The sum of two numbers is 100; the first number is 12 less than the second number? What equation best represents the following

Let the first number be f.

Let the second number be s.

f = s-12

f+s = 100

Substitute the f in the first equation for the second equation.

s-12+s = 100

2s-12 =100

2s = 112

s = 56

Therefore f = 56-12 = 44

The 2 numbers are 56 and 44.

Ved used three same triangles to draw a shape. assuming that triangles do not overlap, each of them covers same part of a shape.we need to find the fraction of a shape that each triangle covers. in the numerator we will have number of triangles that we consider. in the denominator we will have total number of triangles.each triangle covers one third of a shape.
