The shortest route from London to Birmingham is 120 miles. A lorry is expected to take 2 hours to travel this route.
The lorry actually travels by a different route which increases the distance by 20%, but it still arrives in 2 hours.
By how many more mph than the expected speed does the lorry travel?

Working on itts i’m going to need you to me as i go along 1-5

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
