Jabari owns 100 shares of Stock A and 45 shares of Stock B For the past month, his stocks have been fluctuating inversely. Stock A decreased by m cents per
share and Stock B increased by n cents per share. Which equation can be used to find the total change in value of Jabari's
shares per month?

Answer is

(100*-m)+(45*n)

Step-by-step explanation: because stock  decreases per sock so you're going to multiply 100 times -m because it is decreasing so it will be negative

Then it will be 45*n because it increases per number of stocks so you multiply 45 which is the number of stocks times n

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".
