Answer:

-7k

Step-by-step explanation:

(−102+7k+6×4)+(−14−464−14k)

Multiply 6 and 4 to get 24.

−102+7k+24−14−464−14k

Add −102 and 24 to get −78.

−78+7k−14−464−14k

Subtract 14 from −78 to get −92.

−92+7k−464−14k

Subtract 464 from −92 to get −556.

−556+7k−14k

Combine 7k and −14k to get −7k.

−556−7k

The country recreation department cleared a 3/4 mile long walking trail in Washington Park. There will be a small sign every 1/1
dem82 [27]

We are given " The country recreation department cleared a 3/4 mile long walking trail in Washington Park."

Therefore total distance = 3/4 miles.

"There will be a small sign every 1/12 mile along the trail, including at the beginning and end of the trail. "

Distance of small sign = 1/12 mile.

We need to find the number of signs in 3/4 miles each of 1/12 miles.

<em>In order to find the number of signs, we need to divide total distance by distance of a small sign.</em>

3/4  ÷ 1/12

= 3/4 × 12/1 = 3 × 3

= 9 signs.

<h3>Therefore, 9 signs are needed.</h3>
