Answer:y=-1/2
Step-by-step explanation:
125=(1/25)^(y-1)
5^3=(5^(-2))^(y-1)
5^3=5^(-2(y-1))
The same base eliminate each other we then have
3=-2(y-1)
3=-2y+2
Collect like terms
2y=2-3
2y=-1
Divide both sides by 2
2y/2=-1/2
y=-1/2
<em>THE ANSWER IS 110 m</em>
<em>Workers had repaired 3/4 of the road</em>
<em> it means3/4×440 is been repaired</em>
<em>length of repaired road is 3×110 = 330m</em>
<em>length of unrepaired road = Length of to road - length of repaired road</em>
<em>i.e. = 440-330 = 110m</em>
