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
Hello and Good Morning/Afternoon
<u>Let's take this problem step by step.</u>
<u>What did we do in this problem</u>
- we ensured that both sides remained equally balanced in value
- took everything step-by-step to make sure that there were no mistakes
- to check it, we can plug it back into the original equation to see if it works
<u>Answer: x = 6</u>

Answer:
5 and 4
Step-by-step explanation:
So if, x equals 2 then all you do is turn the x into a 2.
So you rewrite the equation into,
2 + 3 and 2 x 2,
Which would be 5 and 4
Hope this helps!

<span>The correct answer is: 21
Explanation:
Let's first assume few variables!
x = Ishann's age (in years)
y = Christopher's age (in years)
1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)
2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)
Get the value of y from Equation (1) and plug it in Equation (2):
(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21
Hence Ishann is 21 years old!</span>
