170? I think. I don't really understand your question
Answer: 1 27
2. 54
9 243
10. 270
Step-by-step explanation: for one batch, the total minutes will be 15 + 12, so 27. Multiply 27 times b, the number of batches.
There may be another solution IF he is starting to prepare the next batch while the preceding is in the oven. Since this is not stated, I won't offer that solution here.
A’= (10,1)
B’= (8,1)
C’= (9,5)
D’= (7,5)
hope this helps!
Do you simplify it or multiply it?
A square has 4 sides of equal lenght
so if one side is 30 then the other sides are also 30
