For this case we must find an expression equivalent to:
By definition of power properties we have to meet:
So, rewriting the expression we have:
Answer:
Option B
X= weight of TV
y= weight of CD
3x+5y= 62.5
3x+ 2y= 52
You can either solve for a variable, or eliminate a variable by subtracting the second equation from the first:
3x + 5y = 62.5
-(3x+2y = 52)
0 + 3y = 10.5, so y = 10.5/3 or 3.5.
Now plug y= 3.5 back into any equation to get x:
3x + 5(3.5) = 62.5
3x + 17.5 = 62.5
3x = 45
x = 15
Always check work. Both equations should be true for x=15, y= 3.5
Answer:
Do you mean GCF?
Step-by-step explanation:
48, 60, and 96 all have a GCF of 12
12 x 4 = 48
12 x 5 = 60
12 x 8 = 96
