Answer:
a)8/21
b)1/9
Step-by-step explanation:
because when we divide fraction we resprocal the divisor
<span>Julia is X+5
</span><span>x+x+5=31
</span>
Now we just solve the equation
2x=31-5
x=26/2
x=13 years old (Babs' age)
and we know that julia is 5 years older this gives us the conclusion that.
13+18=31
The answer is 140 percent
Dividing (3x^2-2x) by x gives out 3x-2
