It would be 2.5E-2 or with the power of 10 it would be 2.5 x 10^-2
Answer:
385 cubes
Step-by-step explanation:
11*7*5=385 cubes
The example for an inconsistent system of equations:
x + 2 y = 10 and x + 2 y = 20. If we try to solve it algebraically:
x = 10 - 2 y; 10 - 2 y + 2 y = 20; 10 = 20 ( not true ). We will with something that is not true. Graph of those equations shows 2 parallel lines. Therefore the system is inconsistent.
The system is dependent when we have equivalent equations. For example:
2 x + y = 5 and 4 x + 2 y = 10. If we try to solve this system, we will end up with: 0 = 0 ( true ). The graph of this system shows the same line. This system is dependent.
Finally, if we have just one solution for the system of equations then the system is independent. For example: x + y = 5 and - x + 2 y = 10. When we add those equations: 3 y = 15; y = 15 : 3; y = 5; x + 5 = 5; x = 0. So we have just one solution ( x , y ) = ( 0, 5 ). The system of equations is independent.
Answer: it would take 22 hours before you pay the same amount for both Garages.
Step-by-step explanation:
Let x represent the number of hours that you park at either Garage A or Garage B
Let y represent the total amount paid for x hours at Garage A
Let z represent the total amount paid for x hours at Garage B
Garage A charges $11 for the first 2 hours of parking there and then $3 per hour after the first 2 hours. This means that the total amount for x hours would be
y = 2 × 11 + 3x
y = 22 + 3x
Garage B charges $4 per hours. This means that the total amount for x hours would be
z = 4x
To determine the number of hours before the amount for both Garages becomes the same, we would equate y to z. It becomes
22 + 3x = 4x
4x - 3x = 22
x = 22
