Answer:
the answer is y= -1/2x+1/2
Step-by-step explanation:
Let x be the number of minutes for
his normal walk
On the way to the airport, for the
2/5 (or 40%) of his route, his speed is twice faster. Hence, the number of x
should be divided to 2. The rest of the route (60%) was on his normal pace. The
total minutes is 6. The equation is:
0.4(x÷2) + 0.6x = 6
<span>Solving for x, the number of
minutes for his normal walk is 7.5 minutes.</span>
Answer:
Angle A= 61°
Step-by-step explanation:
angle A+ Angle B+Angle C= 180°( Angle sum property)
∠A+57+72= 180°
∠A= 180°- 127°= 61°
