9(2) + 2(y) = 50. solve for y. 32=2y, y=16. It is 16 meters long.
Answer:
Step-by-step explanation:
we see that y = -3x-3
substitute that into the other equation to get
-3x-3 = 2x+7
-5x = 10
x = -2
so, y = -3(-2)-3 = 3
check to make sure (-2,3) solves both equations.
Divide 754 by 13 and you get 58
Now multiply by 9 and you get 522 miles.
Answer:
initial speed: 240 m/h
Step-by-step explanation:
48 m/h is the current speed which is the 20% of X
x (20 / 100) = 48
20x = 4800
x = 4800/20
x = 240 m/h
Can you describe it a little more- I have no clue how I’m suppose to solve that.
