Considering the definition of an equation and the way to solve it, the total cost of the shoes is 0.20×(x-15).
<h3>Definition of equation</h3>
An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.
<h3>Total cost in this case</h3>
Being "x" the price of the shoes, and knowing that:
- you apply a discount of $15 first → x -15
- you apply a discount of 20% through a second discount (
- (applied on the first discount already made) → 20%×(x-15) → 0.20×(x-15)
the equation in this case is:
<u><em>Total cost= 0.20×(x-15)</em></u>
Finally, the total cost of the shoes is 0.20×(x-15).

Answer:
x = 127°
Step-by-step explanation:
Let A, B and C be the three angles of a quadrilateral such that they are 55, 73, 105 respectively.
We know that, the sum of angles of a quadrilateral is equal to 360°. Let fourth angle be x.
55+73+105+x = 360
233+x=360
x = 360-233
x = 127°
So, the fourth angle is equal to 127°.
Answer:
The result to v(-2) taking into account the given equation is:
Step-by-step explanation:
To obtain the result to v(-2), you must understand that v(-2) means the number of views that the video had two days before Jada saw the video. Then, using the equation:
And replacing it we have:
- v(-2) = 425 * (5)^(-2)
- v(-2) = 425 * 0.04
- <u>v(-2) = 17</u>
As you can see with the calculations, <u><em>the number of views of the video two days before Jada saw it were 17</em></u>.
0.7 or 7/10. If the hundreths place is less than 5 you keep the tenths place as it is. If it is 5 or greater you round up and have the tenths place be one number higher. In this case you keep .7 because the hundreths place is lower than 5. Hoped this helped!
