apprentice can paint the same bed room in 12 hours. If they worked together‚ how long would it take them to paint the bed room? 7. The sum of the digits of a two-digit number is 11. If we interchange the digits then the new number formed is 45 less than the original. Find the original number. Let x = one’s digit t = ten’s digit x + t = 11 x = 11 – t (equation 1) Original number = t × 10 + x Interchanged number = x × 10 + t Interchanged = Original – 45 x × 10 + t

1. If 5 times the value of a number is increased by 3‚ the result is 28. What is the number? 5x+3=28 5x=25 x=5 The answer is 5 2. If 4 times the reciprocal of a number is 3 more than 5/2 times the reciprocal of that number‚ find the number. 4*(1/x)=(5/2)*(1/x)+3 4/x=(5/2x)+3 (8/2x)=(5/2x)+3 (8/2x)-(5/2x)=3 (3/2x)=3 x=1/2 The answer would be x=1/2 3.
