5 days ago · Rules for expressions with fractions: Fractions - use a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts. Mixed numerals (mixed numbers or fractions) keep one space between the integer and.
2 days ago · Calculation: 3 x 1/5 - fraction calculator. The result is 3/5 = 0.6 = three fifths
2 days ago · Algebra is the branch of mathematics that studies algebraic structures and the operations [a] they use. [2] An algebraic structure is a non-empty set of mathematical objects, such as the integers, together with algebraic operations defined on that set, like addition and multiplication. [3]
2 days ago · Whole numbers are closed under addition because the sum of two whole numbers is always a whole number. Explain how the process of checking polynomial division supports the fact that polynomials are closed under multiplication and addition.
4 days ago · Euler. Fourier. v. t. e. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.
4 days ago · We can then take cube roots of both sides of the equation, where we note (1 5 − 3 𝑥) = 1 5 − 3 𝑥 and √ 2 7 = 3. Hence, 1 5 − 3 𝑥 = 3. We can now solve for 𝑥. We subtract 15 from both sides of the equation to get − 3 𝑥 = − 1 2. Then, we divide through by − 3 to get 𝑥 = 4.
2 days ago · 3 (x - 2) = 22 - x. one. Solve for x. 6 (x - 1) = 9 (x + 2) x = -8. Kate begins solving the equation 2/3 (6x - 3) = 1/2 (6x - 4). Her work is correct and is shown below. When she adds 2 to both sides, the equation 4x = 3x results.
