Answer:
Final answer: a-2b+3c
Step-by-step explanation:
5ab/5b= a
-10b^2/5b= -2b
15bc/5b= 3c
F(6) means f times 6 so f6
Answer:
The question has a mistake
Step-by-step explanation:
11d+7c= 172.5
10d+7c= 155.8
By subtraction;
1d+ 0c = 16.7
1d = 16.7
11×16.7+7c=172.5
7c = 172.5-11*16.7
You will get a negative answer yet the cost cannot be negative.
Answer:
The child can sell 15 cookies and 30 lemonade glasses, or 10 cookies and 40 glasses of lemonade, etc

Answer:
∠B and ∠F
∠F and ∠E . . . already listed in the problem statement, so may not be considered an "other pair"
Step-by-step explanation:
∠C and ∠F are vertical angles, so are congruent. Then any angle complementary to one of those will also be complementary to the other.
Likewise, ∠B and ∠E are vertical angles and congruent. Any angle complementary to one of them will also be complementary to the other. Here, ∠E and ∠F are listed as complementary, so we know ∠B and ∠F will be also.
