Let x be the entire portion of the money Becca needs to save to buy a new tennis racket.
So, 0.25x=$21
x=$21/0.25
x=$84
Thus, the total amount she needs to save is $84. Now, we'll deduct 25 from 84 to get the 75 percent or the remaining amount she has to save.
$84-$21=$63
The answer is $63.

Answer:
C. SUBTRACT (2x) from both sides in the bottom equation
Step-by-step explanation:
Given
![3x - 6y = -12](https://tex.z-dn.net/?f=3x%20-%206y%20%3D%20-12)
![2x + y = 12](https://tex.z-dn.net/?f=2x%20%2B%20y%20%3D%2012)
Required
The first step of a substitution method
In the second equation, notice that the coefficient of y is 1.
So, the first step is to make y the subject of the formula.
This is achieved by subtracting 2x from both sides of the equation.
![2x + y = 12](https://tex.z-dn.net/?f=2x%20%2B%20y%20%3D%2012)
![2x - 2x + y = 12 - 2x](https://tex.z-dn.net/?f=2x%20-%202x%20%2B%20y%20%3D%2012%20-%202x)
![y = 12 - 2x](https://tex.z-dn.net/?f=y%20%3D%2012%20-%202x)
<em>Hence: (c) is true</em>
The slope is 3/1.

Answer:
Its an Arithmetic progression
Step-by-step explanation:
d1= -18-(-25)= 7
d2= -11-(-18)= 7
d1 = d2
r1 = -18/25=0.72
r2 = -11/-8= 0.611
r1 isnt = r2
