A unit rate compares a quantity to one unit of measure. You often see the speed at which an object is traveling in terms of its unit rate.
Evaluating each expression means to simplify the expression down to it's simplest form.
Step-by-step explanation:
you would divide 489 by 10 and then times that number by 15 and the divide 20 and get your answer that way
Answer:
54 cm
Step-by-step explanation:
Measures are proportional on a scale drawing:
drawing measure : actual measure = 6 cm : 3 m = x : 27 m
The value on the right of the x ratio, 27, is 9 times 3, so the value of x will be 9 times 6 cm.
54 cm on the blueprint represents an actual distance of 27 meters.
