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:
44.6 mph
Step-by-step explanation:
200.7/4.5=44.6 mph
6x+3x+8=35
Step 1: Simplify both sides of the equation.
6x+3x+8=35
(6x+3x)+(8)=35(Combine Like Terms)
9x+8=35
9x+8=35
Step 2: Subtract 8 from both sides.
9x+8−8=35−8
9x=27
Step 3: Divide both sides by 9.
9x

x=3
Answer:
x=3
12w−5−3w=40
Step 1: Simplify both sides of the equation.
12w−5−3w=40
12w+−5+−3w=40
(12w+−3w)+(−5)=40(Combine Like Terms)
9w+−5=40
9w−5=40
Step 2: Add 5 to both sides.
9w−5+5=40+5
9w=45
Step 3: Divide both sides by 9.
9w
9
=
45

w=5
Answer:
w=5
Answer:
The temperature dropped 12 degrees over 3 hours. How much did it change each hour?
Step-by-step explanation:
This question (the answer) is asking you to do 12 divided by 3. That would be 12/3 (which is what was in the original question). Also, the temperature dropped, so that would be why it is -12/3
