Change of subject x the subject y=2x+3/5x-2

Mathematics
1 answer:
Nezavi [6.7K]3 years ago
7 0

Answer:

x = \frac{3+2y}{5y-2}

Step-by-step explanation:

Given

y = \frac{2x+3}{5x-2} ← multiply both sides by (5x - 2)

y(5x - 2) = 2x + 3 ← distribute left side

5xy - 2y = 2x + 3 ( add 2y to both sides )

5xy = 2x + 3 + 2y ( subtract 2x from both sides )

5xy - 2x = 3 + 2y ( factor out x from each term on the left side )

x(5y - 2) = 3 + 2y ← divide both sides by (5y - 2)

x = \frac{3+2y}{5y-2}

Find the exact value of x in the triangle below
Juli2301 [7.4K]

So this is a special triangle. The 30-60-90 triangle rule states that if the short leg is y, then the hypotenuse is 2y and the long leg is y√3.


In this case, the short leg is 5√3 since that times √3 makes 15.


Now with the hypotenuse, just multiply 5√3 with 2, and your answer should be 10√3, or C.

What is the number of diagonals that intersect at a given vertex of a hexagon, heptagon, 30-gon and n-gon?
DENIUS [597]

Answer:

i. 9

ii. 14

iii. 405

iv. \frac{n(n-3)}{2}

Step-by-step explanation:

The number of diagonals in a polygon of n sides can be determined by:

\frac{n(n-3)}{2}

where n is the number of its sides.

i. For a hexagon which has 6 sides,

number of diagonals = \frac{6(6-3)}{2}

                                   = \frac{18}{2}

                                   = 9

The number of diagonals in a hexagon is 9.

ii. For a heptagon which has 7 sides,

number of diagonals = \frac{7(7-3)}{2}

                                   = \frac{28}{2}

                                   = 14

The number of diagonals in a heptagon is 14.

iii. For a 30-gon;

number of diagonals = \frac{30(30-3)}{2}

                                          = \frac{810}{2}

                                         = 405

The number of diagonals in a 30-gon is 405.

iv. For a n-gon,

number of diagonals = \frac{n(n-3)}{2}

The number of diagonals in a n-gon is \frac{n(n-3)}{2}
