How do you calculate 3 1/3 - 2 2/5?

2 answers:

8 0

First you have to get a common denominator, so multiply each fraction by the opposite fraction's denominator, but the whole number is not multiplied along with it.

3 1/3 * 5 = 3 3/15

2 2/5 * 3 = 2 6/15

Now you can subtract them

3 3/15 - 2 6/15
48/15 - 36/15
12/15

4/5 is the answer!

I hope that helps!

The equation of a circle is x2 − 4x + y2 + 8y − 29 = 0. what are the center and radius of the circle? enter your answers in the

uranmaximum [27]

$\text{The standard form of the circle:}\\\\(x-h)^2+(y-k)^2=r^2\\\\\text{h and k are the x and y coordinates of the circle}$

$\text{We have}\\\\x^2-4x+y^2+8y-29=0\\\\\text{use:(*)}(a\pm b)^2=a^2\pm2ab+b^2$
$x^2-2x\cdot2+y^2+2y\cdot4=29\ \ \ |+2^2\ \ |+4^2\\\\\underbrace{x^2-2x\cdot2+2^2}_{(*)}+\underbrace{y^2+2y\cdot4+4^2}_{(*)}=29+2^2+4^2\\\\(x-2)^2+(y+4)^2=49$
$\text{Answer: the center (2;-4), the radius}\ r=\sqrt{49}=7$
