Answer:
She factored out a 4 from the equation.
Step-by-step explanation:
So our original equation is 12x + 4 = 20x - 12
Anika's first steep of her equation is 3x + 1 = 5x - 3
We know that the terms were not moved around, so the first step was likely multiplication or division.
We also see that a 4 has been factored out of the entire equation, like this:
12x + 4 = 20x - 12
4(3x + 4) = 4(5x - 3)
And these 4's cancel each other out.
So, I conclude that Anika's first step was dividing the entire equation by 4 or factoring out a 4 from the equation.
The conversion factor used to convert kilometer per hour to meter per hour is
<em><u>Solution:</u></em>
Given that average person's speed when riding a bike along a street is 18 kilometers per hour
To find: conversion factor used to convert the given speed to meters per hour
Given average speed = 18 km per hour
From the conversion parameters:
1 km = 1000 meters
or
So, we can use the above conversion factor to convert average speed into meters per hour
18 km per hour = 18000 meter per hour
So the conversion factor used to convert kilometer per hour to meter per hour is
Thus option C is correct. 1000 meters for 1 kilometers
