The answer would be 28 because u count 7 4 times
Answer:
yoy didnt put a picture of the answer choices, so I'm not sure which one this would be, but the answer would be C=5 + .72P
Step-by-step explanation:
C is the total cost, so that would be on the opposite side of the equal sign from P. the 5 would be the constant, since that is the starting price for all packages, and the .72 is the price per pound, so you would have to multiply .72 by P pounds in order to complete the equation.
Hope this helps!
Answer:
Step-by-step explanation:
Consider the quadratic equation, we have
Dividing the equation by a, we get
Put 
on the other side,
Add 
on both the sides,
completing the square, we have
Now, solving for x,
Multiply right side by 
,
which is the required quadratic formula.
Answer:
x + y + z = 180 (this is the first equation)
w + z = 180 (this is the second equation)
Now, rewrite the second equation as z = 180 - w and substitute that for z in the first equation:
x + y + (180 - w) = 180
x + y - w = 0
x + y = w
Step-by-step explanation:
I’m pretty sure it’s B. -3/8x - 1/4 :).
