(X x 6) = (X x 8) -4

Ps. Make sure yoi dont times the (X x 8) by -4 the -4 is by itself.

I personally found it easier thinking if there is a difference of 4 between 6 x X and 8x X then it must be 2x2 as the difference between 6 and 8 is 2. therefore 4 divided by 2 = 2 and 2 x 2 = 4

Therefore x = 2

Answer:

The inequation 6x ≥ 8x - 4 can be used to find the solution.

The solution is x ≤ 2

Step-by-step explanation:

In math, 'at least' represents greater or equal than (which is the inequation simbol ≥)

If x represents the number then six times a number is the multiplication of x by 6, and four less than eight times the number can be written as: 8x -4

6x ≥ 8x - 4

Solving the inequation;

Substracting 6x each side:

0 ≥ 8x - 6x -4

Suming 4 each side

4 ≥ 2x

Dividing by 2 each side

2 ≥ x

2 greater or equal than x is the same as:

x ≤ 2

Solve the equations PLEASEE<br><br> -1=3x-2<br><br> -3x=9<br><br> -10=-5x
Ilia_Sergeevich [38]

Answers are in bold:

-1=3x-2

add 2 to both sides

-1+2=3x-2+2

1=3x

divide both sides by 3

1÷3=3x÷3

1/3=x

-3x=9

divide both sides by -3

-3x÷-3=9÷-3

x=-3

-10=-5x

divide both sides by -5

-10÷-5=-5x÷-5

2=x

I hope this is good enough:

625^x=5<br><br> A-1/4<br> B1/4<br> C-4<br> D4
murzikaleks [220]
Take logs of both sides:-

ln 625^x = ln 5

x * ln 0.625 = ln 5

x = ln 5 / ln 625

x =  0.25 answer

HELP GEOMETRY find x
morpeh [17]
The Power of a Point theorem tells us, if we draw a line from a certain point, no matter which line we choose, the product of the two distances from the point to the line's intersections with the circles will be constant (or, if the line is tangent to the circle, the value will be equal to the square of the distance to the point of tangency).  So,applying the tangent rule to the x-distance intersection and the two-intersection rule to the other, we have x^2 = 2(2+6) = 16, so taking the square root of the equation gives x=4.
