Answer:
x = 129.8 degrees, y = 50.2 degrees, x + y = 180
Step-by-step explanation:
Let's say you have 2 supplementary angles, x and y
So x + y = 180
if x is 79.8 degrees less than the measure of a supplementary angle, then x = y - 79.8
Putting this into our x + y = 180 equation, we get
(y - 79.8) + y = 180
2y - 79.8 = 180
2y = 180 + 79.8
2y = 259.8
y = 259.8/2 = 129.9 degrees.
so x = 129.9 - 79.6 = 50.3 degrees.
See if it worked. x = 129.9 degrees, y = 50.3 degrees, x + y = 180 so we found the correct two angles! :-)
<span>a.
</span>Let m = be the number of miles driven
Cost of NYC rentals: 525 + 0.21m
Cost of Metro Trucks: 585 + 0.13m
<span>b.
</span>525 + 0.21m = 850
0.21m = 325
M = 1,548 miles
<span>c.
</span>Initial cost for NYC rentals = $525
Initial cost for Metro Trucks = $585
<span>d.
</span>NYC rentals: 525 + 0.21 (500) = $630
Metro Trucks rentals: 585 + 0.13 (500) = $650
<span>e.
</span>525 + 0.21m = 585 + 0.13m
0.21m – 0.13m = 585 – 525
0.08m = 60
m = 750 miles
Answer:
24º
Step-by-step explanation:
C = (1/2)(56 + 116)
C = 86
4x - 10 = 86
4x = 96
x = 24
