Rearrange the equation so r is the independent variable.
q-10= 6(r+1)
q=

r = ( q -16)/6

Step-by-step explanation:

In order to rearrange the equation so that r is the independent variable is the same thing as making r the subject of the formula from the given expression

q-10= 6(r+1)

we say,

q - 10 = 6r + 6 ( by using 6 to open the bracket)

we are going to collect the like terms

q- 6r = 6 + 10

q- 6r = 16

q = 16 + 6r

q-16 = 6r

divide both sides by the coefficient of r which is 6

(q-16)/6 = 6r/6

r = ( q -16)/6

q = 6r + 16

I got this from Khan Academy.

Hope this helps! :)

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 "

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
