Brianna's block has an area of 3/8 square mile of the block is 3/4 of a mile long how wide is the block?

w = 1/2

Step-by-step explanation:

The formula is A = lw

where A is the area, l is the length and

w is the width.

Given that Area of the block is 3/8, length is 3/4, width= ?. Find the width.

3/8 = 3/4 × w

Multiply both sides by 4/3 to get the value of w:

= 3/8 × 4/3 = w

4/8 =w

w = 1/2

I hope this is clear, please mark as brainliest answer.

each side has a different length.  

step-by-step explanation:

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
