Question

На отрезке АВ отметили точку С , так что СВ равна = 7 1/4 м. , а СВ на 2 1/4 м. меньше АС . Найдите длину отрезка АВ

Answer 1

Cb=7 м 25 смс, выясняем, чему равен отрезок АС, 7м 25 + 2 м 25 см = 9 м 50см, складываем величины 7м 25 см + 9 м 50 см = 16 м 75 см или иначе 16 3/4 м

Answer 2

I can answer your question in detail. On the segment AB, point C was marked so that CB equals 7 1/4 m, and CB is 2 1/4 m less than AC. Find the length of the segment AB.

To solve this problem, we need to use the property of segments: the sum of the lengths of two segments is equal to the length of the third segment. In other words, AB = AC + CB.

We are given that CB = 7 1/4 m and CB = AC - 2 1/4 m. We can substitute these values into the equation above and get:

AB = (CB + 2 1/4) + CB AB = (7 1/4 + 2 1/4) + 7 1/4 AB = 9 1/2 + 7 1/4 AB = 16 3/4

Therefore, the length of the segment AB is 16 3/4 m.
