Answer:
Angles 5 and angle 2 are supplementary angles
Step-by-step explanation:
Angle 2 and angle 6 are corresponding angles and corresponding angles are equal when we have parallel lines
Angles 5 and angle 6 are supplementary angles since they form a line
Replace angle 6 with angle 2 since they are equal
Answer: 500$
Step-by-step explanation: 150 is 70% off the ORIGINAL price, so 150 is actually 30% off. Divide everything by 3 and you get 50$ = 10%. Multiple 50 by 10 and you get 500, your answer.
Apply to Row 2 : Row 2 + Row 1
2x + 2y + 3z = 0
y + 4z = -3
2x + 3y + 3z = 5
Apply to Row 3: Row 3 - Row 1
y = 5
Apply to Row 3: Row 3 - Row 2
-4z = 8
Simplify rows
z = -2
<em>Note that the matrix is in echelon form now. The next steps are for back substitution.</em>
Apply to Row 2: Row 2 - 4 Row 3
Apply to Row 1: Row 1 - 3 Row 3
2x + 2y = 6
Apply to Row 1: Row 1 - 2 Row 2
2x = -4
z = 2
Simplify the rows
<u>x = -2</u>
<u>y = 5</u>
<u>z = -2</u>
$7,333.33 (approximately)
First step: = 1,000,000,000,000
Second step: 2.2 x 1,000,000,000,000 = 2,200,000,000,000
Third step: 2,200,000,000,000 ÷ 300,000,000 = 7,333.333333333333
