The sum of two numbers is 66 . the smaller number is 12 less than the larger number. what are the numbers

The two numbers are 39 and 27.

Step-by-step explanation:

To find these numbers, set the first number equal to x. Then the second number can be described as x - 12. Using these two terms, you can add them together and set equal to 66.

x + x - 12 = 66

2x - 12 = 66

2x = 78

x = 39

Given this as the first number, put into the second equation to find the next.

x - 12

(39) - 12

27

at least two

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
