PLZ SOMEBODY HELP ME! THIS IS A REALLY HARD QUESTION! Madison represented the sentence “The product of 3 and the difference of N
egative 4 and the quotient of a number and Negative 2 is at most 5” by using the inequality 3 (Negative 4 minus StartFraction n over negative 2 EndFraction) less-than 5. Which best describes Madison’s error?
“The difference of –4 and the quotient of a number and –2” should be written as StartFraction negative 4 minus n over negative 2 EndFraction.
“The product of 3 and the difference of –4 and the quotient of a number and –2” should be written as 3 (negative 4) minus (StartFraction n over negative 2 EndFraction).
The less than symbol should be replaced with the less than or equal to symbol.
The less than symbol should be replaced with the greater than symbol.
X miles per hour - <span> speed of the boat in still water (x - 2) - speed up the river (x + 2) - speed down the river </span> = 30 * (x + 2) = 38 * (x - 2) 30x + 60 = 38x - 76 - 8x = - 136 x = 17 miles per hour - <span>the speed of the boat in still water.</span>
