Answer:
your answer would be D. x = 2.5 + y
Step-by-step explanation:
The diameter would be d≈288.85!
I hope this helped! Brainliest? :) -Raven❤️
Let x = speed of the first car
the second car is 12 km slower so the seconds car speed is x-12
they each drove 2 hours so 1st car = 2x
2nd car = 2(x-12)
they drove 360 km
so you have 2x + 2(x-12) = 360
solve for x
2x+2(x-12) = 360
2x + 2x-24 = 360
4x-24 = 360
4x = 384
x = 384/4
x = 96
1st car drove at 96 km per hour
slower car drove at 96-12 = 84 km per hour
Hey!!
here is your answer >>>
let's find x first ,
2x + 48 = 180
2x = 132
x = 66!.
there is a right angle,
the angle below the right angle is also 90°
angle y would be ,
180 - (90+ 48)
180- 138
=> 42
answer is 42!.
