Shrubs and trees regrow quickly in an area that has been burned during a forest fire.
Algae,grasses, and other small plants grow on newly exposed rock over a long period of time.
Answer:
Answer is in the explanation.
Explanation:
Let's make a system of equations.
5x+10y=550
x+y=80
Now let's use elimination
-5x-5y=-400
5x+10y=550
__________
5y=150
y=30
Then subsitute 30 in for y to find x. This will leave you with x=50. You will have 50 $5 bills and 30 $10 bills. You can check by subsituting x for 50 and y for 30 in both equations to show why it is correct. Eliminating makes it easier to solve the system of equations.
