Answer:

The common difference is -9 1/8

Step-by-step explanation:

we know that

In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, and this constant is called the common difference

Let

a_1=-2

a_2=-\frac{17}{3}-\frac{13}{3}-1\frac{1}{8}

a_2=-\frac{30}{3}-\frac{1*8+1}{8}

a_2=-10-\frac{9}{8}

a_2=-\frac{89}{8}

a_2-a_1=-\frac{89}{8}-(-2)=-\frac{89}{8}+2=-\frac{73}{8}=-9\frac{1}{8}

therefore

The common difference is -9 1/8

A 2 -gallon container of window costs 31.36. what is the price per cup
irinina [24]

Answer:

0.98 $/cup

Step-by-step explanation:

The final answer asks for price/cup, as "per" means "divided by".

So, our final units will be in $/cup.

We are given that for every 2 gallons, it will cost $31.36.

In order to get from gallons to cups, we need to convert units.

In 1 gallon, there are 16 cups.

So, our conversion factor will be 16 cups/1 gallon.

\frac{31.36}{2} *\frac{1}{16} \\\\= 0.98$/cup

Important things to note:

- With these types of problems, it makes it much easier if you just figure out what units you need in the final answer, and then use conversions and dimensional analysis to get the answer
