Answer:
1 . An open sentence of the form Ax + By + C < 0 is a linear inequality.
2 . An equation containing more than one variable is a literal equation.
3 . A statement formed by two or more inequalities is a compound inequality.
Step-by-step explanation:
A linear Inequality contains one inequality sign (> or <) sign, In Ax + By + C < 0, Ax + By + C is less than 0.
A literal equation contains more than one variable and equates to a number. An example is Ax + By = 0.
A compound inequality uses OR and AND to join two linear inequalities. When AND is used, it indicates that the values of the variables are true in both inequalities.
X=first number
2x= second side
3.5x= third side
X+2x+3.5x=65
6.5 x= 65
Divide both sides by 6.5
X=10. First side
2x= 20. Second side
3.5x= 35 = third side
10, 20, 35
10*3=30. Next, you add 30+3 which gives you 33. Then divide 33/10 which will give you 3.3. Move the decimal place to the left.
