Let 
and 
be the amounts of available alloy (AA) and pure magic steel that are used, so we also have
DA13 is supposed to contain 7% gold, 3% silver, and 90% steel, so that 2.7 kg of it is made up of
For each kg of the available alloy (AA), there is a contribution of 0.21 kg of gold, 0.09 kg of silver, and therefore 0.70 kg of steel; kg of it will contain 
kg of gold, 
kg of silver, and 
kg of steel. Each kg of magic steel of course contributes 1 kg of steel; kg of it will contribute kg of steel.
Then the dwarves need
• total gold: 
• total silver: 
• total steel: 
Solve for and . The first two equations are consistent and give 
, and substituting this into the third we find 
. So the dwarves must combine 0.90 kg of AA and 1.80 kg of magic steel.
(Picture attatched) so the asnwer rounded is .22. Basically u put the bigger divided by smaller and keep adding zeros after u subtract until it equals zero
Answer:
Clyde needs 2/3 cup more.
Step-by-step explanation:
The equation can be:
C = 2 - 2( 1 1/3 )
If Clyde is doubling the recipe, he will need 2 2/3 cups of flour. 2 2/3 minus 2 (the amount he has) will give you your answer.
so hmm check the picture below, thus the ball hits 19 feet of height twice, once on the way up, and once on the way down, at about 0.64 seconds and at 1.17 seconds.
