Answer:
x≥2
Step-by-step explanation:
Let's solve your inequality step-by-step.
12−7x≤−2
Step 1: Simplify both sides of the inequality.
−7x+12≤−2
Step 2: Subtract 12 from both sides.
−7x+12−12≤−2−12
−7x≤−14
Step 3: Divide both sides by -7.
−7x/−7 ≤ −14/−7
x≥2

Answer:
4 liters of 5% and 16 liters of 17.5%
Step-by-step explanation:
Let quantity of 5% be x liters and of 17.5% be y liters
x+y=20 hence y=20-x
Introducing percentages
0.05x+0.175(20-x)=0.15*20
0.05x+3.5-0.175x=3
-0.125x=-0.5
Therefore, y=20-x=20-4=16
You need 4 liters of 5% and 16 liters of 17.5% to achieve 20 liters of 15% acid solution
