Answer:
I do know that y = 3 and that x = -2, so any system that has that solution is correct.
Step-by-step explanation:
Multiplying the second equation by -2 and adding the equations will cancel out the x variable. The remaining equation is:
10y = 30. Therefore, y must be 3. Substituting y in for the first equation, we get:
6x + 6 = -6. That means x must be -2. I checked my work with the second equation:
-6 - 12 = -18.
The system results in a true statement, so the answer is y = 3 and x = -2.
I only have one and it's 180-65=angle2 angle2=angle1 so 180-65=angle1
I’m not sure about the answer, but my name is Jessica ✌
Answer:
12 2/3 km/hour or 12.666 km/hour
Step-by-step explanation:
Because 3 1/6 is the rate for every quarter hour, simply multiply that rate by 4 in order to get the average speed over the course of an hour.
Solve: 12 - 2x = -2(y - x)
Steps:
1. Expand -2(y - x): -2y + 2x
12 - 2x = -2y + 2x
2. Then subtract 12 from both sides
12 - 12 - 2x = -2y + 2x - 12
3. Simplify,
-2x = -2y + 2x - 12
4. Then, subtract 2x from both sides
-2x - 2x = -2y + 2x - 2x - 12
5. Simplify,
-4x = -2y - 12
6. Then, divide both sides by -4
-4x/-4 = -2y/-4 - 12/-4
7. Simplify,
x = 1/2y + 3 <======= <em>Answer</em>
Hope this helped!!!!
