Me type the correct answer in each box. 4(px+1)=64 the value of x in terms of p is the value of x when p is −5 is

x =

x(p is - 5) = -3

Step-by-step explanation:

In order to solve for 'x' in the equation, we need to use inverse operations.  We use opposite operations to get rid of the terms connected to the variable and whatever we do to one side of the equation, we do to the other.  First, divide both sides by 4:

px +1 = 16, now subtract '1' from both sides: px +1 - 1 = 16 - 1

px = 15, now divide both sides by 'p':

When p = -5, then we can find the value of x:  

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".
