9x is the answer
Step-by-step explanation:
-x-(-10x)
-x+10x
9x
Answer:
b = -T²/k(k-m) + k
Step-by-step explanation:
Given the equation T =√k(k-b)(k-m), we are to make b the subject of the formula
Square both sides
T² = (√k(k-b)(k-m))²
T² = k(k-b)(k-m)
T²/k(k-m) = k-b
Rearrange
k - b = T²/k(k-m)
b - k = - T²/k(k-m)
Add j=k to both sides
b - k + k = - T²/k(k-m) + k
b = -T²/k(k-m) + k
This gives the required expression
Answer:
The first option
Step-by-step explanation:
The correct answer is the first option, since E(black) = 0.24 and E(red) = 0.16, Seth should choose to play black marbles.
3x+2+x+8=180; 4x+10=180; 4x=170; x= 170/4= 42.5
Angle on top is x+8=42.5+8=50.8
Angle on the bottom is 3x+2=3•42.5+2= 129.5
Answer:
x = 13 1/2
Step-by-step explanation:
16x -12x+0=54
combine like terms
4x + 0 = 54
4x = 54
divide each side by 4
4x/4 = 54 /4
x = 54/4
x = 13 2/4
x = 13 1/2
