Multiply both sides by (x-2)(x+1) to clea fractions
x(x+1)+(x-1)(x-2)=(-1)(x-2)(x+1)
distribute
x^2+x+x^2-3x+2=-x^2+x-2
add like terms
2x^2-2x+2=-x^2+x+2
add x^2 to both sdes
3x^2-2x+2=x+2
minus x from both sides
3x^2-3x+2=2
minus 2 both sides
3x^2-3x=0
factor
(3x)(x-1)=0
set to zero

3x=0
x=0

x-1=0
x=1

<span>x=0 or 1</span>

Answer:

67°F

Step-by-step explanation:

The mean is another way to say average.

To find the average: you have to add up all of the temperatures, then divide by how many numbers (in this case, time slots) are there.

58°F + 60°F + 61°F + 67°F + 69°F + 73°F + 74°F + 74°F = 536°F

536°F ÷ 8 (total number of time slots) = 67°F
