Answer:
Step-by-step explanation:
If the new height is 338m and the helicopter decended 127m to get to that new height then the original height is simply the sum of them both.
H = 338m + 127m
H = 465m
Answer:
(x, y) = (2 2/9, -1 4/9)
Step-by-step explanation:
Equate the values of y and solve for x.
1/4x -2 = -2x +3
(2 1/4)x = 5 . . . . . . . . add 2+2x to both sides
x = 20/9 = 2 2/9 . . . multiply by 4/9
y = -2(2 2/9) +3 = -4 4/9 +3 . . . . substitute for x in the second equation
y = -1 4/9
The solution is x = 2 2/9, y = -1 4/9.
Answer:
x=2
Step-by-step explanation:
0=-2x+4
add -2x on both sides
2x=4
divide by 2
x=2

</span><span>Simplify:
</span><span><span><span>−n</span>+25</span>=32
</span>Subtract 25 from both sides.
<span><span><span><span>−n</span>+25</span>−25</span>=<span>32−25
