Answer:
C
Step-by-step explanation:
The step shown indicates that y was eliminated from the equations. For choices A, B, D, this is done by adding the equations together (the y-coefficients are opposites). The result of doing that gives x-terms of 4x, 0x, and 0x, respectively. These x-terms do not match the one given: 2x.
For choice C, the y-term is eliminated by subtracting twice the second equation from the first. Doing that gives ...
(4x +2y) -2(x +y) = (14) -2(3)
4x +2y -2x -2y = 14 -6 . . . . eliminate parentheses
2x = 8 . . . . . . . . . . . . . . collect terms
Answer:
you multiply by -4 each time.
Step-by-step explanation:
4 x -4= -16
-16 x -4 = 64
64 x -4 = -256
hope this helps
Please keep in mind that the answers may not be correct. I have tried my best to answer.
1. 83.333...% would fit. We must first solve for x. As you can see, we have a similarity in the picture. 16 and 4. It's 4. So, we multiply that by 6 which equal 24=x. Now, we know that space (Not provided) is 4. So, we just divide 20 by 4. It will equal 5, add the space not provided and becomes 6. All you gotta do is now divide 100/6. 16.666... Multiply by 5 since that is how much it is providing. Then, your answer will be 83.333...%
2. 88.888...% would fit. Like the above, we must solve for x. As you can tell, the situation is similar to the original. Divide 18 by 4, 4.5. Multiply 6 by 4.5, 27. Subtract 27 by 24, 3. Now we know that the space (not provided) is 3. Divide 24" by 3, 8. Add 1 due to the non provided space. 9. Divide 9 by 100, 11.111... Multiply by 8 and get the answer. 88.888...%
La propiedad distributiva es una propiedad de las matemáticas de “distribuir” un múltiplo a una expresión.
La propiedad distributiva es lo opuesto a factorizar.
