It’s should be D
Because if Y is the midpoint of XZ, it means XY=ZY,
or XY= half of XZ, or ZY= half of XZ.
It can also equal to 2XY=XZ, or 2ZY=XZ.
Y divides XZ into two equal parts.
Y=5x+30
X is the days
And so by plugging in x you get
y=5(5)+30
y=25+30
y=55
And so by day 5 she's running 55 minutes
But that's what I think
If 12 pairs of socks sell for $5.79, then the unit rate is 12 : 5.79. If we want to find a unit rate for one pair of socks, we need to divide 5.79 by 12:
5.79 / 12 = 0,4825
So the unit rate is 1 : 0.4825
Hope this was helpful, and if so, please mark as brainliest. ((: Thank you!
