3^x + 3^2 = 90
Simplify the known power:
3^x + 9 = 90
Subtract 9 from both sides:
3^x = 81
Take the cubic root of both sides:
X = 4
Answer:
4 batches
Step-by-step explanation:
1 batch requires 3 cups apples and 1 cup blackberries
1 batch has (3+1) = 4 cups total of apples and blackberries
We use 16 cups of apples and blackberries
16/4 = 4
So we are multiplying by 4
That means 1batch*4 = 4 batches
