You can use a proportion.

2/3 inch is to 1 hour as 6 2/3 inch is to x hours.

\dfrac{\frac{2}{3}~inch}{1~hour} = \dfrac{6 \frac{2}{3}~inch}{x}

Cross multiply to get

\dfrac{2}{3} x = 6 \dfrac{2}{3}

\dfrac{2}{3} x = \dfrac{20}{3}

2x = 20

x = 10

Answer: It rained for 10 hours.

fomenos

Choose the point-slope form of the equation below that
PilotLPTM [1.2K]

Answer:

A) y-4=-1/2(x+6)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(0-4)/(2-(-6))

m=-4/(2+6)

m=-4/8

simplify

m=-1/2

y-y1=m(x-x1)

y-4=-1/2(x-(-6))

y-4=-1/2(x+6)
