Solve: the quantity 3x minus 15 divided by 2 = 4x

Mathematics
1 answer:
Anon25 [30]3 years ago
5 0

Answer:

x=-3

Step-by-step explanation:

(3x-15)/2 = 4x

Multiply each side by 2

(3x-15)/2 *2= 4x*2

3x-15 = 8x

Subtract 3x from each side

3x-15-3x = 8x-3x

-15 = 5x

Divide each side by 5

-15/5 = 5x/5

-3 =x

In the accompanying diagram, line BD bisects acute angle ABC and line AD is parallel to line BC. What kind of triangle must tria
galina1969 [7]

Answer:

  isosceles

Step-by-step explanation:

With AD║BC, ∠ADB ≅∠DBC. The angle bisection also ensures that ∠ABD≅∠DBC. Hence the two angles ABD and ADB must be congruent to each other.

A triangle with two congruent internal angles is an isosceles triangle.

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.

Solve:<br> 3x - 4+2(x-5)= 9x + 8- 2x
Zepler [3.9K]

Answer:

x = -11

Step-by-step explanation:

3x - 4 + 2(x - 5) = 9x + 8 - 2x

3x - 4 + 2x - 10 = 9x + 8 - 2x

3x + 2x - 9x + 2x = 8 + 10 + 4

- 2x = 22

- x = 22/2

- x = 11

x = - 11

HEY U OVER THERE! WANT SOME POINTS ANSWER THIS FOR 35!!!!!!
Anuta_ua [19.1K]

Answer:

44

Step-by-step explanation:

x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 294
Combine all like terms for x and integers
6x + 30 = 294

Minus 30 on both sides
6x = 264
Divide by 6
x = 44
