Steps in pic below
9= h/9
Mutiply both sides by 9

9*9= 81
Answer: h= 81

Answer:
Only Jude
Step-by-step explanation:
To show 28 x 2 we show 14 x 2 x 2
The x would be cancelled out in this process so x *x would work to enable a product of 56.
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
