Answer:
s₁ = 2 m/s
Step-by-step explanation:
given,
distance between Melissa and friend = 3 mile
walking speed = s₁
bike speed = s₂
total time of the trip = 2 hour
given,
s₂ = s₁ + 4
2(s₁ +4)s₁ = 3 (s₁ + s₁ + 4)
2 s₁² + 8 s₁ = 6 s₁ + 12
s₁² + s₁ - 6 = 0
s₁² + 3 s₁ - 2 s₁ - 6 = 0
(s₁ + 3) (s₁ -2) = 0
s₁ = -3 , 2
s₁ = 2 m/s
walking speed of the Melissa is s₁ = 2 m/s
The third table would be your answer.
I know this because I turned both equations shown into graph form, this allowed me to see what the x-values of 1, 2, and 3 would have for y-values. My graph of both equations is shown in the picture below. (Green is f(x) = x + 4 and purple is g(x) = -2f(x))
Sum of interior hexagon = 720
m<D = 720 - (100+115+105+130+95)
m<D = 720 -545
m<D = 175
answer
D. 175
Answer:
A) measure each side up
Step-by-step explanation:
This is how you work out perimeter,
The length times the width would be the area
And 3.142 (π) time diameter is the circumference of a circle
