Solve for x
1 answer:
Answer:
Option C. x=-3
Step-by-step explanation:
we have
----> inequality A
solve for x
subtract 60 both sides
Divide by -15 both sides
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
The solution of the inequality A is the interval [-3,∞)
we have
----> inequality B
Solve for x
subtract 11 both sides
Divide by 14 both sides
The solution of the inequality B is the interval (-∞,-3]
The solution of the system is
(-∞,-3] ∩ [-3,∞) =-3
therefore
The solution is x=-3

So... the radiator has 15 liters of 70% antifreeze.. but needs an 80% antifreeze
well, so, you need to drain some and put some with higher percentage, seems to be, you will end up at the same 15 liters, possible the radiator's capacity, of 80% antifreeze
so, the same amount going out, of 70% is the same amount going in, of 100% antifreeze
now.. let's use the decimal format for the percents, or 70% is 70/100 or 0.7 and so on
so.. let's subtract, from the current solution, 0.7x and add 1x or x, our antifreeze concentration amount, should be 12 though
10.5 - 0.7x + x = 12
solve for "x"
