Answer:

see below

Step-by-step explanation:

5.  9x + 2 = 119°                    alternate interior angles are congruent

          9x = 117

           x = 13°

6.  12x - 8 + 104° = 180°       same side interior angles are supplementary

            12x + 96 = 180

                     12x = 84

                        x = 7°

7.  5x + 7 = 8x - 71                alternate exterior angles are congruent

         -3x = -78

            x = 26°

8.  4x - 7 = 7x - 61                corresponding angles are congruent

        -3x = -54

          x = 18°

9.  9x + 25 = 13x - 19          corresponding angles are congruent

            -4x = -44

               x = 11°

    13x - 19 + 17y + 5 = 180°        straight line adds up to 180°

    13(11) - 19 + 17y + 5 = 180

       143 - 19 + 17y + 5 = 180

                    17y + 129 = 180

                              17y = 51

                                  y = 3°

10.  6x - 7 + 3x - 29 = 180°     same side interior angles are supplementary

                   9x - 36 = 180

                           9x = 216

                             x = 24°

     6x - 7 = 8y + 17                   vertical angles are congruent

      6(24) - 7 = 8y + 17

         144 - 7 = 8y + 17

               137 = 8y + 17

               120 = 8y

                  y = 15°

11.  49 + 3x = 7x - 23                corresponding angles are congruent

            -4x = -72

               x = 18°

 

      3x = 11y - 1                         corresponding angles are congruent

      3(18) = 11y - 1      

          54 = 11y - 1

          55 = 11y

            y = 5°

12.  5x - 38 = 3x - 4                alternate interior angles are congruent

             2x = 34

               x = 17°

 

      7y - 20 + 5x - 38 + 90 = 180°        sum of triangle interior angle equals 180

      7y - 20 + 5(17) - 38 + 90 = 180°      

      7y - 20 + 85 - 38 + 90 = 180°    

                              7y + 117 = 180

                                      7y = 63

                                       y = 9°

Answer:

Step-by-step explanation:

or,4x + 40 - 40 (subtract and the answer will be o ; no valueit will get )= 16-40

or, 4x = 16-40

therefore, 4x = 16-40

6th grade math:) please help..

Answers

Answer:

Okay the ratio of starfish to fish is 3:6 or 3/6 but simplified it is 1/2

The starfish ratio to 16 fish would be 8 or 16:8

and if there was one less starfish in the line the ratio would be 2:6 or 2/6 but simplified would be 1/3

Step-by-step explanation:

Okay to solve the first question we see that there are 6 fish and 3 starfish, when put into a ratio it is 3:6 (the reason the number of starfish is first in the ratio is because it is starfish to fish hence starfish goes first ). If you are wanting the ratio to be in fraction form you are going to put 3/6 and since 3 goes into 3 once and 6 twice so the fraction is 1/2

3:6 = 3/6 = 1/2

Since the ratio from starfish to fish is 1/2 of that number you are going to divide 16 by 1/2 or more like multiply:

16/ 1/2 = 16/1 * 1/2 = 16/2 = 8

I hope this helps you!!!

When the ratio of starfish is short of one then the ratio would be 2: 6 or in fraction form 2/6 but simplified is 1/3.

2:6 = 2/6 = 1/3

Vogel.The first complete elevator machine in the United States, constructed in 1855, was a complex and inefficient contrivance built around an oscillating-cylinder steam engine. The advantages of an elevator system independent of the mill drive quickly became apparent, and by 1860 improved steam elevator machines were being produced in some quantity, but almost exclusively for freight service. It is not clear when the first elevator was installed explicitly for passenger service, but it was probably in 1857, when Otis placed one in a store on Broadway at Broome Street in New York.In the decade following the Civil War, tall buildings had just begun to emerge; and, although the skylines of the worlds great cities were still dominated by church spires, there was increasing activity in the development of elevator apparatus adapted to the transportation of people as well as of merchandise. Operators of hotels and stores gradually became aware of the commercial advantages to be gained by elevating their patrons even one or two floors above the ground, by machinery. The steam engine formed the foundation of the early elevator industry, but as building heights increased it was gradually replaced by hydraulic, and ultimately by electrical, systems.According to this excerpt, what was an underlying cause of increased steam elevator production?construction of tall buildingsthe need to move supplies in millsan elevator in a store on Broadwaycommercial advantages The angle measures of a triangle are shown in the diagramwhat is the value of x?pls hurry its due soon what are 2 ratios equivalent to 2:12 Help quickly please...
