Answer:
2x = 3x-5
Step-by-step explanation:
<em>Complement</em> = 90-x
<em>Supplement</em>=180-x
180-x=4(90-x)+6
180-x=360-4x+6
3x=360-180+6
3x=186
x=186/3
x=62
Note that 5x appears on both sides of this equation. Delete 5x from each side. This leaves us with 3x = 15/2. Dividing both sides by 3 results in x = 5/2 (ans)
Answer:
The integer would -3.
Step-by-step explanation:
Think of it this way:
The elevator goes +7 (Positive = Up) and then -4 (Negative = Down). What is 7-4? That's easy it's just 3. But since the floor level goes down, <u>it would be negative.</u> So you just make it -3.
Check your work:
If we went up from the 4th floor by three, we would get up to the 7th floor.
Hope it Helps!
