Answer:
g = -3
Step-by-step explanation:
10g-4(g-2)+11=1
1) 10g-4g+8+11=1 Combine like terms
2) 6g+8+11=1
3) 6g+19=1
4) 6g=-18 To continue the process of getting the variable by itself, we have to get rid of 19. So we are going to subtract 19 from 19 to get 0, and whatever we do to the other side, so we subtract 19 from 1 to get -18.
5)6g=-18 To get the variable by itself, instead of mutiplying, we will divide by 6 on both sides to get... g=-3! Hope this helps!
Answer:
Step-by-step explanation:
Lets call 
the the still-air speed of the plane and 
the speed of the wind. On the first part the speed of the plane relative to the ground will be 
, and on the second part it will be 
.
We know that the distance d=400 miles on the first and second parts are the same, so by the definition of velocity we will have:
Or:
Adding both equations:
Which for our values is:
If instead of adding, we substact, we would have:
Which for our values is:

Answer:
10x+15
Step-by-step explanation:
area of the two rectangles combined is one big rectangle
area of rectange= base*height
base length: 2x+3
height: 5
(2x+3)*5
=(2x*5)+(3*5)
=10x+15
Random letters so i can just put the answer
325.50 i think
