Answer:
p : q : r = 10 : 4 : 3
Step-by-step explanation:
Expressing the ratio in fractional form
=
( cross- multiply )
4r = 3q ( divide both sides by 4 )
r = q =
× 2 =
Then
p : q : r
= 5 : 2 : ( multiply all parts by 2 )
= 10 : 4 : 3
the length of the rectangle is 10ft
Step-by-step explanation:
let the length = x
width = x - 4
area = length X width
so, according to the problem
x(x-4) = 60
or, - 4x = 60
or, -4x -60 = 0
or, - 10x + 6x -60 = 0
or, x(x-10) +6(x-10) =0
or, (x-10)(x+6) = 0
x = 10 ( x= -6 for length this value is not possible)
so length is 10ft
width = 10 - 4 = 6ft
Answer:
This is the fraction 2x/15 which can be read as 2x over 15
=====================================================
Work Shown:
Divide over
to get
You can think of it as dividing 14x^2 over 7x and that results in 2x. Then you place that result (2x) over 15 to end up with 2x/15
