-4 (x - 5) + 3 (a - 7)
First, expand your problem. / Your problem should look like: -4x + 20 + 3a - 21
Second, simplify. / Your problem should look like: -4x + 3a - 1
Answer: -4x + 3a - 1 (C)
Sum of all the interior angles = (5-2)x180 = 540°
540 - 100 - 120 - 100 - 90 = 130°
So the last unknown angle in the polygon is 130°
Sum of all the adjacent angles on a straight line is 180°
Angle 1 = 180 - 130 = 50°

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.
Answer:
x = 468%
Step-by-step explanation:
I see a proportion here.
we want to solve for the variable x in the proportion:
18% / (2 weeks) = ( x %) / (52 weeks)
here we should multiply 52 to boths sides
(52 weeks) * 18% / (2 weeks) = x %
26 * 18% = x %
x = 468 %
