I'm not sure how many equations you are asking for, but hopefully, you can use what I wrote here to solve your actual question. Here is my go:
3x+10+2x+2+5x
First, add all the x's together:
3x+2x+5x=10x
Next, add all our numerals together:
10+2=12
Put it together!
10x+12
C: is the speed of light (3*10^8 m/s) and it is squared (raised to the power 2) in this equation.
Since the dimension of the scale model is fourth of dimensions of the room, divide by 4 the given dimensions.
new dimensions:
= 18 ft / 4 = 9/2 ft
= 16 ft / 4 = 4 ft
The area is calculated by multiplying the dimensions,
Area = (9/2 ft)(4 ft) = 18 ft²
Therefore, the area of the scale model is equal to 18 ft².
Bus 1 : 194 miles / 4 hours = 48.5 miles / hour.
Bus 2: 245 miles / 5 hours = 49 miles / hour.
Bus 2 is faster.
