Answer:
I'm not sure if the warm up speed is less than the cool down speed. If it is different than how I did it you just need to swap their positions on the y axis, so the "lumps" or whatever you want to call the shapes will be in opposite positions. The middle one will stay the same because it is the fastest and in between the two happening. Also let me know if you can't read any of the labels
9 = x
subtract 3x from both sides of the equation and you're left with 9=x
75+d=110 subtract 75 from both sides
d=$35
So she needs to deposit at least $35 to be able to pay the electric bill.
60 min = 1 hour
1st we need to know how many times 20 goes in 60 so we will divide.
60 ÷ 20 = 3
Now we will multiply to find the trains speed in miles per hour.
3 × 25 = 75
SO, the train travels 75 miles per hour.
Hope I helped ya!!
