Answer:
The variable is x.
The value of the variable is 9.2.
Step-by-step explanation:
The equation shows the variable x multiplied by 3.5 with the result of that multiplication being 32.2. In order to solve for x, you must "undo" that multiplication.
The definitions of the multiplicative inverse and of the multiplication identity element tell you how to do that. The multiplicative inverse of a number is its reciprocal: the multiplicative inverse of 3.5 is 1/3.5. Multiplying a number by its multiplicative inverse gives a result of 1. Here, that means ...
3.5 × (1/3.5) = 1
The property of the multiplicative identity element (1) is that anything multiplied by that is just that thing:
x · 1 = x
So, to solve this equation, you multiply both sides by the multiplicative inverse of 3.5:
3.5x = 32.2
(1/3.5)(3.5)x = (1/3.5)(32)
1x = 9.2 . . . . . carry out the multiplication
x = 9.2 . . . . . . recognize 1x = x
___
You will recognize that multiplying by 1/3.5 is the same as dividing by 3.5. In other words, we solve this equation by dividing it by the coefficient of x.

X= 14
Step-by-step explanation:
Answer:
Gross profit formula= 3x
x= number of units sold
Step-by-step explanation:
Giving the following information:
Unitary variable cost= $2
Selling price per unit= $5
<u>To calculate the profit earned, we need to use the unitary contribution margin formula</u>. The contribution margin is a product's price minus all associated variable costs (sales- variable costs), resulting in the incremental profit earned for each unit sold.
Unitary contribution margin= 5 - 2 = 3
<u>Now, the profit formula:</u>
Gross profit formula= number of units*unitary contribution margin
Gross profit formula= 3x
x= number of units sold
Answer:
x = 122
Step-by-step explanation:
x = 122 because of alternate interior angles
