Answer:
√99 is irrational
Step-by-step explanation:
The equation that can be used to find the number of emergency kits that Lexi packs is 4x=120.
Given that Lexi packs 4 water bottles into each kit and total 120 water bottles are packed by Lexi.
We are required to find the equation which can be used to find the number of emergency kits that Lexi packs.
Equation is like a relationship between two or more variables that are expressed in equal to form.Equation of two variables look like ax+by=c. It may be linear equation,quadratic equation, cubic equation and many more depending on the power of the variable that is present in that equation.
let the number of emergency kits that Lessi packs be x.
The equation which will shows the total number of bottles be:
=(Number of bottles in 1 kit)*x
Equation will be:
4x=120
Hence the equation that can be used to find the number of emergency kits that Lexi packs is 4x=120.

Answer:
B
Step-by-step explanation:
Simplify the numerator and denominator of the fraction, that is
- 
Multiply the numerator/denominator of the first fraction by y
Multiply the numerator/denominator of the second fraction by x
- 
= 
Similarly
+ 
Multiply numerator/denominator of the first fraction by x
Multiply numerator/denominator of second fraction by y
+ 
= 
To perform the division
leave the fraction on the numerator
Change division to multiplication
Turn the fraction on the denominator upside down, thus
× 
Cancel xy on the numerator and denominator
= 
← factor 2 out of each term on the numerator
= 
→ B
