Answer:
and 
Step-by-step explanation:
Given:
Equation 1:

Simplifying the above equation by dividing both sides by 100


Equation 2:

Simplifying the above equation by dividing both sides by 400.


Now the system of equation is:
(1a) 
(2a) 
Solving by elimination
Multiplying equation (2a) with 

(2b) 
Adding equations (1a) and (2b) in order to eliminate 

+ 
We get 
∴ 
Plugging
in equation (2a).

Adding
both sides.

∴ 
Answer:
10
Step-by-step explanation:
X = -1 so, we have:
3·1² + 1
3² + 1
9 + 1
10
that would be 48/9 because it would be kittens(48) to puppies(9) then simplified to 16/3.
Answer:
x = 5
Step-by-step explanation:
Maybe you have ...
n(x) = 2x +7
and you want x for n(x) = 17.
17 = 2x +7
10 = 2x . . . . . . subtract 7
5 = x . . . . . . . . divide by 2
