Answer:
x = 27 and y = 17 is the solution the the given pair of equations.
Number of dinosaur's rib = x = 27
Number of dinosaur's arm = y = 17
Step-by-step explanation:
We are given the following equations:
[tex]y = 0.5x + 3.5 \\y = -0.75x + 37.25[/tex]
The dinosaur's ribs and arms are the solution to the system of given equations.
Solving the equations, we have:
[tex]y = 0.5x + 3.5 \\y = -0.75x + 37.25\\\Rightarrow 0.5x = 3.5 = -0.75x + 37.25\\\Rightarrow 1.25x = 33.75\\\Rightarrow x = 27\\\Rightarrow y = (0.5)27 + 3.5\\\Rightarrow y = 17[/tex]
Thus, x = 27 and y = 17 is the solution the the given pair of equations.
Number of dinosaur's rib = x = 27
Number of dinosaur's arm = y = 17
