The total number of points would be equal to 5n.

You would simply multiply 5 by the amount of questions. In this case, we do not know the amount, so we can use the variable n.

Create a question like
vovikov84 [41]

Answer:

x = (+ - ) 9

Step-by-step explanation:

x^2 = 81

u know how u can sometimes cancel something out by doing the opposite.

This is one of those times as well. the opposite of ^2 = square root.

so if we take the square root of both sides, this will cancel out the^2 on the left side.

sqrt (x^2) = sqrt(81)

x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.

Illusion [34]

Answer:

-2(57+8) = 14 + 6x

step 1 -2 x 57 and -2 x 8   =

step 2 -114-16 = 14 + 6x

                +16    +16

step 3 -114 = 30 + 6x

           -30    -30

step 4 -144 = 6x

           -144/6  6/6

            x = -24

-2(5x + 8) = 14 + 6x

step 1 -2 x 5x and -2 x 8 =

          -10x - 16 = 14 + 6x

step 2 -6x                -6x

           -16x -16 = 14

step 3         +16   +16

            -16x = 30

step 4  -16/-16  30/-16

            x= -15/8
