Answer:
its 99
Step-by-step explanation:
because it is the middle of your set after you arrange them in order from least to greatest
You could just put 0 for a and b.
It would work.
Sn = n/2 (a1+an)
= 8/2 (3-38)
= 4 (-35)
= -140
Let x = cost of one cheese pizza.
Let y = cost of one pepperoni pizza.
Set up a system of equations.
6x + 7y = 153.50
2x + 2y = 47.00.
Multiply the second equation by -3
6x + 7y = 153.50
-6x - 6y = -141.00.
Add the equations together
y = $12.00.
Plug 12 into one of our original equations.
2x + 2(12) = 47.
Simplify the left side.
2x + 24 = 47.
Subtract 24 from each side.
2x = 23.
Divide each side by 2
x = $11.50
In conclusion, one pepperoni pizza costs $12.00
Answer:
in this question use the triangle property
A+B+C=180
than you will get the value of x
