Explain how you know Elena made a mistake based on her solution.
Elena is trying to figure out how many movies she can download to
her hard drive. The hard drive is supposed to hold 500 gigabytes
of data, but 58 gigabytes are already taken up by other files. Each
movie is 8 gigabytes, Elena wrote the inequality 8x + 58 2 500 and
solved it to find the solution x > 55.25.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

0.038

step-by-step explanation:

the equation is not included but the answer is (1.50, 2.00, 2.75)
