A bricklayer is building a large base for a sign. She uses 6 blocks for the top layer and each layer requires 8 more blocks than the layer above it. The bottom layer has 102 bricks. How many layers are there in the sign base? Describe an equation-based method to answer the bricklayer question.

Describe a pictorial- or manipulative-based method to answer the bricklayer question.

step-by-step explanation:

de-gf

hj=3x+20

ji=15x-64

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
