Answer 1

Answer:

75 calories

Step-by-step explanation:

Calories of

Apple = a

Banana = b

Peach = c

According to first statement

a = c + 29

29 = a - c ------(1)

a = b - 13

13 = b - a -------(2)

According to second statement

3a = 2b + 2c - 43

43 = 2b + 2c - 3a

43 = 2(b + c) - 3a ------(3)

Subtract equation (1) from (2)

13 - 29 = b - a - a - (-c)

-16 = b + c - 2a

b + c = 2a - 16

Substitute value of b + c in equation (3)

43 = 2(2a - 16) - 3a

43 = 4a - 32 - 3a

43 = a - 32

a = 43 + 32

a = 75
