The answer is true. The image shows an adjacent supplementary angle.
8x+140=180
8x=40
x=5
Answer: provide a picture, that would help
Step-by-step explanation:
In a parallelogram, opposite sides have the same length.
3x + 9 = 5x -5
group like terms on one side
9 + 5 = 5x -3x
14 = 2x
x is 7.
Since AB is 5x -5
AB = 5(7) -5
AB = 30.
BX is half of the line DB. So BX = DX
5y = 7y - 10
10 = 7y -5y
10 = 2y
y =5.
Since BX = 7y - 10
BX = 7(5) -10
BX = 25
Answer:
7.1 x 10³
Step-by-step explanation:
Move your decimal so that it follows your first whole number greater than zero. The number of places you moved the decimal is the same as the exponent. Since the number 7.1 needs to INCREASE to be 7,100, then the exponent is positive.
Answer: If you were to graph the solution it would be evident. One solution is when the lines meet at one point, no solution is when the lines are parallel to each other (they do not touch) and infinitely solutions happens when the two lines are on top of each other.
