Clara has 6x - 7 pairs of shoes while Daniel has 2x + 3 pairs of shoes. How many more pairs of shoes does Clara have than Daniel

ale4655 [162]

Step-by-step explanation:

This is a binomial subtraction problem.

(6x-7)-(2x+3)

Binomial subtraction problems require one to phrase the problem as addition by flipping the signs.

(6x-7)+(-2x-3)

Now we can simplify:

6x-7-2x-3

4x-7-3

4x-10

So the answer is 4x-10 more pairs of shoes than Daniel.

See if that works.

Hope this helps!

The area of a rectangular city park is 25/54 square miles. The length of the park is 5/9 miles what is the width in the miles of

kotykmax [81]

Note that $A=lw$ , where $A$ is the area, $l$ is the length, and $w$ is the width. Substituting our values in, we have:

$\frac{5w}{9} = \frac{25}{54}$

Multiplying by $\frac{9}{5}$ gives:

$w=\frac{5}{6}$

So the width is $\frac{5}{6}$ miles.
