Michelle used a scale to measure to rocks. one rock weighs 7/10 pound. the other rock weighs 25/100 pounds. what fraction represents the total weight, in pounds, of both rocks?

7/10 is equal to 70/100. 70/100+25/100 is 95/100, or 19/20

The point (5, 10) will work for the rule y=x+5.y= 10 x= 510=5+510=10therefore the ordered pair (5, 10) works for the rule

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
