Answer 1

Answer:

i think it is A = 14 $\frac{5}{12\\}$ kg

Step-by-step explanation:

A = x + $\frac{5}{2\\}$ kg

B = x

C = x + $\frac{21}{2}$ kg

A + B + C = 48 $\frac{3}{4}$

x + $\frac{5}{2\\}$ kg + x kg + x + $\frac{21}{2}$ kg = $\frac{195}{4\\}$ kg

x + $\frac{10}{4\\}$kg + x kg + x + $\frac{42}{4}$ kg = $\frac{195}{4\\}$ kg

3x + $\frac{52}{4}$ kg= $\frac{195}{4\\}$ kg

3x = $\frac{195}{4\\}$ kg - $\frac{52}{4}$ kg

3x = $\frac{143}{4\\}$ kg

x = $\frac{143}{4\\}$ kg ÷ $\frac{3}{1}$

x = $\frac{143}{4\\}$ kg · $\frac{1}{3}$

x = $\frac{143}{12\\}$ kg

A =  $\frac{143}{12\\}$ kg +  $\frac{30}{12\\}$ kg

A = $\frac{173}{12\\}$ kg

A = 14 $\frac{5}{12\\}$ kg
