We know that coefficient of an equation is the number multiplied by variable.

-8 and 1.5 are the constants for our given equation.

The variable of our given equation is x. We can also see that x is being multiplied by 0.5, therefore, 0.5 would be the decimal coefficient of our given equation.

In the figure below, the segment is parallel to one side of the triangle. Find the value of x.

g100num [7]

Answer: x= . $18\frac{2}{3}$ .

Step-by-step explanation: We are given a segment parallel to the base.

Therefore, sides of big triangle and small triangles would be in proportion.

$\frac{One \ Side \ of\ big \ triangle }{One \ Side \ of\ small \ triangle} =\frac{Other \ Side \ of\ big \ triangle }{Other \ Side \ of\ small \ triangle}$

Setting values for the shown triangle, we get

$\frac{x+(x+7)}{x} =\frac{16+22}{22}$

$\frac{2x+7}{x} =\frac{38}{16}$

On cross multiplication, we get

16(2x+7) = 38(x)

32x + 112 = 38x.

Subtracting 112 from both sides, we get

32x + 112-112 = 38x -112

32x = 38x-112

Subtracting 38x from both sides, we get

32x-38x = 38x-38x-112

-6x = -112

Dividing both sides by -6, we get

$\frac{-6x}{-6} =\frac{-112}{-6}$

x= . $18\frac{2}{3}$ .

<h3>Therefore, x= . $18\frac{2}{3}$ .</h3>
