An 'equation' is a statement that you're given, and you're told that it's true.
You can add or subtract the same number to each side of the equation, and you
can multiply or divide each side of the equation by the same number, without
changing the truth of the statement. These handy operations are the methods
you use to tease out the value that the equation's variable must have in order
for the statement to be true.
(There's no such thing as the 'value' of an equation, only the truth of the equation,
and the value of its left side, its right side, and its variable.)
Ratio
It means that in an equation, you can multiply both sides (left and right of the equal sign) by the same number (except zero), without changing the result set.
You cannot. A square can be distorted into a rhombus without changing the lengths of any of the sides, but with a different area. Similarly, the shape of any quadrilateral can be altered without affecting the length of its sides but changing its area.
A hexagon has 6 sides. To figure out the total number of sides on 13 hexagons, simply multiply these two numbers together:Total number of sides = 6 x 13 = 78
You can add, subtract, multiply, or divide both sides of the equation or inequality by the same number. Don't multiply or divide by zero. In the case of an inequality, if you multiply or divide by a negative number, the sign of the inequality must be reversed. E.g., if you multiply both sides by -2, a "less-than" sign should be replaced by a "greater-than" sign.
Make sure you do the same thing to both sides of the equation.
It means that in an equation, you can multiply both sides (left and right of the equal sign) by the same number (except zero), without changing the result set.
five
you subtract 3 from the number of sides then multiply that by the number of sides divided by 2
A hexagon has 6 sides, and a pentagon has 5 sides. Thus, if you were to multiply the number of sides of a hexagon with the number of sides of a pentagon, you would get a total number of 30 sides.

you multiply 180 by the number of sides
Suppose the number is x. Then 7x = 2x + 20 Subtract 2x from both sides: 5x = 20 Divide both sides by 5: x = 4
A hexagon has 6 sides. To figure out the total number of sides of four hexagons, simply multiply 6 by 4:Total number of sides = 6(4) = 24
A hexagon has 6 sides. To figure out the total number of sides on 13 hexagons, simply multiply these two numbers together:Total number of sides = 6 x 13 = 78
Leave it alone. You cannot make an inequality into an equality by multiplying both sides of the inequation by the same number. If instead of the inequality sign you are using a lesser or greater than sign, however, you will need to reverse it if you multiply both sides by the same negative number, e.g. 10>4. If you multiply both sides by -2, you need to change the > into a <, so -20<-8
What you do to get your answer is to multiply the number of sides (8) times the number of measurement the sides are measured with (4) so your answer should be 32. hope this worked for you (it should)
Change the direction of the inequality.
