Answer:
5=b
Step-by-step explanation:
Eliminate the parenthiesies --> n-2+7 = bn
Move the variables to one side (they cancel eachother out) --> -2+7 = bn
Solve --> 5=b
Answer:
Step-by-step explanation:
Given the equation of motion;
S = ut + 1/2 at² where;
u is the initial velocity,
a is the acceleration, and;
t is the time.
We are to express a in terms of u, t and S
Making a the subject of the formula;
S = ut + 1/2 at²
S-ut = 1/2at²
2(S-ut) = at²
a = 2(S-ut)/t²
Hence the acceleration a in terms of other variables is expressed as a = 2(S-ut)/t²
Answer:
x < 8
Step-by-step explanation:
Add 4 to both sides
5x=40
Divide by 4
x < 8
