Answer:
3 deg C
Step-by-step explanation:
Start with -8 deg and add 11 deg.
-8 + 11 = 3
Answer: 3 deg C
4/3
40/30
60/45
Simply multiply or divide both the 20 and the 15 to get an equivalent ratio.
9x–42=5 is x = 11.
<u>Step-by-step explanation:</u>
9x- 42 = 5...
When we put x = 9
then we will get 81 - 42 =39
put x = 10 then
9(10) - 42 = 90 - 42 - 48
put x = 11
then 9(11) - 42 = 99-42 = 57
So x = 11 is the answer.
