Answer: 10.1
Step-by-step explanation:
Step 1: 1,000 is greater than 100 but smaller then
Step 2: 10,000 1,000 is divided by 10,100 which =10.1
Step 3: and 10.1 is less than 100 greater than 1
When you subtract flip the signs of the second set.
2x^2+5-4x+3
Now combine like terms
2x^2-4x+8
Final answer: B
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.
