List of given options
Required
Which will correctly take 3 to fill the blank
Represent the blanks with x
Option A:
[tex]x : 4 = 12 : 16[/tex]
Convert to fractions
[tex]\frac{x}{4} = \frac{12}{16}[/tex]
Multiply through by 4
[tex]4 * \frac{x}{4} = 4 * \frac{12}{16}[/tex]
[tex]x = \frac{48}{16}[/tex]
[tex]x = 3[/tex]
Option B:
[tex]1 : 5= x : 15[/tex]
Convert to fraction;
[tex]\frac{1}{5} = \frac{x}{15}[/tex]
Multiply through by 15
[tex]15 * \frac{1}{5} = \frac{x}{15} * 15[/tex]
[tex]15 * \frac{1}{5} = x[/tex]
[tex]3 = x[/tex]
[tex]x = 3[/tex]
Option C:
[tex]x : 1 = 12 : 3[/tex]
Convert to fraction
[tex]\frac{x}{1} = \frac{12}{3}[/tex]
[tex]x = 4[/tex]
Option D
[tex]15:x = 3:1[/tex]
Convert to fraction
[tex]\frac{15}{x} = \frac{3}{1}[/tex]
Cross Multiply
[tex]3 * x = 15 * 1[/tex]
[tex]3 * x = 15[/tex]
Divide through by 3
[tex]x = 5[/tex]
From the above calculations.
Option A and B can be filled with 3

Answers
Answer:
x = 20
Step-by-step explanation:
For the lines to be parallel, then (3x + 20) and (3x) are alternate angles and congruent, thus
3x = 2x + 20 ( subtract 2x from both sides )
x = 20

Answer:
(3a+4)(9a^2-12a+16)
Step-by-step explanation:
It's a perfect square :)
The factors of the given polynomial are (4+3a)(9a²-12a+16)
What is polynomial?A polynomial is defined as an expression which is composed of variables, constants and exponents, that are combined using mathematical operations.
Given that, a polynomial, 64+27a³
Using identity : a³+b³ = (a+b)(a²-ab+b²)
We get,
= (4+3b)(4²-4x3a+(3a)²)
= (4+3a)(16-12a+9a²)
Hence, the factors of the given polynomial are (4+3a)(9a²-12a+16)

What is the slope of a line perpendicular to the line whose equation is 6x-15y=270
Answers
Answer:
m= -2 1/2
Step-by-step explanation:
First, let's put the equation into slope intercept form.
6x-15y=270
-15y=-6x+270
y=6/15x+270
For two lines to be perpendicular, their slopes must be opposite reciprocals.
m=-15/6 or m= -2 1/2
Answer:
slope = - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
6x - 15y = 270 ( subtract 6x from both sides )
- 15y = - 6x + 270 ( divide all terms by - 15 )
y = [tex]\frac{-6}{-15}[/tex] x - 18, that is
y = [tex]\frac{2}{5}[/tex] x - 18 ← in slope- intercept form
with slope m = [tex]\frac{2}{5}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{5} }[/tex] = - [tex]\frac{5}{2}[/tex]
