Answer:
Lizzy's recipe is not a proportional relationship with the brownie recipe because of the difference in ratio.
Step-by-step explanation:
Brownie recipe:
Cocoa powder = 3 parts
Flour = 2 parts
Ratio of cocoa powder to flour = 3 : 2
Lizzy's recipe:
Cocoa powder = 1 cup
Flour = 1 cup
Ratio of cocoa powder to flour = 1 : 1
Answer:
5(2a -5 + b)
Step-by-step explanation:
(10a - 25 + 5b) = 5( 2a - 5 + b)
5(b + 2a - 5) = 5(2a - 5 + b)
First, set up a proportion. 10.3% is the percentage of students who cancelled, but the question is asking for the students who are attending, so let’s use 89.7% to make it easier. The proportion would be x over 58 is equal to 89.7% over 100%. Multiply 58 by 89.7, giving you 5,202.6. Next, take 5,202.6 and divide it by 100. This should give you 52. 026, but it’s best to round this to 52. 52 students actually attend the art class, making this your final answer.
