Answer:
w = 63; x = 86; y = 38; z = 25
Step-by-step explanation:
Find w:
117 + w = 180 (linear pair)
w = 63
Find x:
x + w + 31 = 180 (sum of measures of interior angles of triangle is 180)
x + 63 + 31 = 180
x = 86
Find y:
x + y + 56 = 180 (sum of measures of three angles equals 180 deg)
86 + y + 56 = 180
y = 38
Find z:
y + z + 117 = 180 (sum of measures of interior angles of triangle is 180)
38 + z + 117 = 180
z = 25
Ceiling = 5 x 4 = 20 m²
The 4 walls = ( 5 + 5 + 4 + 4) x 3 = 18 x 3 = 54 m²
Total area = 20 + 54 = 74 m²
1 m² = $7.50
74 m² = $7.50 x 74 = $555.
Answer: It will cost $444 to white-wash the walls and the ceiling.
Answer:
When A and B are not both zero, the graph of Ax + By = C is always a line. The graph of Ax + By = C, where A and B are not both zero, is a line. Divide both sides by B. Because the form Ax + By = C can describe any line, it is called the standard form of an equation for a line.
