1) If <em>x</em> is the number of years Naicul works, then the corporate job would earn him
49600<em>x</em> + 2000
dollars, while the teaching job would earn
50000<em>x</em>
dollars. Solve for <em>x</em> such that these two earnings are equal:
49600<em>x</em> + 2000 = 50000<em>x</em>
400<em>x</em> = 2000
<em>x</em> = 5
2) a) At a speed of 6.7 m/s, DJ would finish the race in
(100 m) / (6.7 m/s) ≈ 14.93 s
2) b) If DJ is given a headstart of <em>y</em> seconds, then Usain finishes the race in (9.58 + <em>y</em>) seconds. Solve for <em>y</em> such that this time matches DJ's time from part (a) :
14.93 s = (9.58 + <em>y</em>) s
<em>y</em> ≈ 5.35 s
Answer: B
Step-by-step explanation:
Answer:
x=120, y=70
Step-by-step explanation:
X must be 120 degrees as it is on a parallel line.
The outer+interior angles of a triangle on a straight line must be supplementary, so the second angle of the triangle is 180-120=60.
All interior angles of a triangle add up to 180 degrees: 50+60+y=180
y+110=180
y=70
Answer:
-x/5 + 6/5
hope this helps!
