Because your multiping the inverse to both sides
Algebraic inequalities can be solved in the same fashion as algebraic equations. The goal here, as in algebraic equations, is to isolate the variable. The one thing to remember, however, is that when dividing or multiplying both sides by a negative number, one must switch the inequality sign.
Algebra
It means: First, Outers, Inners, Last and is the order of operations when multiplying out bracket in algebra
it means you're multiplying them.
algebra is came from the latin word ca ajlre which means rational, equation, quantity, inequality, and the exponent is one or more.
- is the prefix for negative numbers in algebra.
5(10^(-2)) = 5 / (10^2) = 5/100 = .05 because multiplying any number by a negative exponent (such as 10^(-2)) is the same as dividing by its reciprocal (10^2)
The word "pathers" is not recognised in the context of algebra.
The whole point of using n in algebra is that it stands for an unspecified number. Until you have an equation (or inequality) that involves n and solve it for a value of n.
YEs
t - 3 is an expression: not en equation nor an inequality. therefore, there cannot be an answer.
