height:length
1:2
x feet: 5 feet
You know the length and the ratio of the dimensions. From the ratio you know that the length is twice the height. So height = 5/2 = 2.5 ft.
The water pressure is 45 pounds per square inch. The way to
solve this problem is to first divide the distance covered by the diver which
is 99 feet to the distance with corresponding pressure which is 33 feet. Then
multiply what you get with 15 lbs per in^2.

3x + 2y = 7
y = -3x + 11
Solve the system of equation using substitution.
Substitute the y in the first equation by its value presented in the 2nd equation.
3x + 2y = 7
3x + 2(-3x + 11) = 7
3x - 6x + 22 = 7
-3x + 22 = 7
-3x = 7 - 22
-3x = -15
-3x/-3 = -15/-3
x = 5
Substitute x in the 2nd equation by its computed value. x = 5
y = -3x + 11
y = -3(5) + 11
y = -15 + 11
y = -4
x = 5 ; y = -4
Substitute x and y in the 1st equation with its corresponding values
3x + 2y = 7
3(5) + 2(-4) = 7
15 - 8 = 7
7 = 7
