X—2 equations combined:
2(2x - 3y) + 3(5x + 2y) = 2(11) + 3(18)
4x - 6y + 15x + 6y = 22 + 54
19x = 76
x = 4
y—1st equation, substitute x:
2(4) - 3y = 11
8 - 3y = 11
3y = - 3
y = - 1
Answer: x = 4, y = - 1
Proof—2nd equation:
5(4) + 2(- 1) = 18
20 - 2 = 18
18 = 18
Answer:
2,0
Step-by-step explanation:
Sorry if I got it wrong.
Answer:
The answer is miles.
Step-by-step explanation:
To solve this is pretty easy,
We know that the equation is , and since we have to find the distance in 21 seconds, you just have to substitute the variable.
