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
3.057.02 is your answer to this question.
I think the answer would have to be D. $0.90.
59,970-58,800=1,170
1,170/52=22.5/25=0.90
Answer:
C is the only choice that forms a proportion
Step-by-step explanation:
a. 24/31, 20/27

c. 16/5, 64/20
(both 16/5 *4 = 64/20) so it works
d. 6/4 , 15/10
(similar situation to choice b the ratio wont work since 6 doesn't go into 15)
Answer: y=-x+8
