The <em><u>correct answer</u></em> is:
negative six and thirty-three fortieths
Explanation:
To multiply (2 5/8)(-2 3/5), we first change each mixed number to an improper fraction. To do this, we multiply each whole number by the denominator and add the numerator:
(2*8)+5 = 16+5 = 21; this makes 2 5/8 = 21/8
(2*5)+3 = 10+3 = 13; this makes -2 3/5 = -13/5
This gives us
(21/8)(-13/5) = (21*-13)/(8*5) = -273/40
40 will go into 273 6 times; this gives us the number -6. There is then 270-240 = 33 left over; this gives us 33/40, and a total of -6 33/40.
Let's solve your equation step-by-step.
1/3x^2=16
Step 1: Divide both sides by 1/3.
1/3x^2 ÷ 1/3 = 16 ÷ 1/3
x^2=48
Step 2: Take square root.
x=±√48
x=4√3 or x=−4√3
Answer: x=4√3 or x=−4√3
