A - age of Abigail
C - age of Cynthia
A = C + 8
A - 20 = 3 (C - 20)
A - 20 = 3C - 60
C + 8 - 20 = 3C - 60
C - 12 = 3C - 60 A = C + 8
2C = 48 A = 24 + 8
C = 24 years A = 32 years
Answer:
A
Step-by-step explanation:
HOEP IT HELPS I TRY MY BEST
Well if you're wanting to use substitution, you first have to end up with one term on either side of the equation. Use the second one as it's easiest.
So: x-2y=11, so find -2y as there is a -2y in the first equation.
then that becomes -2y=11-x. then sub that into equation 1, and you get:
-x+11-x=-13, which equals to -2x+11=-13, which is -2x=-24, so therefore
x=12. then chuck the x into any of the equations to find what y equals.
hope this helps!
The answer is 5 divided by 1/3
The reciprocal of 3/5 is 5/3.
To get the reciprocal of a fraction, just turn it upside down.
A fraction has a numerator, top number, and a denominator, bottom number.
To get the reciprocal of a fraction, just swap over the numerator and denominator.
If whole numbers, to get the reciprocal of whole number, just divide the whole number by 1 to make it into a fraction, then get the reciprocal of that fraction.
