7. There are 25 dinosaurs in a specific Jurassic World Exhibit. Some are T-Rexes and some are triceratops. There are 92 legs total in the exhibit. Create 2 equations to represent this
situation. How many of each type dinosaur is there? (Assume that all of the dinosaurs have
the correct number of limbs.)

9514 1404 393

Step-by-step explanation:

For this we have to assume that the T-Rex has only 2 legs. Let r represent the number of T-Rex, and t represent the number of triceratops. The problem statement tells of two relationships:

  r + t = 25 . . . . . . total number of dinosaurs in the exhibit

  2r +4t = 92 . . . . total number of legs in the exhibit

__

Multiplying the second equation by 1/2 and subtracting the first, we find ...

  (1/2)(2r +4t) -(r +t) = 1/2(92) -(25)

  t = 21 . . . . . . simplify

  r = 25 -21 = 4

There are 4 T-Rex, and 21 triceratops.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
