How many years are in 416 weeks?
1 year = 52 weeks; multiply each side of the equation by 8 and you will see the inequality 8 years = 416 weeks.

How do you multiply centimeters squared by centimeters?
you take a ruler and you measure each side and you multiply each numbers of each side
If you replace the equal sign of equation with inequality sign is there ever a time when the same value will be a solution to both the equation and the inequality?
No. You have written two quantities. They can't be equal to each other AND also UNequal to each other.
How do you solve inequallities?
Solving inequalities is quite similar to solving equalities - you try to isolate the variable on one side. The main difference is that if you multiply (or divide) by a negative number, you have to invert the inequality. Here is an example: -2x + 3 > 11 Subtract 3 from each side: -2x > 8 Divide both sides by (-2) - note that this involves inverting the sign: x < -4 Inverting the inequality can be tricky if you have to multiply or divide by a variable expression. You may have to consider both cases - that the expression is positive, and that it is negative.
How do you put greater than symbol on the calculator?
Unless it's a fancy graphing calculator, you don't. When solving an inequality, you need to solve it as an equality, remaining mindful of the proper direction of the inequality symbol after each step.
How is solving an inequality different from solving an equation?
In solving an inequality you generally use the same methods as for solving an equation. The main difference is that when you multiply or divide each side by a negative, you have to switch the direction of the inequality sign. The solution to an equation is often a single value, but the solution to an inequality is usually an infinite set of numbers, such as x>3.
What do you do when you have a negative variable?
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
How many years are in 416 weeks?
1 year = 52 weeks; multiply each side of the equation by 8 and you will see the inequality 8 years = 416 weeks.
Each number below is a solution of the inequality 2x plus 3 and gt7 EXCEPT?
I don't see any numbers below.One method to solve this is to replace each of the numbers in the inequality, do the calculations, and then check whether the inequality is satisfied. Another method is to get the general solution for the inequality, then check with each of the numbers.
Write an inequality for each sentence Graph the solutions of each inequality on a number line r is not greater than five?
r <= 5.

Can equations and inequalities be solved the same way?
Mostly true.As with equations, you can add or subtract the same amount to each side of an inequality. You can also multiply or divide by any positive number. The only difference is that if you multiply or divide by a negative number then the direction of the inequality needs to be flipped.For example, if 2x < 8 (ie x < 4), then2x - 8 < 8 - 8or (2x)/4 < 8/4but -3*2x > -3*8
When solving inequalities using multiplication explain the difference between multiplying each side of the equation by a positive number and multiplying each side of the equation by a negative number?
When you multiply both sides by a negative number the inequality must be flipped over. You do not do that when multiplying by a positive number.
How do you graph an inequality?
