Ok, so she has 14 tickets and each ride cost 2 so that can be modeled with the following expression: x= 14-2y since she initially bought 14 tickets and 2 times the number of tickets she spends. To find the equivalent expression you could basically switch up the formula like so: 7*2-2y=x because you just need an equivalent expression, and you don't need to have such a different formula or anything like that. Hope I helped!
Answer:
6.53 (rounded to the nearest hundredth)
Step-by-step explanation:
You have a square with an area of 100 meters^2.
if you decrees a pair of opposite sides by 50%. you end up with a rectangle with the area of 50 meters^2.
then you increase the other pair of opposite sides by 50%. you end up with a rectangle with the area of 75 meters^2. OK now I see what I did wrong.
The correct answer is 75%
Answer:
The rate of the slower cyclist is

and that of the faster cyclist is

Step-by-step explanation:
We let x be the rate of the slower cyclist

From the question, the distance between the two towns is 253 and the time taken for the two cyclist to meet is 5 hours
so we can write the equation

We simplify to get the value for x




Hence the rate of the slower cyclist is

and that of the rate faster cyclist is

Monomial: expression with one term
Example: 6x
Binomial: expression with two terms
Example: 6x + 7
Trinomial: expression with three terms
Example: 8x^2 + 6x + 7
*any expression with four or more terms will be called a polynomial*
