Answer quickly: in the following equation, a, b, and c are constants. in other words, a, b, and c should be treated like numbers. x is the variable. solve the equation for x. show each a+bx=c

a+bx=C

-a .  -a

bx=c-a

/b .  /b

X=c-a/b with the c-a as the numerator and b as the denominator

First you need to get numbers one one side and variables on the other.  a - a + bx = c - a bx = c - a x = (c - a)/b

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

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".
