Answer:
x = 15
The median is the middle number, however, in this case there are two:
25 and x
The formula is:
23 + x/2 = 30.5
Subtract 23 from both sides:
23 + x - 23 = 30.5 - 23
Simplify:
x/2 = 7.5
Multiply both sides by 2:
2x/2 = 7.5 ⋅ 2
Therefore:
x = 15
Answer:
g = 3
Step-by-step explanation:
(x+7)(x-4) = x²+ gx -28
Multiply the two parenthesis
(x+7)(x-4)= x² -4x +7x -28
Combine like terms
(x+7)(x-4)= x²+3x-28
Compare the equations
x²+ gx -28 = x² +3x -28
g = 3

Answer: C and E
Step-by-step explanation:
The plane starts at 32,460 feet.
It then ascends 1645 feet. Ascending means it's going up higher. So we add.
32,460 + 1645 = 34,105 (C)
From here (34,105 feet) the plane descends by 3/5 of it's height. Descending means it's lowering. So we subtract.
But first we have to figure out how much we are subtracting.
3/5 is equal to .6
Multiply to find 3/5 of current height.
34,105 × .6 = 20,463
So the plane descends by 20,463 feet.
34,105 - 20,463 = 13,642 feet (E)
