10. Every car in the USA is fitted with a mileometer. The mileometer shows the total distance that a car has travelled.

Evan is a salesman.

This is the reading on his mileometer at the start of one week. 1 2 5 4 6 5 miles

This is the reading on his mileometer at the end of the week. 1 2 6 3 3 5 miles

a) How many kilometres has Evan travelled in this week?

b) Evan is paid 20 cents for each kilometre he travels. This is to pay for the petrol he uses.

Work out the amount Evan is paid this week for the petrol he uses. Give your answer to the nearest dollar.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
