Answer:

y=10

4 SX +20 Y= 822

Elimination

X - 10 -4

UX - 822-20Y

6.5

10 -4 = 822-201

- 4.5 = 822 - 204

15.54=774

4 = 90:13

= -40.129

Chef Rita is cooking for a Sunday brunch. She knows that 22 pancakes can feed 8 people. She is wondering how many people left pa

defon

Chef Rita can feed 20 people.

Explanation:
If 22 pancakes can feed 8 people, then 11 pancakes can feed 4 people (divide both by 2). Since 55 is 11x5, you multiply 4 times 5 to get 20.

Answer:

M = 7x² +21

Step-by-step explanation:

Subtract the unwanted terms on the left from both sides.

(-7x² +6x -16) + M = 6x +5

M = 6x +5 -(-7x² +6x -16)

M = 7x² +21 . . . . simplify
