In the simplified form the expression is x+4
Answer:
21x + 29y - 8
Step-by-step explanation:
(−7x+8x+19y)−(6y+8−20x−16y)
−7x+8x+19y−6y-8+20x+16y
(−7x+8x+20x)+(19y−6y+16y)-8
21x + 29y - 8
12 liters because 2.75 gallons is not greater then 12 liters.
5 weeks -> $20
Divide 5:
1 week -> $4
Replace week with "w" and $ with "s"

The midpoint formula is x1+x2 divided by 2 minus y1+y2divided by 2. You should get your midpoint as a coordinate in the form of (x , y)
