A DVD store charges $4.70 for each day, d, a DVD is rented. The store also gives you a dollar off if the DVD is returned before 5 days. a. Write a rule to represent the rental charges C.
b. How much will you pay if you return the DVD after 4 days? 7 days?

A. C = 4.70d; $18.80, $32.90
B. if d ≤ 5 then C = 4.70d, if d > 5 then C = 4.70d + 1; $17.80, $31.90
C. if d ≥ 5 then C = 4.70d, if d < 5 then C = 4.70d – 1; $17.80, $32.90
D. if d ≤ 5 then C = 4.70d, if d > 5 then C = 4.70d – 1; $18.80, $31.90

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

if farmer matt works for 8 hours a day, how many days will it take him to completely plant 12 rows of crops? each batch of cookies needs 3/4 cups of sugar.

step-by-step explanation:

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun

the answer to this is 4340
