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:
He needs a score of 88 on his last test.
Step-by-step explanation:
His mean score is the sum of all his scores dvided by the number of tests. Mathematically, that is:
Zach took four biology tests and got scores of 83, 86, 91, and 77. He needs to complete one more test.
In total there are 5 tests, so 
His scores are 83, 86, 91, 77 and x. In which x is his score on the last test. So 
If he wants to get an average of 85 on all fve tests, what score does he need on his last test?
This is X when M = 85. So
He needs a score of 88 on his last test.
1/3 ounce - 1/4 pound is 4 ounces and then you just divide by 12, resulting in .3333333333 or in other words, 1/3
Answer:
b. 30
Step-by-step explanation:
70 + (x + 80) = 180
180 - 70 - 80 = 30
x = 30
<C,<F,<G. you have to look at the sides tgat match <B
