Answer:
The answer is -1200 +3(60)
Step-by-step explanation:
If the submarine is 1200 feet below sea level, that means that the submarine's level is -1200. If you rise by 60 in a 3 hour period, you rise by 60 every 3 hours. So if your rising by 60 feet, 60 is not a negative, and the equation would be -1200+3(60). Hope this helped! :D
Answer:
67
Step-by-step explanation:
Since the diagonals in a rectangle are congruent, AC=BD and
7x+18=10x-3
We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in
18=3x-3
Next, add 3 to both sides to get
21=3x
Divide both sides by 3 to get
x=7
Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67
Answer:
36
Step-by-step explanation:
56=7-3[4+{8-4(4+5-3)}]
56=7-3[4+{4(4+5-3)}]
56=7-3[4+{16+20-12)}]
56=7-3[4+24]
56=4[28]
56=92
56-56=92-56
36
1= -6
2= -5
3= -4
4= -3
5= 0
6= 3
