Given the equation, 3/(y - 5) = 15/(y + 4) what is the value of y?
pogonyaev

Answer:

y = 29/4

Step-by-step explanation:

It is given that,

3/(y - 5) = 15/(y + 4)

<u>To find the value of y</u>

we have,

3/(y - 5) = 15/(y + 4)

3(y + 4) = 15(y - 5)

(y + 4) = 5(y - 5)     [dividing both sides by 3]

y + 4 = 5y - 25

5y - 25 = y + 4

5y - y = 4 + 25

4y = 29

y = 29/4

Therefore the value of y = 29/4

1. 6x - 29 = 115<br> 2. 3y - 1 = 29<br> 3. 4z - 32 = 36<br><br> find x, y, and z
joja [24]

Answer:

x = 24 , y = 10, z = 17

Step-by-step explanation:

Given

6x - 29 = 115

6x = 115 + 29

6x = 144

x = 144 / 6

x = 24

3y - 1 = 29

3y = 29 + 1

3y = 30

y = 30 / 3

y = 10

4z - 32 = 36

4z = 36 + 32

4z = 68

z = 68 / 4

z = 17

Hope it will help :)

If using the method of completing the square to solve the quadratic equation
zheka24 [161]

Answer: 25

Step-by-step explanation: The number that is added to both sides is the number that is needed to create a perfect square trinomial.

The question is, what is that number?

Well, it comes from a formula. The number that is added to both sides always comes from half the coefficient of the middle term squared.

So half of -10 squared or -5 squared which is 25.

So 25 is added to both sides.

Holds true for one value of xfrom the set (5, 12, 15, 18). Arrange the equations in increasing order of the x-values that
snow_tiger [21]
6x - 15 = 75 (Third Equation)

6x = 90

x = 15 ✅

x + (x - 10) = 26 (Fourth Equation)

x + x - 10 = 26

2x - 10 = 26

2x = 36

x = 18 ✅

5x - 3x = 10 (First equation)

2x = 10

x = 5 ✅

2(2x - 1) = 46 (Second equation)

4x - 2 = 46

4x = 48

x = 12✅
