Answer:
Answer: upstream: 5.2= (x-y) 5
Downstream: 5.2= (x+y) 2.5
Step-by-step explanation:
Answer:
a = 6
Step-by-Step Explanation:
9 + 8a = 57
8a = 57 - 9 (subtract 9 from both sides)
8a = 48 (then divide 8 from both sides to get "a" alone)
a = 48/8
a = 6
Step-by-step explanation:
180(n-2)/n=90 ( this is the solution for the 90)
cross multiplying
180n-360=90n
180n-90n=360
90n=360
90n/90=360/90
n=4, the number of sides for the polygon with 90° is 4 sides
Solution for 100°
180(n-2)/n=100
180n-360=100n
180n-100n=360
80n=360
80n/80=360/80
n=4.5
Same applies to the rest 110°,125° ,150°,175°
A carrots top because .085 is smaller than .850 or 0.85
