Answer:
Step-by-step explanation:
Let c represent the total cost of booking either Uber or Lyft for x miles.
Let m represent the number of miles ridden with either Uber or Lyft.
Uber charges $0.80 per mile and a booking fee of $2.30. This means that the total cost of riding with Uber for m miles would be
c = 2.30 + 0.8m - - - - - - - - - -1
Lyft charges $1.07 per mile with no booking fee. This means that the total cost of riding with Lyft for m miles would be
c = 1.07m - - - - - - - - - -2
Equation 1 and equation 2 are the system of equations that bests models this situation
Answer:
The nearest whole yard would be 1 or 1.0 because 8 is larger than 5 so you would round up giving you 1
Answer:
The volume of the triangular prism is 5676.16 cm³
Step-by-step explanation:
The area of the triangular base A = bh/2 where b = base = 28 cm and h = height = 22.4 cm.
Now, the volume of the triangular prism, V = area of triangular base, A × height of prism, h'
V = Ah' where h = height of prism = 18.1 cm
So, V = bhh'/2
Substituting the values of the variables into the equation for V, we have
V = bhh'/2
V = 28 cm × 22.4 cm × 18.1 cm/2
V = 14 cm × 22.4 cm × 18.1 cm
V = 5676.16 cm³
So, the volume of the triangular prism is 5676.16 cm³
X=-4y+2
3(-4y+2)+2y=11
-12y+6+2y=11
-10y+6=11
-6=-6
-10y=5
y=-1/2
3x+2(-1/2)=11
3x-1=11
+1=+1
3x=12
x=4
Solution:(-1/2,4)
