Answer:
-18b + 66
Step-by-step explanation:
-6 + 9(8 - 2b)
-6 + 72 - 18b
Answer: 66 - 18b
-6+9(8-2b)
You will open the bracket first. This will be:
= -6 + 9(8-2b)
= -6 + 72 - 18b
= 66 - 18b
4/2
The proportion given in the problem statement ...
... 3 days/(1 gallon) = 5 days/(x gallons)
can be multiplied by (x gallons/day) to get ...
... 3x = 5
fwe
9√2 is squared first.
so its 162.
now according to Pythagoras theorem,
x2+x2=162
2x^2= 162
x^2= 162÷2
x^2= 81
x= √81
x=9
