The sixth-graders at Barbara's school got to choose between a field trip to a museum and a field trip to a factory. 39 sixth-graders picked the museum and 26 sixth-graders picked the factory. What percentage of the sixth-graders picked the museum

60%

Step-by-step explanation:

Sixth-graders that picked the museum = 39

Sixth-graders that picked the factory = 26

Total number of sixth graders = 39 + 26 = 65

Therefore, the percentage of the sixth-graders that picked the museum would be:

= Sixth-graders that picked the museum / Total number of sixth graders × 100

= 39/65 × 100

= 60%

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
