Write an expression that has three terms, two different variable, and one constant.

The three terms are 2x, 3y and 7. Each term separated by a plus sign.

The term 2x has a coefficient of 2 with variable x

The term 3y has a coefficient of 3 with variable y

The term 7 is constant as there is no variable attached to it.

There are infinitely many ways to answer this problem.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
