Answer: =−x−14
Step-by-step explanation:
2(x−4)−3(x+2)
Distribute:
=(2)(x)+(2)(−4)+(−3)(x)+(−3)(2)
=2x+−8+−3x+−6
Combine Like Terms:
=2x+−8+−3x+−6
=(2x+−3x)+(−8+−6)
=−x+−14

She is correct! This is so because 3 goes into .9 by .3 times. Hope this helped!
Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
= 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
= 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.
So it can be said that Marcia made a more concentrated salt solution.
