10 - 2.99 = 7.01 and 7.01 - 1.07 = 5.94 so you will get 5.94 in change
Answer:
Train A = 299 tons Train B = 50 tons
Step-by-step explanation:
Train A = x
Train B = y
x+y = 349
x= y +249
Plug in one equation into another
y+249+y= 349
Simplify
2y+249=349
Subtract 249 from both sides
2y=100
Divide both sides by 2
y=50
Plug it into the x equation to solve for x
x+50=349
-50 from both sides
x=299

<span> (0, 2) (3, 0)
slope = (2-0)/(0-3) = -2/3
perpendicular lines, slope is opposite and reciprocal
so </span><span>the slope of a line that is perpendicular to the line is 3/2
answer
3/2</span>
