Answer:
x = −2
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(−3x+4)+3x−3=−29
Step 1: Simplify both sides of the equation.
−2(−3x+4)+3x−3=−29
(−2)(−3x)+(−2)(4)+3x+−3=−29(Distribute)
6x+−8+3x+−3=−29
(6x+3x)+(−8+−3)=−29(Combine Like Terms)
9x+−11=−29
9x−11=−29
Step 2: Add 11 to both sides.
9x−11+11=−29+11
9x=−18
Step 3: Divide both sides by 9.
9x
/9 = −18
/9
x=−2

Answer:
8.94 (Rounded would be 9)
Step-by-step explanation:
By using the Pythagorean Theorem formula,
A^2+B^2 = C^2
You have the hypotenuse (c) = 12
and you have a leg (a) = 8
and you're trying to find another leg (b) = x
In order to find this, you'll have to change up the formula in order to find (B) instead of (C)
B^2 = C^2 - A^2
(B) = (12)^2 - (8)^2
(B) = 144 - 64
(B) = 80
Square root of 80
B = 8.9
200+40=240
each train cost 10
take 240/10=24trains
