borishaifa [10]

Step-by-step explanation:

w(2w - 30) = 5400

2w²- 30w = 5400

2w² - 30w - 5400 = 0

(w - 60 ) ( w + 45 ) = 0

w= 60 w= - 45

only take the positive value

therefore w = 60

The ratio of x to y is 1/2 . If the ratio of x + 2 to y + 1 is 2/3 , then what is the value of x?​
Natali5045456 [20]

Answer:

x =4

Step-by-step explanation:

x/y = 1/2

(x + 2) / (y + 1) = 2/3

Cross multiply the first equation

2x = y

Put that value for y into the second equation.

(x + 2) / (2x + 1) = 2/3              Cross multiply

3(x + 2) = 2(2x + 1)                   Remove the brackets.

3x + 6 = 4x + 2                        Subtract 3x from both sides

6 = 4x - 3x + 2

6 = x + 2                                  Subtract 2 from both sides

6-2 = x

x = 4
