Question

The number of rooms at hotel g is 10 less than twice the number of rooms at hotel h. If the total number of rooms at hotel g and hotel h is 425, what is the number of rooms at hotel g?

Answer 1

Answer:

260

Step-by-step explanation:

Let number of rooms in hotel g be "G"

Let number of rooms in hotel h be "H"

G = 2H - 10

H + G = 425

Then,

H + 2H - 10 = 425

3H - 10 = 425

3H = 425 + 10

3H = 435

H = 135

G = 2H - 10

G = 2x(135) - 10

G = 270 - 10

G = 260.

Answer 2

Answer:

Step-by-step explanation:

Given: 1]. G=2H-10,

2]. H+G=425.

Now, consider

H+G=425

(G value is 2H-10)

H+2H-10=425

3H=425+10

3H=435

H=435/3

H=145.

Therefore,

G=2H-10

(Where H=145)

G=2(145)-10

G=290-10

G=280.....
