Use the substitution method to solve the system of equations. Choose the correct ordered pair.
x+ 3y = 10
y= x + 2
A. (-2,4)
B. (1,3)
C. (7,1)
D. (2,4)

B. (1 , 3 )

Step-by-step explanation:

Step 1 Rearrange.

Step 2 : Multiply equation 1 by the coefficient of x in equation 2

Step 2 : Multiply equation 1 by the coefficient of x in equation 2Multiply equation 2 by the coefficient of x in equation 1

Step 3 : Subtract equation 4 from equation 3 and solve for y

Substitute the value for y in to equation 1. or equation 2 and solve for x .

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
