17ft 8in = 212 in so according to the options I would say go with 165 so A.
Answer:
Kindly check explanation
Step-by-step explanation:
When performing addition and subtraction of decimals, it is important to arrange the numbers being added or subtracted such that the decimal points are in line. This is particularly important so that the place value of the numbers are in accord.
To simplify, when then decimals are in line, then the tenth value of the first number will be added to the tenth value of the second. Without this arrangement, one might be adding the hundredth placed value to the tenth or unit value which is mathematically incorrect and will yield a wrong result.
For instance :
6.32 - 0.5
Here, when the decimal point of each number is in line, the tenth placed value of the first number (3) matches the tenth placed number of the second number (5) and all others also fall in place automatically.
____6.32
- ___0.5
________
___ 5.82
________
The answer is 5 because 10 divided by 2 is 5
2 + 2 x 4 - 16 = -6
How?
Use PEMDAS.
The first step that shows up is multiplication.
2 + 8 - 16
Next comes Addition.
10 - 16
-6
Using the sum (addition) and two 2-digit addends, 12 + 34 can be answered without regrouping.
