Step-by-step explanation:
180-106=74
74/2=37
m<1=37°
m<2=37°
m<3=m<1=37°
m<4=m<2=37°
m<5= 106°
Answer:
a + b + c = P
Step-by-step explanation:
Step-by-step explanation:
the mean value is the sum of all values divided by how many values there are.
so,
(3 + -5 + 70 + -90 + -13) / 5 = -35/5 = -7
-7° F is the mean temperature of the 5 cities.
Answer:
x=1/2, x=-3
Step-by-step explanation:
2x^2+5x-3 = 0
(2x^2+6x)+(-x-3) = 0
2x(x+3)+-1(x+3) = 0
(2x-1)(x+3)=0
2x-1=0, x+3=0
x=1/2, x=-3
