2) The levels of lead in two bodies of water are rising. In one body of water the initial lead level was 0.04 parts per billion (ppb) and is rising by 0.05 ppb every year. In the second
body of water, the initial lead level was 0.13 ppb and is rising by 0.09 ppb each year.
Which equation can be used to find y, the year in which both bodies of water have the
same amount of lead?
a) 0.04y + 0.05 = 0.13y + 0.09
b) 0.04 + 0.05y = 0.097 + 0.13
c) 0.05 +0.04 = 0.13y + 0.09
d) 0.04 + 0.05y = 0.09 + 0.13

it is x equals 3   plese mark me really need it

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
