Answer:
x = 0
Step-by-step explanation:
Step 1: Write equation
4x - 5 - 2x = x - 5
Step 2: Solve for <em>x</em>
- Combine like terms: 2x - 5 = x - 5
- Subtract x on both sides: x - 5 = -5
- Add 5 to both sides: x = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
4(0) - 5 - 2(0) = 0 - 5
0 - 5 - 0 = -5
-5 = -5
Answer:
D. Brea lives the farthest from school
Step-by-step explanation:
The easiest way to go about this is to get them all to the same unit. Let's do meters :)
3 kilometers = 3,000 meters (Kai)
30,000 centimeters = 300 meters (Cal)
and then of course 30,000 meters is already in the correct unit (Brea)
Given all of this, you can easily tell that the answer is D
Yes and no. A negative number and it's opposite are 'integers.' Yes, a negative and a negative multiplied together give you a positive. The two negative signs cancel out making it positive. But no, a positive and a positive multiplied together do not give you a negative. When you subtract positive numbers you can get a negative, but not when multiplying. If you were to do a positive times a negative it would be negative because the positive can't cancel it out. Example: -3 · -3 = 9. [] 3 · 3 = 9. [] -3 · 3 = -9. Other than the positive number part, the statement is true about the negatives. I hope that helped!
