We're comparing 80,000 with 80.
One way to do this is divide the two numbers: 80,000/80 = 1000.
80,000 is one thousand times greater than 80.
8x+1500 is the needed expression.
221.57
Explanation:
To round to the nearest tenth you would would look at the hundredths place. If it is higher than 5 you round the number in the tenth place up if it is lower than 5 you keep it the number in the tenth place the same. In this case you have 2 which is lower than 5 so you keep the 7 the same and bring everything else down.
=-35(4s-t)+21(4s-t)
=-140s+35t+84s-21t
=-140s+84s+35t-21t
=-56s+14t
