The scientific notation for 5390000000000 = 5.39 x 10^12
Answer:
3x + 2y = 38, 3a + 2b = 38
Step-by-step explanation:
An equation may be defined as a statement that shows two mathematical expressions to be equal. It is to equate one thing to another thing.
In the context, two different equations for the situations are :
i). Let the shirt be represented by x
And the socks be represented by y
Therefore, according to the question,
3x + 2y = 38
ii). Let the shirt be represented by a
And the socks be represented by b
Therefore, according to the question,
3a + 2b = 38
With ellipse the equation to find c or the distance from the center to the foci is c^2 = a^2 - b^2. So if you plug those numbers in you get:
c^2 = 25 - 9
c^2 = 16
c = 4
The distance from the center to each foci is 4
Answer:
b ) a^7/b^6 is the correct answer
Answer:
7.5 days
Step-by-step explanation:
7.5 days because it is 30 percent off then the the sale The sale decreases 20 percent making it 10% off and if the price is 75 you'd have to divide it by 10 and you would get 7.5 days
