Solve 3[-x + (2 x + 1)] = x - 1.<br> x = 2

Gekata [30.6K]

Answer:

x = -2

Step-by-step explanation:

$3[- x + (2x + 1)] = x - 1$

$= > 3[ - x + 2x + 1 ] = x - 1$

$= > 3[x + 1] = x - 1$

$= > 3x + 3 = x - 1$

$= > 3x - x = - 1 - 3$

$= > 2x = - 4$

$= > x = \frac{ - 4}{2} = - 2$

17. The radius of a circular path is 7m. Find the cost of fencing the path if the cost per meter is Rs.35

Elis [28]

The cost of fencing the path is Rs 1539.38.

It is required to find the cost of fencing the path.

<h3>What is circle?</h3>

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

Given that:

radius of a circular path is 7m.

Rate = Rs .35 per meter

We know that

Circumference of circle = $2\pi r$

$2*\pi *7\\\\=43.98 m$

Circumference of circle=43.98 m

Now,

Cost = Circumference × Rate

Cost =43.98× 35

Cost = Rs 1539.38

Therefore, the cost of fencing the path is Rs 1539.38.
