Wouldn’t it be (-2+12)/2 which is 10/2 which is 5. Because that’s how the midpoint formula works you find starting point and end point, you add those two up together and then divide by 2. So the answer for this one is 5.
20.70=3p+3
17.70=3p
$5.90=p
So if you only needed the equation to describe the word problem it is
$20.70=3p+3
If you want to know how much each pizza was it is $5.90; salad $3.00
Answer:
x=2 and y=3.
Step-by-step explanation:
Let the one number be x and the other number be y.
ATQ, 2x=1+y and x+y=5. x=2 and y=3.
Combine 15x and 7x to get 22x. Then combine 10 and -6 to get 4. Subtract 4 from 180 then you get 176. Divide 22x from 176 to get x=8
