Answer:

<em>Sam has 29 crayons</em>

Step-by-step explanation:

This problem does not really need to set up an equation to solve. We'll give the answer by simple logic deduction and simple calculations.

We know Luca has 13 more crayons than Sam. We can say that Sam has 13 less crayons than Luca.

Now we are told that Luca has 42 crayons. Considering the above relation found for the number of crayons Sam has, we can assure Sam has 42-13=29 crayons.

Conclusion: Sam has 29 crayons

The scale of a map is 1 inch: 250 miles. City A is 378 miles from City B. To the nearest tenth, how far is its distance on the m

juin [17]

This is a proportion question. We can express this as an equation where the answer is x:

$\frac{1}{250}$ = $\frac{x}{378}$

From there, you can just cross-multiply and divide to get:

$\frac{1 * 378}{250}$

A tenth of 250 is 25, so this is roughly $\frac{375}{250}$ or $\frac{17}{10}$ , so it'll be approximately 1.7 inches on the map.
