Points A, B, and C are collinear. Point B is between A and C. BC=8x+709. AB=487+5x. AC=91. Find BC.
Zolol [24]

Answer:

<h3>            BC = 29</h3>

Step-by-step explanation:

Point B is between A and C and the points A, B, and C are collinear so:

AB + BC = AC

487 + 5x + 8x + 709 = 91

  13x + 1196 = 91

       - 1196      - 1196

   13x  =  - 1105

     ÷13     ÷13

    x = - 85

BC =  8x + 709 = 8(-85) + 709 = - 680 + 709 = 29

Students in Ms. Bell’s geometry class created posters of geometric definitions. Which of the following is the most precise defin
ohaa [14]

Answer:

C

Step-by-step explanation:

D is missing 2 ideas.

  • An angle can be formed by a mixture of the types of figures quoted.
  • An angle has common or shared endpoint.

B: to me is unclear. A line does not have an endpoint. A ray does.

A: you need to mention that the lines are coplanar.

I think, brief though it is, C is the most complete and at the same time simplest choice.

In​ 2006, the population of the country was 30.4 million. This represented an increase in population of 7.6 % since 2001. What w
Molodets [167]

Answer:

28.25 million

Step-by-step explanation:

Population of the country:

  • in 2001 - x million
  • in 2006 - 30.4 million

Population of the country as percent:

  • in 2001 - 100%
  • in 2006 - 100% + 7.6% = 107.6%

Write a proportion:

\dfrac{x}{30.4}=\dfrac{100}{107.6}

Cross multiply:

107.6\cdot x=30.4\cdot 100

Divide by 107.6:

x=\dfrac{30.4\cdot 100}{107.6}=\dfrac{3,040}{107.6}\approx 28.25
