Answer:
I don't think you are doing anything wrong. Just ignore it and write the repeating decimal. If you're asked to do it, round it up instead.
Hello!
We know that from midnight to 6am the temperature went up 8° and at 6am it was -21°
To find what it was at midnight we have to work backwards
Since it went up we have to subtract 8 from -21
-21 - 8 = -29
The answer is -29°C
Hope this helps!
Let x = pounds of $12 per pound coffee
then
20-x = pounds of $9 per pound coffee
.
12x + 9(20-x) = 10(20)
12x + 180 - 9x = 200
3x + 180 = 200
3x = 20
x = 20/3
x = 6 and 2/3 pounds of $12 per pound coffee
.
Amount of $9 per pound coffee:
20-x = 20-20/3 = 60/3 - 20/3 = 40/3
or
13 and 1/3 pounds of $9 per pound coffee
There’s no picture but three ordered pairs for the equation would be: (0,2/3), (1,3), (2,16/3).
