Given p : q = 5 : 2 and q : r = 4 : 3, find the ratio of p : q : r​
yaroslaw [1]

Answer:

p : q : r = 10 : 4 : 3

Step-by-step explanation:

Expressing the ratio in fractional form

\frac{q}{r} = \frac{4}{3} ( cross- multiply )

4r = 3q ( divide both sides by 4 )

r = \frac{3}{4} q = \frac{3}{4} × 2 = \frac{3}{2}

Then

p : q : r

= 5 : 2 : \frac{3}{2} ( multiply all parts by 2 )

= 10 : 4 : 3

Let \[f(x) = \frac{3x - 7}{x + 1}.\]find the range of $f$. give your answer as an interval.
ra1l [238]
Hello :
let : y=  \frac{3x-7}{x+1}
calculate : x ......x <span>≠ -1 
</span>y(x+1) = 3x-7
yx+y =3x-7
yx-3x = -y-7
x(y-3) = -7-y
x =  \frac{y+7}{3-y}
the inverse function is : g(x) =  \frac{x+7}{3-x}
domain of : g  is the range of : f
as an interval : ]-∞: 3 <span>[</span>U ]3;+∞[

4/5 os the fourth multiple of what unit fraction?
Leviafan [203]
I  do believe it is the 4th multiple of 1/5 because the unit fraction is 1/5, so if you multiple 1/5 times 4, i believe you get 4/5.
