If the boy grows another 5 inches, he will be 1/2 as tall as his sister. HIs sister is 68 inch tall
Let sister = g, and boy = b
2b + 5 = g
g = 68
Plug in 68 for g
2b + 5 = 68
Isolate the b. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
first, subtract 5 from both sdies
2b + 5 (-5) = 68 (-5)
2b = 68 - 5
2b = 63
Isolate the b. Divide 2 from both sides
2b/2 = 63/2
b = 63/2
b = 31.5
The boy is 31.5 inches tall

Answer:
(2x-1)/2x
Step-by-step explanation:
Given the function 1-(1/x÷2)
Using the rule of BODMAS
Solving the equation in bracket first, will give;
1/x÷2
= 1/x×1/2
= 1/2x
The equation then becomes
1-1/2x
Next is to look for the LCM of the resulting equation
1-1/2x
= (2x-1)/2x
The expression equivalent to the fraction is (2x-1)/2x
