Answer:
a =6
b=4
c=2
step-by-step explanation:
= 
= 
= 
No, his bpm is too high, the average heart will go about 217-227.5 in a span of 3 1/2 min, and his is about 15.75 to high, (his bpm is 68 while it should be 62-65)
Option m = 17
y = total cost of the service
m = number of miles run
y = 1.25 + 0.75 m
Equal the cost to the amount available by Henri
14 = 1.25 + 0.75m
Solve for m
m = (14 - 1.25)/0.75 = 12.75 / 0.75 = 17 miles.
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
