Answer:
7over9 or -7over9
Step-by-step explanation:
81x power 2 - 8 = 41
(left side) (right side)
first we let the 8 from left side go to the right side,so it will be +8:
81x power 2 = 41+ 8
=49
so now we let the 81 from left side go to right side, so it will be ÷81:
x power 2= 49 over 81
and now we let the power 2 (square) go to the other side so it will become square root:
x = + - √49 over 81
at the end, you will get 2 answers which is 7 over 9 and - 7 over 9

Answer:
Step-by-step explanation:
Six times a number is decreased by fourteen, the result is 124.
Write an equation that represents this
(6 * x) - 14 = 124
Multiply 6 by x to remove the parenthesis
6x - 14 = 124
Add 14 to both sides of the equation
6x = 138
Divide both sides of the equation by 6
x = 23
The unknown number is

Answer:
5 + 2
Step-by-step explanation:
We have to rewrite the given statement in addition form.
The integers have property of:
Negative(-) Negative(-) = Positive(+)
Positive(+) Positive(+) = Positive(+)
Positive(+) Negative(-) = Negative(-)
Negative(-) Positive(+) = Negative(-)
The given statement is:
5-(-2)
Since we have two negative together, it is converted into a positive.
Thus, the given statement can be written in positive form as
5 + 2
