The perimeter of the triangular park on the right is 16x-6. What is the missing length? The bottom side length is 5x+4 and the r
Romashka-Z-Leto [24]

Answer:

(9x-5)\ units

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The perimeter of a triangle is the sum of the length of their three  sides

so

P=a+b+c

where

a,b,c are the length sides of the triangle

In this problem we have

P=(16x-6)\ units\\a=(2x-5)\ units\\b=(5x+4)\ units

substitute and solve for the missing length

(16x-6)=(2x-5)+(5x+4)+c\\c=(16x-6)-(2x-5)-(5x+4)\\c=(9x-5)\ units

Inga [223]

Step-by-step explanation:

onvert 3/4 to a percent. Begin by converting the fraction 3/4 into decimal. Multiply the decimal by 100 and write the result with the percentage sign: 0.75 × 100 = 75%.

6 out of 8 can be written as 6/8 and equals to 75%. Let's understand the conversion of a fraction to a percentage. To find the percent for this fraction, we have to find the number of parts that would be shaded out of 100. To convert a fraction to percent, we multiply it by 100/100.
