Answer:
x=-7
Step-by-step explanation:
so if you multiply two negative numbers you get a positive and and -7 * -3 is just doing 3*7 which is 21 and that is the answer to -3*-7 and 21 minus 5 is 16 so there´s that and hope this helps
so what you would do is 20 x 12 and see what you get and the subtract it from 900 and then see what number would take you to 900
If it costs $12.5 for every GB and we use 8 then 12.5*8=$100. So if our flat rate now is $70 we would loose 100-70=$30
So Maria would loose $30 a month if she pays per GB
5/3=1.6666 hope this helpssssssssssssssssssss
