solving for x we get x = 0.1

When we divide a number \(D,\) the dividend, by another number \(d,\) the divisor, we obtain the quotient \(Q.\) Obviously, the dividend is the product of the quotient and the divisor: \(D=dQ.\) In our case, \(1.5=5(0.2+x)\) or \(1.5=1+5x,\) from which \(5x=0.5\), and finally, \(x=0.5/5=0.1.\) Answer B.

(A) 3.7 (B) 0.1 (C) 0.3 (D) 0.5 (E) 2.8
Crossmultiplying both sides: 1.5 = 5(.2 + x) => 1.5 = 1 + 5x => 0.5 = 5x => x = .5/5 => x = 0.1 B

\(\frac{1.5}{0.2+x}=5\) \(1.5=5(0.2+x)\) \(1.5=1 + 5x\) \(1.51=5x\) \(0.5=5x\) \(x=0.1\) Answer: B

\(\frac{1.5}{0.2 + x} = 5\) \(\frac{1.5}{5} = 0.2+x\) \(x = 0.30.2 = 0.1\) Answer = B

(A) 3.7 (B) 0.1 (C) 0.3 (D) 0.5 (E) 2.8
Solution: We are given the following equation: 1.5/(0.2+x) = 5 We begin by multiplying both sides of the equation by (0.2 + x), and we obtain: 1.5 = 5(0.2 + x) 1.5 = 1 + 5x 0.5 = 5x 0.5/5 = x 0.1 = x The answer is B.

\(\frac { 1.5 }{ 0.2+x } =5,\quad x=?\\ 1.5=5(0.2+x)\\ 1.5=1+5x\\ 1.51=5x\\ 0.5=5x\\ x=\frac { 0.5 }{ 5 } \\ x=0.1\) OA

1.5/0.2+x =5 => cross mutiply => 1.5 = 1.0+5x =>0.5/5 = x => 0.1
