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.

Find the probability of drawing a king from a standard deck of cards and then drawing a queen after the first card is replaced i

Arlecino [84]

52 cards in a deck

4 kings

4 queens

King = 4/52 reduces to 1/13

Queen = 4/52 reduces to 1/13

1/13 *1/13 = 1/169

so none of the above
