Answer:
x = -2
Step-by-step explanation:
2(x - 5) - 5x = -4
Distrubute the 2 into the parentheses
2x - 10 - 5x = -4
Add 10
+10 +10
2x - 5x = 6
Simplify
-3x = 6
Divide
÷ -3 ÷ -3
x = -2
Answer:
13.79%
Step-by-step explanation:
A solution is made by dissolving 24 millimeters of saline in 150 millimeters of pure solution
Therefore percent of saline in the pure solution can be calculated as follows
= 24/24+150 × 100
= 24/174 ×100
= 0.1379 ×100
= 13.79%
Hence the percent of saline in the pure solution is 13.79%
