(x + y) / (x-1 + y-1) = (x + y) divided by ( 1/x + 1/y)
Multiply numerator and denominator by 'xy' :
xy (x + y) / (y + x)
Then the whole thing falls apart, and we're left with:
xy2/3
1/3 + 3/5 + 7/10 = 49/30 or 119/30
It should be negative 1 over z.
a = 1/2
Seven.
2/3
1/3 + 3/5 + 7/10 = 49/30 or 119/30
It should be negative 1 over z.
a = 1/2
11+(7-3)2=
4 over 7.
Seven.
it equals negative 1/8
-3 + -12 = -15
Step 1: Ignore the signs, just simplify the fraction.Step 2: Count the number of negative (minus) signs. If there is one, then the answer is negative, otherwise it is positive.Step 2 can also be stated thus:-/- or +/+ = plus-/+ or +/- = minusSo, -12/412/4 = 3 and there is only 1 negative sign so the answer is negative.Answer: -3.Hope that explains it.
it is negative 4.25
Negative R.
