(3+1)+(8y-2y+4y)
4+10y
Answer:
Step-by-step explanation:
Now the key here is manipulating the scale:
For 3 every 2cm = 15mi
Divide by 2 so every 1cm = 7.5mi
So if we had 16.27cm then that would equal 16.27 x 7.5 = 122.025mi on the actual scale
Same for 4: if 1/2cm = 20mi
Then multiply times 2 and every 1cm = 40mi
So 11.73cm x 40 = 469.2mi on the actual scale
Hopefully this is right and it helps!
