Step-by-step explanation:
Let m be the price of 1 baby mice
Let p be the price of 1 baby python
Given,
![3m + 2p = 103.50](https://tex.z-dn.net/?f=3m%20%2B%202p%20%3D%20103.50)
as equation 1.
and
![3m + 3p = 148.50](https://tex.z-dn.net/?f=3m%20%2B%203p%20%3D%20148.50)
as equation 2
From here we can easily use elimination method
for solving simultaneous equations.
Use Equation 1 - equation 2 to eliminate m to find p.
![(3m - 3m) + (2p - 3p) = 103.50 - 148.50 \\ - p = - 45 \\ p = 45](https://tex.z-dn.net/?f=%283m%20-%203m%29%20%2B%20%282p%20-%203p%29%20%3D%20103.50%20-%20148.50%20%5C%5C%20%20-%20p%20%3D%20%20-%2045%20%5C%5C%20p%20%3D%2045)
Substitute p into equation 1.
![3m + 2(45) = 103.50 \\ 3m + 90 = 103.50 \\ 3m = 103.50 - 90 \\ 3m = 13.50 \\ m = 13.50 \div 3 \\ = 4.50](https://tex.z-dn.net/?f=3m%20%2B%202%2845%29%20%3D%20103.50%20%5C%5C%203m%20%2B%2090%20%3D%20103.50%20%5C%5C%203m%20%3D%20103.50%20-%2090%20%5C%5C%203m%20%3D%2013.50%20%5C%5C%20m%20%3D%2013.50%20%5Cdiv%203%20%5C%5C%20%20%3D%204.50)
therefore 1 baby mice cost $4.50 and 1 baby python costs $45.
Answer:

Step-by-step explanation:
3^-7 x 3^7 = 1
The negative exponents put it in the denominator
1/ 3*3*3*3*3*3*3 * (3*3*3*3*3*3*3) = 1
The 3's cancel leaving
1/1 = 1
1=1

Answer:
The solution of the system is
x=8, y=11
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The intersection point is (8,11)
see the attached figure
therefore
The solution of the system is
x=8, y=11
