Yes they are congruent.
Exactly equal in size and shape. Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent.
7+d=19 is the answer
subtract 7 from each side d=19-7
d=12
Answer:

x+5=
11+5= 16
OK. What are the known facts? We need 20 servings, and 1/3 cup is for 8. Let's move things around. Think as if 1/3 was for 5 people. That would mean you would need 1 1/3 cups for 20 servings. Because 5*4 is 20 and 1/3*4 is 1 1/3. Now for the extra 3. There are 4 sets of 3 total left, which is 12. 12 is 1 1/2 of 8, so we need 1/3 cup and half of 1/3. I don't want to give the entire thing away, so I will leave that for you to figure out! Bye :D
