Lorrie biked d miles in 2 hours. She traveled at an average speed of more than 8 miles per hour. To determine the distance she may have traveled, she uses the inequality 2d > 8. She then determines that she biked at most 4 miles. Analyze Lorrie’s inequality and solution.

Step-by-step explanation:

Step 1: Define the problem

Given:

Lorrie biked miles in time hours.

Lorrie traveled at speed which is greater than (mile/hour).

Task:

Lorrie wants to determine the distance she may have traveled.

Key point:

The relation among the distance biked , time , and the speed is represented:

x

Step 2: Substitute given data into the main relation

with: and

=>     x

=>     > x

Simplify:

Step 3: Verify Lorrie's inequality

Lorrie uses the inequality to conclude that she traveled a distance at most miles, or .

Considering the correct answer is at step 2, in which, .

=> Lorrie's conclusion is incorrect.

Hope this helps!

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
