Answer:
The system that models the situation is:

The solution is:
(9, 6)
Step-by-step explanation:
We must write the equations as indicated in the problem.
The sum of twice a number and another number is 24
<em>a number:</em> x
<em>other number:</em> y
Then

The difference of twice the first number and the other number is 12
<em>first number: </em> x
<em>other number:</em> y
Then:

The system that models the situation is:

To solve the system we add both equations to find the value of x

Answer:
can you help me
Step-by-step explanation:
Answer: 17 inches
Explanation: so we have a triangle with the two side lengths 8 and 15 and we’re trying to find the hypotenuse. so using the pythagorean theorem, we have 8^2 + 15^2 = c^2. when we solve we get 64 + 225 = c^2, which is 289 = c^2. next, we find the square root of both sides and c = 17 inches.

250m/s = x m/min
250m/s = x min/ 60s
250•60 = 1500
The airplane will travel 1500m per minute
