For this case we must make a conversion from pounds to kilograms.
By definition we have to:
1 kg equals 2.20462 pounds. Making a rule of three we have:
2.20462 pounds ---------------> 1 kg
127 pounds -----------------------> x
Where "x" represents the amount of kg.
Thus, 127 pounds represent 57.61 kilograms.
Answer:
57.61 kilograms.
Answer:
(x-10) (x+1) =0
x=10 x=-1
Step-by-step explanation:
x^2 -9x-10 =0
Factor
What two numbers multiply to -10 and add to -9
-10*1 = -10
-10+1=-9
(x-10) (x+1) =0
Using the zero product property
x-10 = 0 x+1=0
x-10+10=0+10 x+1-1=0-1
x=10 x=-1
These are the x intercepts
So set up the equations
q-12=d
25q+10d=1105
plug in q-12 as d in the second equation:
25q+10q-120=1105, then simplify:
35q=1225
q=35
since there's 12 fewer dimes, we know that there's 23 dimes and 35 quarters.
Answer:
(3b+2)(3b-2)
Step-by-step explanation: It is the correct answer because we are factoring to the prime number.
