Answer:
x= -7
Step-by-step explanation:
1/2(4-6x)=23
Take1/2 of the numbers in the (). It will be 2-3x.
2-3x=23 subtract 2 from both sides to get x by itself
-3x=21 now divide the 21 by -3
x= -7
140/15.5 = unit rate
140/15.5 = around 9.03
Average swimming rate: 9.03 meters per second
Assume that solution with 20% and 50% salt is x and y gallons respectively.
Therefore,
x+y = 300 => y=300-x
Additionally
20x+50y = 300*41 = 12300
Substituting for y
20x+50(300-x) = 12300 => 20x+15000-50x = 123000 => -30x = -2700
x= 90 gallons
y= 300-x = 300 - 90 =210 gallons
