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.

Cross-multiplying both sides:
1.5 = 5(.2 + x)
=> 1.5 = 1 + 5x
=> 0.5 = 5x
=> x = .5/5
=> x = 0.1

\(\frac{1.5}{0.2+x}=5\)
\(1.5=5(0.2+x)\)
\(1.5=1 + 5x\)
\(1.5-1=5x\)
\(0.5=5x\)
\(x=0.1\)

Answer: B

\(\frac{1.5}{0.2 + x} = 5\)

\(\frac{1.5}{5} = 0.2+x\)

\(x = 0.3-0.2 = 0.1\)

Answer = B

(A) -3.7

(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.
