Ria solves the equation 5 + 3r = 4 + 4r and gets r = r. She concludes that theequation has infinitely many solutions. What is the correct solution? What mistake
did Ria make?

Answers

5+3r=4+4r
subtract 4 from both sides
1+3r=4r
subtract 3r from both sides
1=r

Final answer:

To solve the equation 5 + 3r = 4 + 4r, we need to isolate the 'r' term on one side of the equation. Ria made a mistake by stating that the equation has infinitely many solutions, but the correct solution is r = 1.

Explanation:

The equation given is 5 + 3r = 4 + 4r. To solve this equation, we need to first simplify both sides by combining like terms. On the left side, 5 does not have a 'r' term, so we can leave it as it is. On the right side, 4 has a 'r' term, so we can write it as 4r. Now we have 5 + 3r = 4r + 4. To solve for 'r', we need to isolate the 'r' term on one side of the equation. We can do this by subtracting 3r from both sides of the equation. This gives us 5 = 4r + 4 - 3r. Simplifying further, we get 5 = r + 4. Now, to isolate 'r', we can subtract 4 from both sides of the equation. This gives us 1 = r. Therefore, the solution to the equation is r = 1.

Solve the formula A=lw for l

Answers

The solution for l in terms of A and w is: l = A / w. To solve the formula A = lw for l (length), we need to isolate the variable l on one side of the equation.

Follow these steps:

Step 1: Start with the formula: A = lw

Step 2: Divide both sides of the equation by w to isolate l:

A / w = lw / w

Step 3: Simplify the right side of the equation:

A / w = l * (w / w)

Step 4: Since w / w equals 1, we have:

A / w = l * 1

Step 5: Therefore, l is equal to:

l = A / w

So, the solution for l in terms of A and w is:

l = A / w

Jay traveled from Miami to Jacksonville, a distance of 320 miles. He left Miami at 8:00am, stopped for lunch for 30 minutes, and stopped for two 15 minute breaks at rest areas. He arrived in Jacksonville at 2:15pm. What was his average rate of speed during his travel time? Please explain the steps to get the answer. Thanks!

Answers

To find the “Average Rate of Speed", we know we need the Total Distance and the Total Time. The Total Distance is 320 miles and the Total Time is 14:15 - 8:00 = 6:15 hours = 6.25 hours .So the Average Rate = 320 miles/ 6.25 hours = 51.20 mph.
