Answer:
12X^-3
Step-by-step explanation:
12X^15 / 3X^12 = 0. The properties of exponents would say that we have to subtract the exponents in division, but we need the same bases first. In order to get the bases the same we need to divide both sides by 1/4. That will make 12 stay 12 and 3 become 12. Now we subtract the exponents using the properties of exponents with the same base. We end up left with 12x^-3.
I apologize if I made an error. I would be careful since I'm not to sure about my answer myself.
Maybe you should work on starting you're sentences.
She can serve 80 4-oz servings.
1 gallon = 4 quarts
1 quart = 2 pints
1 pint = 16 ounces
1 quart = 2 pints = 2(16) = 32 ounces
1 gallon = 4 quarts = 4(32) = 128 ounces
2 1/2 gallons = 2.5(128) = 320 ounces
320 ounces/4 ounces per serving = 80 servings.
Answer:
8750
Explanation:
There are 5/5 math teachers in the university. 3/5 of them did not want to become math teachers which means 2/5 of the math teachers is equal to 3500.
3500=2/5
divide 3500 by 2 to get 1/5 of the math teachers.
3550/2=1750
1750 is 1/5 of the math teachers.
multiply 1750 by 5 to get 5/5 of the math teachers
1750*5= 8750
2/1 = (8x-2)/9
2=(8x-2)/9
18=8x-2
20=8x
x=8/20
x=2/5
