System of equations to be solved simultaneously
Answer:
3 1/3 Hz
Step-by-step explanation:
Frequency is measured in "cycles per second," now given the name "hertz". The number of cycles per second is ...
(15 m/s)/(4.5 m) = 3 1/3 Hz
B-(-7)= -1
First negative multiply by negative is POSITIVE.
So: B+7= -1
Subtract 7 from both sides
B= -7-1
B= -8.
Answer: -8.
To Check Answer: Plug in the variable of B in the original equation.
So: -8-(-7)= -1
-8+7= -1
-1= -1
If the Solution works out the answer is right.
Answer:
b1 = (2A/h) - b
Step-by-step explanation:
Follow these steps to solve:
A= h ( b1 + b2 ) / 2
2A = h (b1 + b2)
2A/h = b1 + b2
(2A/h) - b2 = b1
b1 = (2A/h) - b2
