Ava said she wrote an expression with three terms. She said the first term ha the coefficient 7, the second term have the coefficient 1, and the third has the coefficient 0.1. Each term involves a different variable. Write an expression that could be the expression ava wrote.

7*x + y + 0.1*z

Step-by-step explanation:

An expression that satisfy what Ava said she wrote is the following:

7*x + y + 0.1*z

because

it has 3 terms (each summand); the coefficient (the number that multiplies the variable) of the first term is 7, of the second term is 1 (it is omitted because 1*y = y) and of the third term is 0.1; each term involves a different variable: x, y and z.

The expression can be written as

7a + b + 0.1c

Step-by-step explanation:

Ava wrote an expression with three terms. According to the question each term involve a different variable. This means the term have different value. Since the term have different variable, each term can be represented as follow:

a, b and c

The first term which is a has a coefficient of 7. The second term which is b has a coefficient of 1 and the last term which is c has a coefficient of 0.1.

The coefficient of any value is usually the number in front of it.

The three terms and their coefficients can be expressed as follows:

First term and coefficient = 7a

Second term and coefficient = 1b

Third term and coefficient = 0.1c

The expression Ava wrote can be represented as follows

7a + b + 0.1c

Note an expression that contains variable, symbols (+, - ) and numbers is known as an algebraic expression. And

7a + b + 0.1c is an algebraic expression.
