Darien ordered soda for $2.75, a sandwich for $8.50, and a dessert for $3.85. Sales tax was $1.15. Use mental math to find the t
natta225 [31]
What I would do is start with the price of the dessert and the sales tax $3.85+ $1.15= $5. I started with this because when you add the cents they equal a dollar which makes it easier to continue.


Then I would add the 2.75. This would be 7.75.


Then add 7.75 + 8.50. To simplify this, you can add 7 + 8, then .75+ .50

Which would equal 15 + 1.25 + 16.25

FromTheMoon [43]

Answer:

a.  F = (9/5)(K - 273.15) + 32

b.  F = 32°F

Step-by-step explanation:

K=5/9(F−32)+273.15

F = (9/5)(K - 273.15) + 32

F = (9/5)(<u>273.15</u> - 273.15) + 32

State the degree and leading coefficient of each polynomial in one variable -12-8x^2+5x-21x^7
leonid [27]

Answer:

The degree is 7 and the leading coefficient is -21.

Step-by-step explanation:

The degree of an equation is found using the highest exponent on the variable in the equation.

-12-8x^2+5x-21x^7 has the term x^7 so its degree is 7

The leading coefficient is the coefficient of the term with the highest degree. The coefficient of x^7 is -21.
