomials are closed under the operations of addition, subtraction, and multiplication. CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial. ... Polynomials are closed under subtraction.

PLEASE HELP ME.....
Virty [35]

Answer:

They would meet each other at 01 : 24 PM.

Step-by-step explanation:

  • Erik took a trip to see his friend Mike who lives 308 miles away.
  • He left his place at 10 AM driving at 70 mph.
  • In 2 hours, his friend Mike left his place driving towards Erik at an average speed of 50 mph.

As Erik left his house at 10 AM driving at 70 mph and in 2 hours, his friend Mike left his place driving towards Erik at an average speed of 50 mph. It means

Erik left his place at 12:00 PM noon.

so, at 12:00 PM Erik had already traveled:

                                                                      2\times 70=140\:\:miles

Miles left =308-140=168\:\:miles

Let 't' be the time when they meet

so

70t\:+\:50t\:=168

120t=168

\mathrm{Divide\:both\:sides\:by\:}120

\frac{120t}{120}=\frac{168}{120}

t=\frac{7}{5}

so

t=\frac{7}{5}=1.4\:\:hours

or 1 hour and 24 minutes after 12:00 noon

i.e.

12\:+\:1.4\:=1\:O'clock\:+\:24\:minutes

Therefore, they would meet each other at 01 : 24 PM.

Please help me with question 4!
Minchanka [31]

Answer:

I think that there might be some complex differential equation

stuff going on here if this were in the real world, but for the sake of this problem... may I suggest that the tank is filling up  at a rate of

1/8 of a tank per hour...

it is evaporating at a rate of 1/12 tank per hour

you can subtract the rates

1/8 - 1/12 = 12/96- 8/96 = 3/96 = 1/32 tank/hr

so to fill the tank it should take 32 hours...

I think the logic and math work... lets see if someone else will verify this analysis?
