Jonathan collects postcards and stamps. The number of postcards in his collection is 12 more than 3/4 the number of stamps. He h
zimovet [89]

For this case we define the following variable:

  • <em>x: number of stamps </em>

We now write the equation that models the problem:

\frac {3} {4} x + 12 = 39

From here, we clear the value of x.

We have then:

\frac {3} {4} x = 39-12\\\frac {3} {4} x = 27\\x = (\frac {4} {3}) (27)\\x = (4) (9)\\x = 36

Answer:

The number of stamps he has is:

x = 36

AnnZ [28]

Answer:

Option(D)

Step-by-step explanation:

Diameter of the Sun (S) = 1.4 × 10⁶ km

Diameter of a planet mars (M) = 7000 km

                                            ≈ 7.0 × 10³ km

Ratio of the diameter of the Sun to the diameter of Mars

= \frac{S}{M}

= \frac{1.4\times 10^{6}}{7.0\times 10^{3}}

= 0.2\times 10^{6-3}

= 0.2\times 10^3

= 2\times 10^2

Option (D) will be the correct option.

 King = 4/52 reduces to 1/13

Queen = 4/52 reduces to 1/13
