Answer:
A unit rate is a rate where the second quantity is one unit , such as:
- $34 per pound
- 25 miles per hour
- 1 minute = 60 seconds
- 1 hour = 60 minutes
- Cost per litre.
Unit rate is used to compare quantities in which the second quantity is one.
Answer:

Step-by-step explanation:
move the 27 to the other side of the equation like this
use this equation and substitute it into the y value of the first equation
Answer:
x < -1
so its C
Step-by-step explanation:
Answer:
Division property
Step-by-step explanation:
The property which states that we can divide both side of the equation by the same non-zero number is called the division property of equality.
The goal of dividing an equation is to isolate the unknown variable on one side.
For example, let the equation be:
2×x=10
Since the unknown variable x is being multiplied by the number 2, to isolate the variable an inverse operation needs to be applied - division:
2×x<u>÷2</u>=10<u>÷2</u>
<u />
Careful! Never forget to write the same operation on both sides of the equation! When doing so, the solution of the equation stays the same, i.e. we get an equivalent equation.
