For this case we have the following expression:
Applying distributive property to the terms within parentheses we have:
We add similar terms on both sides of equality considering that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.
We add 7.5x to both sides of equality:
We subtract 72 from both sides of equality:
We divide between 3 on both sides of equality
ANswer:
Distributive property
Add similar terms
Equality property of the sum
Equality subtraction property
Equality property of the division
Answer:
Average cost per litre of diesel = rs 8.00
Step-by-step explanation:
Amount spent on diesel each year = rs 4000
Price of a litre of diesel in the first year = rs 7.50
Price of a litre of diesel in the second year = rs 8.00
Price of a litre of diesel in the third year = rs 8.50
Average cost per litre of diesel = 
where n is the number of years.
Average cost per litre of diesel = 
= 
= 8
Average cost per litre of diesel is rs 8.00
So that he buys an average of 500 (i.e 
) litres every year.
Answer:

Answer:
The answer I got was 15 3/4 ft 2
Answer:
11
Step-by-step explanation:
Evaluate using
PEMDAS
First we do what is inside of the Parenthesis 12 - 9 = 3
Now we have 2 + 3²
Next is Exponents 3² = 9
Now we have 2 + 9
there is no multiplication or division needed so we go straight to addition
9 + 2 = 11
So we can conclude that the answer is 11
