Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question. In this lesson, I'll concentrate on the "plug and chug" aspect of evaluation: plugging in values for variables, and "chugging" my way to the simplified answer.
Step-by-step explanation:
The value of 5 into 756 is .0066, or 0.66%. You can write this out as shown, and draw it out using traditional division.
30+1.95x=7.95x
so, 6x=30
x=5
