Answer:
there will be 19 $100 bills
and 11 $10 bills
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
Let x be how many $10 bills there are.
Let y be how many $100 bills there are
x + y = 30
x = 30 - y
10x + 100y = 2010
10(30 - y) + 100y = 2010
300 - 10y + 100y = 2010
-10y + 100y = 2010 - 300
90y = 1710
y = 1710 / 90
y = 19
x = 30 - 19
x = 11

Answer 1 is $67.54 and answer 2 is 6. hope this helps. brainliest please
y = x² + 6x + 5
Use the formula: -b/2a
a = 1
b = 6
- 6 / 2
= -3
The x-coordinate of the vertex is -3
Plug the x value back into the original equation to find the y-coordinate of the vertex
y = (-3)² + 6(-3) + 5
y = -4
<h3>Answer: (-3,-4)</h3>
