Step-by-step explanation:
Given : The formula for the area of a trapezoid with altitude k and bases m and n is 
We have solve for m .
Consider the given formula 
Multiply both side by
, we have,

Now subtract n both side, we have,

Thus, 
0.84 is 10 times as much as 0.084
Answer:

Step-by-step explanation:
We know we have to write an algebraic equation for the sentence - so "translate" the phrases of the sentence step-by-step. Let the unknown number be represented by the variable n, as the question states.
Start with the phrase "the sum of a number and 4.4." A sum comes as a result of adding numbers together - therefore the first part of the equation must be
.
Next, the sentence says "is 8.1." The "is" indicates that the expression we just wrote equals something, so that number must be 8.1. Therefore, the whole equation must be
.
2 bags of corn chips + 8 bags of potato chips + 5 bags of ??? = 15 bags total
2/ (5+8+2) = Probability
