Step-by-step explanation:
Answer:
3t
Step-by-step explanation:
1 you would change +10 to -10 and subtract 10 from 160.
2. you would end up with 50t = 150 after doing that
3. divide 50 by 50 to isolate the t. now t is by itself since 50 divided by 50 is 1.
4. divide 150 by 50 to get 3. the t is still there so it's t=3 or just 3t
lmk if i should explain this better or if you still need assistance
Answer:
4'9"
Method 1:
First, convert both numbers into inches. Remember that 1' = 12", and the rest is like a remainder.
7'5" = (7*12)+5 = 84+5 = 89
2'8" = (2*12)+8 = 24+8 = 32
Next, subtract the two numbers.
89 - 32 = ?
89 - 32 = 57
There's your answer! You can change it back into feet by dividing it by 12.
57 / 12 = 4.75 = 4'9"
Method 2:
Another way of solving this problem is to borrow from the "feet" place.
7'5" - 2'8"
You can't take 8 away from 5, so you borrow from the "feet" place. Remember that unlike normal borrowing, you need to add 12 instead of adding 10.
6'17" - 2'8" = 4'9"
Whichever method you choose, you should get the same answer!
