Answer:
13 x^2 -6x -9
Step-by-step explanation:
8x^2-4x-3+5x^2-2x-6
Combine like terms
8x^2+5x^2 -4x-2x -6-3
13 x^2 -6x -9
A)= 2/20 or 1/10
B)=16/20 or 4/5
C)=1/5
I don't know what numbers you want me to order from great to least, but a example is 1,510, 964, 478, 219, 96, 57, 35, 10, 9, 4, 3,
Answer:
Monica = 48.50
Samuel = 24.25
Kara = 17.25
Step-by-step explanation:
First you write equations as you are reading the text:
m = 2s ("Monica earned twice as much as Samuel")
s = k+7 ("Samual earned 7 more than Kara")
m = 48.50
Next, you convert these equations to solve for s and k respectively.
So, if m=2s, then s=m/2:
s = m/2 = 24.25
Likewise, if s=k+7, then k=s-7
k = s-7 = 17.25
The difference between greatest and least is 48.50 - 17.25 = 31.25
