Answer:
30 pounds
Step-by-step explanation:
Amount of tin in first alloy + amount of tin in second alloy = amount of tin in mixture
0.15 (20) + 0.10 x = 0.12 (20 + x)
3 + 0.10 x = 2.4 + 0.12 x
0.6 = 0.02 x
x = 30
It’s 42.5 like the other girl sayied
Answer:
<u>3 batches of biscuits.</u>
Step-by-step explanation:
For one batch of biscuits, Mito uses 1/4 cup of flour to coat the countertop and the rolling pin.He also uses 2 1/2 cups of flour for each batch of biscuits he bakes
When he uses 7 3/4 cups of flour
Let the number of batches = x
convert the given data to decimal:
2 1/2 = 2.5 and 1/4 = 0.25 and 7 3/4 = 7.75
So, the equation representing the problem is:
2.5 x + 0.25 = 7.75
Solve for x
2.5x = 7.75 - 0.25 = 7.5
x=7.5/2.5 = 75/25 = 3
<u>So, the number of batches of biscuits = 3 batches.</u>
