If 3x − y = 12, what is the value of 8^x/2^y?
ivanzaharov [21]

Answer:

A

Explanation:

Let's solve the equation to be written as y in terms of x by adding y to and subtracting 12 from both sides:

3x - y = 12

3x - 12 = y

Now, replace y in the other expression that we want to find (8^x/2^y) with this expression 3x - 12:

8^x/2^y

8^x/2^{3x-12}

Now, we also know that 8 = 2³, so substitute 2³ for 8 in the expression:

8^x/2^{3x-12}

(2^3)^x/2^{3x-12}=2^{3x}/2^{3x-12}

Remember that when dividing powers with the same base (in this case, the common base is 2), the result will be a single power whose exponent is the difference of the other two powers. Here, then we have:

2^{3x}/2^{3x-12}=2^{3x-(3x-12)}=2^{12}

Thus, the answer is A.

padilas [110]

Mr Reams uses 10 cups of paint to fill the small dishes, therefore, the amount of paints left in the bowl is 2 cups.

<h3>How to convert ounces to cups?</h3>

He mixes 12 cups of paints in a large bowl.

He uses the paint to fill 40 small dishes with 2 fluid ounces of paint each.

1 small dish = 2 fluid ounces

40 small dishes = 80 fluid ounces

Therefore,

1 fluid 0unces = 0.125 cups

80 fluid ounces = ?

cross multiply

amount of paint filled = 80 × 0.125 = 10 cups

Therefore, the amount of cups pf paint Mr Reams have left in the bowl is 12 cups - 10 cups = 2 cups.

If ru-ping earns an a in science, an a in math, and c in English, what is her gpa
nataly862011 [7]
Assuming all subjects have the same/equal credits, A is equivalent to 4, C is 2.

So, (4+4+2) / 3

n = (4+4+2) / 3
n = 10 / 3
n = 3.333333
n = 3.33

Hope this helps. :)
