The total height of three people is 14 ft. Person A is 1 ft taller than Person B. Person C is 2 feet shorter than Person B. How tall is person A?

A. 6ft
B. 3ft
C. 5ft
D. 4ft​

Respuesta :

Step-by-step explanation:

A+B+C = 14

B+1 +B + B-2 = 14

3B -1 = 14

3B = 14+1

3B =15

B = 5

Therefore, A = 5+1 = 6 ft (option A)

14 = A + B + C

14 = (B + 1) + B + (B - 2)

14 = 3b - 1

14 + 1 = 3b

15 = 3b

b = 15 ÷ 3

b = 5

.

A = B + 1

A = 5 + 1

A = 6 (A.)
