A² - ab + 8b + b² - 1

There are 5 terms in the expression. 
a² = 1st term
ab = 2nd term
8b = 3rd term
b² = 4th term
1 = 5th term

Each term is separated by a plus (+) sign or a minus (-) sign.

A term is either a number, a variable, or a number and a variable multiplied together.

a², ab, b² are variables.
8b is a number and a variable multiplied together
1 is a number.

MatroZZZ [7]

The system of inequalities is:

v + h ≤ 8

v < 2

h ≥ 1.5

<h3>Which system of equations represents this situation?</h3>

Let's define the variables:

  • v = number of hours playing video games.
  • h = number of hours spent on homework.

The maximum time that you can spend on both activities is 8 hours, then:

v + h ≤ 8

You want to spend less than 2 hours on video games, so:

v < 2

You want to spend at least, 1.5 hours on homework, so:

h ≥ 1.5

Then the system of inequalities is:

v + h ≤ 8

v < 2

h ≥ 1.5

madam [21]

Answer:

The total for the housewife's purchase should be 60 dollars. So it should be the vender who owes her money. The vender owes her 15 dollars.

Step-by-step explanation:

$5 = 1kg (eddoes) meaning a total of 2kg eddos =$10

$10 = 1kg (chicken) meaning a total of 5kg chicken = $50

When added together, it'd be 60 dollars.
