Answer:
? = 7.
Step-by-step explanation:
The two triangles are similar because of the AA Theorem.
The larger triangle's side that is equal to 9 + 3 corresponds to the smaller triangle's side length of 9, while the larger triangle's 21 + ? side corresponds to the smaller triangle's 21 side. Now, we can set up a proportion!
? + 21 = 7 * 4
? + 21 = 28
? = 28 - 21
? = 7

David biked a total of 158 miles (option C)
Why?
- First exercise:
To solve the problem we need to consider that for each 1/2 cup of cornmeal, we will have 6 corn muffins.
So, calculating we have:
We can see that, if each 1/2 cups can give us 6 corn muffins, 2 cups can give us 24 corn muffins.
Hence, there are 3 cups left.
- Second exercise:
We can solve the problem by multiplying or adding the fractions according to the number of dots assigned to each one.
So, calculating we have:
Hence, we have that David covered a total 158 miles. (Option C)
Have a nice day!
