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

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
