<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
x is the number of minutes that will be used during a month:
C₁ = 0.24x
C₂ = 49.95 + 0.11x
So, when 1st = 2nd
0.24x = 49.95 + 0.11x
0.24x - 0.11x = 49.95
0.13x = 49.95
x = 49.95/0.13
x = 384.23 minutes
Hence, If you talk for 384.23 minutes the two plans will have the same cost.

Answer:
Adjacent - DBC and ABC, EBA and ABC
Vertical - ABC and DBE, CBD and EBA
Step-by-step explanation:
A vertical pair of angles are opposite to each other and intersect by two lines. They make an x shape.
Adjacent angles are angles that have a common vertex and side but do not overlap. They make a v shape with another line in the middle.
Answer:
abc = 8
Step-by-step explanation:
ab=2, bc=4 and ac=8
Multiply all of these together
ac = 2
Multiply by bc =4 (the left on the left and the right on the right)
ac * bc = 2*4
ab^2c =8
Multipy by ac =8 (the left on the left and the right on the right)
ab^2c *ac = 8*8
a^2 b^2 c^2 = 64
Take the square root of each side
sqrt(a^2 b^2 c^2) = ±sqrt(64)
abc = ±8
Since a,b,c are positive numbers
abc = 8
