To find the total cost, you need to add these numbers together
you get 7.37 as your answer, but you need to round this to the nearest whole number.
rounding 7.37 will make it 7.
the total cost is about $7
Answer:
$10.67
Step-by-step explanation:
Jennifer has a total amount of $80 to buy what she needs
1/5 of the money is spent on sandwich
= 1/5×80
= $16
The amount spent on sandwich is $16
1/6 of the money is spent on tickets to a museum
= 1/6×80
= 0.166×80
= $13.33
The amount spent on tickets is $13.33
1/2 of the money is spent on a book
= 1/2×80
= 0.5×80
= $40
The amount spent on a book is $40
Therefore, to calculate the amount left on her we add the total money spent and subtract it from the original amount of money that she has to spend
= $80-$16+$13.33+$40
= $80-$69.33
= $10.67
Hence the amount of money left on Jennifer is $10.67
Answer:
18
Step-by-step explanation:
2 times 3 to the power of 2 is 18
<span>(-7w^2 - 2w - 1) - (-5w^2 + 3w - 2)
Take out of parenthesis according to the symbol outside of them. In this case it is a negative so everything in the parenthesis will be opposite of what it is.
-7w^2 - 2w -1 + 5w^2 - 3w +2
Combine like terms.
-2^2 - 5w + 1
^^^^^ That is your official answer.
You cannot continue to simplify because there are no like terms to simplify and it would just not make sense to further simplify. Hope this helps. :) </span><span>
