Answer:
Simplifies to 4k - 32
Explanation:
To solve, translate the word problem into an equation:
"A number K" - k
"decreased by eight" - subtract 8 or k - 8
"the result is multiplied by eight" - multiply 8(k - 8)
"this product is then divided by two" - divide by 2 or 8(k - 8)/2.
8(k - 8) / 2 = 4(k - 8) = 4k - 32.
The simplified form is 4k - 32. To find a final numerical result, substitute any number for k and apply the equation.
