aliya0001 [1]

Answer:

80 ways

Step-by-step explanation:

In this case, what we should do is that, for every 1 main course there are 8 appetizers, but there are 10 main courses therefore:

Alyssa is building a brick mailbox. She is going to stack bricks that are each \dfrac23 \text{ft}

aalyn [17]

Given that each of the brick is $\frac{2}{3}$ ft tall and the finished stack of bricks is $4\frac{2}{3}$ ft tall.

Let the number of bricks in the stack be x, then

$\frac{2}{3} x=4 \frac{2}{3} = \frac{14}{3} \\ \\ \Rightarrow x= \frac{ \frac{14}{3} }{ \frac{2}{3} } = \frac{14}{3} \times \frac{3}{2} \\ \\ = \frac{14}{2} =7$

Therefore, 7 bricks will go in the stack.
