Elena-2011 [213]
You can set this up as 2 fractions equal to each other, like ratios.

18/11=108/x

Cross multiply and you get 18x=1,188

Now divide both sides by 18 and get x.

x=66.

If the height of the building is 108ft, the width is 66ft.

The product of three consecutive numbers is 990. What is the sum you f the 3 whole numbers?
Amanda [17]

Answer:

20

Step-by-step explanation:

If the three numbers are x, x+1, and x+2, then:

x (x+1) (x+2) = 990

x (x² + 3x + 2) = 990

x³ + 3x² + 2x - 990 = 0

(x - 9) (x² + 12x + 110) = 0

Since x must be a whole number, x = 9.  You can also use simple trial and error to find that the three numbers are 9, 10, 11.

The sum is:

9 + 10 + 11 = 20

Answer:

Adult tickets=275

Step-by-step explanation:

form 2 equations from the given info.

x+y=611

y=x+61

x being the adults and y being the students tickets

then substitute the y equation into the first equation.

x+x+61=611

2x+61=611

2x=550

x=275

and you can check by putting 275 back into the original equations :)
