Answer:
a
Step-by-step explanation:
D, irrational numbers. The opposite of squaring something is to find the square root and the square root of 20 is 4.4... 4.4 is an irrational number, therefore that is your answer. It wouldn't be rational because you can t write it as a fraction, 4.4 isn't a whole number so its not natural, and its not an integer because if <span>you have anything right of the decimal point that is not zero, it's not an integer.</span>
Answer:
The symmetric property
Step-by-step explanation:
The symmetric property of equality says we can exchange the sides of an equation and it will still be true..
In symbols, it says
If a = b, then b = a.
Your statement is
If 8x = 5y - 3z, then 5y -3z = 8x
Let a = 8x and b = 5y - 3z and your statement becomes
If a=b, then b=a
It is an example of the symmetric property of equality.
This is a typical mixture problem where using a table is the best thing.
pints juice % juice = total % juice
juice A x .70 = .70x
juice B 60-x .95 = .95(60-x)
total 60 .75 = 60(.75)
The last row gives you a total that you need to use, so do that multiplication to get 45. You now to need to add the last columns together for rows 1 and 2 and set them equal to 45: .7x +.95(60-x) = 45. When you do that math, you'll get that x = 48. This means that you need 48 pints of juice A and 60-48 pints of juice B, which is 12 pints.
