I think the answer is 816cm
Answer:
x=30 x=-20
Step-by-step explanation:
We can use the zero product property to set the factors equal to zero
x-30 = 0 and x+20 =0
x=30 x=-20
Hello!
As our x-values are the same, we find the difference in our y-values, which are 8 and 3.
Therefore, our answer is B) Subtract 8-3.
I hope this helps!
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.
