What temperature is 22.7 degrees colder than 96.5 degrees?

22.7 degree  is 73.8 colder than 96.5 degrees

Step-by-step explanation:

22.7 degrees colder than 96.5 degrees, find the temperature

To find the colder temperature we subtract the lowest degree from highest degree .

22.7 degrees colder than 96.5 degrees

So 22.7 degree  is 73.8 colder than 96.5 degrees

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".
