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.
Answer:
(x - 1)^2 + (y - 4)^2 = 4^2
Step-by-step explanation:
Here you're given the center: (1, 4) : (h, k), and so the equation becomes
(x - 1)^2 + (y - 4)^2 = r^2
To find r^2 and r, substitute 5 for x and 4 for y, obtaining:
(5 - 1)^2 + (4 - 4)^2 = r^2
Then: 4^2 = r^2, and so r must be 4. The final version of the equation is
(x - 1)^2 + (y - 4)^2 = 4^2
Answer:
(x − 2)×(3x+1)
Step-by-step explanation:
We can use this method:
All I did is Subtracting x then adding x which will not affect the result because -x + x = 0
14=17-x
-3=-x
The unknown number is X and u simplify first
Answer:
no, he is not correct
