One minute is sixty seconds.

So we can do 6 times 60 and the answer comes out to 360. It took him 360 seconds to complete the puzzle.

What is product of x/3 and 6/x when x=0 ? <br>A.2 <br>B.18 <br>C.2/x^2<br> D.18/x^2

Ahat [919]

Answer:

A) But if anyone thinks this they should go back to preschool

Step-by-step explanation:

On any other value of x you would take the numerators and denominators and multiply them across:

$\frac{x}{3}*\frac{6}{x}=\frac{x*6}{x*3}=\frac{6}{3} =2$

But, this literally does not make since considering the fact that you cannot divide any value by zero. Try it, it won't work. If we plug these into a trusty dusty calculator, we get this:

$\frac{0}{3}=0\\\\\frac{6}{0}=DOMAINERROR$

0*DOMAINERROR= You can't do it.

There are other reasons why you can't divide by zero, I would suggest looking them up on YT and learning about them.

I would answer A, but the person who wrote this question just wasn't focusing when they wrote the question.

You cannot assume the angles add to 90, but you know since BD is an angle bisector that ABD is equal to DBC, or x-5=2x-6

x=1. this is the correct solution to the equation but gives negative angles when plugged in which isn't possible. there must be something wrong work the question

Alexus [3.1K]

Answer: x = 0; x=10

Step-by-step explanation:

$\frac{x+2}{x-4} *\frac{3x}{x+4}\\ \\x+2(x+4) = x-4(3x)\\x^{2} +2x+ 4x + 8 = 3x^{2} -12x\\2x+4x+12x =3x^{2} - x^{2} \\20x= 2x^{2} \\10x = x^2\\x=0\\x=10$

Hope this helps!

Easy first cover kilograms into grams 1kg=1000g. resulting in 10,000g dividing that by the weight of the oranges getting 10,000/200=50 so the answer is 50 oranges. (assuming they all weigh the same)
