Ab = 10x + 4 bc = 4x - 3 ac = 12x + 16 what is x, ab, and bc?

We know that

AB = 10x + 4

BC = 4x - 3

AC = 12x + 16

We need to find x, AB and BC.

The solution of the question is based on the assumption that the point A, B and C are col-linear, i.e. they lie on the same line, and B lies between A and C

⇒ AB + BC = AC

Substituting the values of AB, BC and AC in terms of x in the above equation, and solving the linear equation.

⇒ 10x+4 + 4x-3 = 12x+16

⇒ 14x+1 = 12x+16

⇒ 2x = 15

⇒ x = 7.5

Substituting the value of x in 10x+4 to determine the length of AB

AB = 10x+4

⇒ AB = (10×7.5)+4

⇒ AB = 75+4

⇒ AB = 79

Hence, AB is 79 units

Substituting the value of x in 4x-3 to determine the length of BC

BC = 4x-3

⇒ BC = (4×7.5)-3

⇒ BC = 30-3

⇒ BC = 27

Hence, BC is 27 units

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
