Aconsultant traveled 280 miles to attend a meeting, traveling 50 mph hours for the first part of the trip, then increasing to a speed of 65 mph for the second part. if the entire trip took 5 hours, how far did the consultant travel at the faster speed?

step-by-step explanation:

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".

i’m here for points.

the answer is 99.
