Answer:
The solution to the system of linear equations
i.e. (x, y) = (2, 4)
The graph is also attached.
Step-by-step explanation:
Given the system of linear equations
solving the system
Arrange equation variables for elimination
solve for x
Divide both sides by 2
Thus, the solution to the system of linear equations
i.e. (x, y) = (2, 4)
The graph is also attached.
Answer:
0
Step-by-step explanation:
12 + 8 = 20
If we then take 20 from 20, you get 0.

Answer:
hmm
Step-by-step explanation:
Given:
quarters and dimes ; 19 pcs
total value of quarters and dimes is 4
q + d = 19
0.25q + 0.10d = 4
q = 19 - d
0.25(19 - d) + 0.10d = 4
4.75 - 0.25d + 0.10d = 4
-0.15d = 4 - 4.75
-0.15d = -0.75
d = -0.75/ -0.15
d = 5
q = 19 - d
q = 19 - 5
q = 14
There are 5 pieces of dimes and 14 pieces of quarters.
