Zarina likes to walk around pelican park the park is square 7/10 mi on each side one morning she walked around the park 3 1/2 times before stopping to rest how far had she walked

9.8 mi

Step-by-step explanation:

Given in question as each side of a square park is

Number of times Zarina walked around the park is 3 times

So, the total distance she travel = 3 (4 ×) + 2 ×

Or, +

Or,

∴

or , = 9.8

Hence  The distance she covered is 9.8 mi   Answer

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
