Simplify £2.50 : 60p

Answer:

Here we will simplify 2/50 to its simplest form and convert it to a mixed number if necessary.

In the fraction 2/50, 2 is the numerator and 50 is the denominator.

When you ask "What is 2/50 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.

We do this by first finding the greatest common factor of 2 and 50, which is 2.

Then, we divide both 2 and 50 by the greatest common factor to get the following simplified fraction:

1/25

Therefore, this equation is true:

2/50 = 1/25

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.

1/25 = Proper Fraction

Which statement is true about f(x) = –6|x + 5| – 2?
Ad libitum [116K]
The graph of f(x) opens upward

For the values of x < -5 the function is a line with negative slope, for the values of x > - 5 the function is a line with positive slope.

The two lines intercept in the point (-5,-2). That is the vertex of the function; a minimum value. So, all the other points are above the line y = -2.

Evaluate.<br> 6[5(3-9)-1]+2 the answer of this divided by the answer of this one 7(8-2)+4
Snowcat [4.5K]


According to PEMDAS, these are the steps for evaluating this equation -

3-9=-6

-6 x 5 = -30 - 1 = -31

-31 x 6 = -186, + 2 = -184

Now our first answer is -184 (I think this is correct)

Next thing we'll do is the second equation

8-2 = 6

6 x 7 = 42

42 + 4 = 46

Now, we can divide :)           -184 / 46 equals -4

Hope this helps :D!
