Answer:
Step-by-step explanation:
25. 
Combine like terms. 
4t+7=-33
subtract 7 from both sides
4t=-40
divide both sides by 4
t=-10
26.
Subtract 2a from both sides
5=7a-16
add 16 to both sides
21=7a
divideby 7 on both sides
a = 3

Hey You! 
The integer would be: -25, because Mr. Williams was below sea level, and not above, so the integer that would represent this situation would be a negative integer.
That's Your Answer! ^^
        
             
        
        
        
In case of plane, for y intercept, x and z are o .
So we will get
4(0)+5y-0=20
5y=20
Dividing both sides by 5
y = 4
So the y intercept is (0,4,0).
In second question, x intercept is 1, y intercept is -1 and z intercept is 2 . 
So the correct option is the third equation , that is x-y+2z=4 .
