P= 2.5m + 35 (replace p with 115)
115= 2.5m + 35 (subract 35 from each side)
115 - 35 = 2.5m
80 = 2.5m (divide 2.5 from each side)
80/2.5= 2.5m/2.5
32 = m
The price of the materials is $32
To find the midpoint:
x=3-1/2= 1
y=5+7/2= 6
Answer: yes
Step-by-step explanation: [12(1/2)+5(6)] / 3(3) = 36/9 = 4
X=15, all you have to do is multiply
