Answer: I think its 131.19, but not too sure.
Step-by-step explanation:
To find the speed, you would do distance/time, so I added 300 and 7. I got 307, then I divided 307 (distance) from 2.34 (time). I got 131.19
Do you want the speed of both cars? then the answer would be:
(300)- first car= 128.20
(307)- second car= 131.19 (if you need to round this answer, it would be 131.2)
A=(x+y)/z
A*z=((x+y)/z)*z
Az=x+y
Az-x=x+y-x
Az-x=y
so y=Az-x
Answer:
x = 5
Step-by-step explanation:
Sub the equation x - 1 in place for the x in the top equation. So -3x + 5(x - 1) = 5
-3x + 5x - 5 = 5
Add 5 to get 2x = 10
Divide both sides by 2 to get x = 5
