Answer:

=6\frac{1}{4}

Step-by-step explanation:

4\frac{1}{4}-\frac{5}{7}+\left(-\frac{2}{7}\right)-\left(-3\right)

4\frac{1}{4}=\frac{4\cdot 4+1}{4}

=\frac{17}{4}

=\frac{17}{4}-\frac{5}{7}+\left(-\frac{2}{7}\right)-\left(-3\right)

=\frac{99}{28}+\left(-\frac{2}{7}\right)-\left(-3\right)

=\frac{99}{28}-\frac{2}{7}-\left(-3\right)

=\frac{13}{4}-\left(-3\right)

=\frac{13}{4}+3

=\frac{25}{4}

\frac{25}{4}=6\frac{1}{4}

=6\frac{1}{4}

On a map, 1cm represents 65 km. If two cities are 1950 km apart, how many centimeters apart would they be on this map?
kakasveta [241]

Answer:

30 cm.

Step-by-step explanation:

We can solve this problem by making a proportion:

1 cm/65 km = x cm/1,950 km

By cross-multiplying, we can solve for x:

65x = 1,950

x = 30
