Answer:
35 grams
Step-by-step explanation:
The ratio of zinc to copper is 3 to 11
A jar of chemical contains 385 grams if copper
Therefore the number of grams of zinc it contains can be calculated as follows
3/11= x/385
11x= 385
x= 385/11
= 35 grams
Hence the chemical contains 35 grams of zinc
There is no power of 4 that is to 0
They are selling the wrapping paper for $5 each and selling the foil wrapping for $7 dollars each.
39=5(5)+2(7)
57=3(5)+6(7)
Yes it could be simplified to 2 girls every 1 boy but what you have is correct and I agree because if you divide each side by the corresponding number so 24/4 and 12/2 the both equal 6 so I agree
