If we are eliminating x, we would multiply the 2nd equation by -5
5x + 18y = 23
x + 3y = 2....multiply by -5
-----------------
5x + 18y = 23
-5x - 15y = - 10 (result of multiplying by -5)
----------------add
0 + 3y = 13.....bye-bye x :)

I hope this will help you buddy
The angle bisector, median, and altitude are all the same things in an isosceles triangle.
That means that the legs of the smaller triangles created by the altitude are 4 root 2.
By special properties of an right triangle, the hypotenuse is 8.
Since the legs of the original right triangle are congruent, the area of the original triangle is 8*8/2.
Now we just simplify:
8*8/2=64/2=32
The 16th term is: 53
Further explanation:
We have to find the general formula first
The general form is:
The 16th term is: 53

Answer:
The volume of the shoe box is 420 cubic inch
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a righ rectangular prism
Given data
Length of prism l= 12inches
Width of prism w= 7 inches
Height of prism h= 5 inches
We know that the volume of a rectangular prism is expressed as
Volume =l*w*h
Volume = 12*7*5= 420in³
