Answer:

$4\frac{1}{2}$ feet further.

Step-by-step explanation:

Since these are mixed numbers that are both in fourths, we can easily subtract the two numbers. However, I find it easier if we first convert both mixed numbers into improper fractions.

$5\frac{1}{4} = \frac{5\cdot4+1}{4} = \frac{21}{4}$

$9\frac{3}{4} = \frac{9\cdot4+3}{4} = \frac{39}{4}$

Now we can subtract the numerators:

$\frac{39}{4} - \frac{21}{4} = \frac{39-21}{4} = \frac{18}{4}$

$\frac{18}{4}$ simplifies down to $\frac{9}{2}$ .

Converting $\frac{9}{2}$ to a mixed number is easy - 2 goes into 9 4 times (8) with one remainder so:

$4\frac{1}{2}$ .

Hope this helped!

2 (-n -3) -7 (5 + 2n)

leonid [27]

Answer: -16n-41

Step-by-step explanation:

first, distribute 2 through the parentheses:

2(-n-3)-7(5+2n) = -2n-6-7(5+2n)

second, distribute 7 through the parenthesis:

-2n-6-7(5+2n) = -2n-6-35-14n

Collect like terms:

-2n-6-35 and -16n-6-35

Calculate the difference:

-2n-6-35-14n = -16n-41

SOLUTION:

-16n-41
