Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em> - <em>y-intercept</em>
We have

Substitute:

To express a decimal number (with a finite decimal expression) in a fraction, you work like this: the numerator is the number without decimale separator (you simply pretend it's not there), while the denominator will be
, where n is the number of digits after the decimal separator.
So, in your case, the number without decimal separator is 53, and you have two digits after the decimal separator, so the fraction will be
which is irreducible.
12 is composite number. 12=1x12 and many more but. Try 1,2,3,4,6
Answer:
6
Step-by-step explanation:
5/6 of 30 = ?
5 x
---- = ----
6 36
36 x 5 = 180
180/6 = 30
That means 30 singers are boys.
36 - 30 = 6 (the number of girls)
X=30
Put in proportions x/45 = 18/27.
Cross multiply and get 27x= 45 x 18
Or 27X = 810.
Next, divide by 27 on both sides to get X=30.
