Solution can be found in attachment.
the system has no solution.
Option C is correct.
Step-by-step explanation:
We need to solve the system of equations by substitution

Putting value of x from eq(2) into eq(1)

As as 0≠4is not true, we cannot find the value of y so the system has no solution.
Option C is correct.

Answer:
<B = 108 degrees
Step-by-step explanation:
<A = <B <u><em> (Alternate Angles are congruent)</em></u>
So,
6x+18 = x+93
=> 6x-x = 93-18
=> 5x = 75
<em>Dividing both sides by 5</em>
=> x = 15
Now,
<B = x+93
=> <B = 15+93
=> <B = 108 degrees
D) because only 4 is the common factor in the equation.
To find the lateral surface area of a pyramid, you can find the area of each triangle, A = 1/2bh or A = 1/2lw, then multiply by the number of triangles, which would be based on the number of sides of the base; or you can take half the perimeter and multiply by the slant height.
