The answer is x=-7 and x=-1
Answer:
220
Step-by-step explanation:
We have given that Colin scored 25 and Brian scored x ( x-unknown)
Since we know that Brian scored 170 more than Colin, Brian scored:
x = 25 + 170 = 195
Now we know that Colin scored 25 and Brian scored 195.
They together scored
25 + 195 = 220
The impulse that was produced by this aircraft jet engine is 5,400 Ns.
<u>Given the following data:</u>
To determine the impulse that was produced by this aircraft jet engine:
<h3>How to calculate
impulse.</h3>
Mathematically, impulse is given by this formula:

<u>Where:</u>
- F is the force or thrust.
- t is the time measured in seconds.
Substituting the given parameters into the formula, we have;

Impulse, I = 5,400 Ns.

$450 bc 25% more is $500 and 10% is $50 so $500 -$50 is $450
