Tina solved an equation incorrectly, as shown below:
step 1: 8x = 24
step 2: x = 24 − 8
step 3: x = 16
which statement best explains why step 2 is incorrect in tina's solution?
she did not divide 24 by 8.
she did not add 8 to 24.
she did not multiply 24 by 8.
she did not multiply 24 eight times.

 The correct statement is (A) She did not divide 24 by 8.

Step-by-step explanation:  Given that Tina solved an equation incorrectly, as shown below:

Step 1: 8x = 24

Step 2: x = 24 − 8

Step 3: x = 16.

We are to select the correct statement that best explains the reason behind Step 2 incorrect.

The correct steps of the solution are

Therefore, we see that in step 2, Tina should divide 24 by 8, which she did not do and got the incorrect answer.

Thus, the correct statement is (A). She did not divide 24 by 8.

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
