Information: Suppose you are constructing a lego technic land rover defender with a total of 2573 pieces. you have already put together 253 pieces. Every minute you add 5 more pieces. My equation: y=5x+253

Question: Use your equation to determine how many total pieces you will have to put together after 45 more minutes? Show all work

So, your equation you have is y = 5x + 253.

They want to know how many total pieces you will have to put together after 45 more minutes.

So, you'll want to insert 45 in for x in the equation. Like so:

y = 5(45) + 253

Now you solve:

y = 225 + 253

y = 478

So this means you will have 478 pieces put together after another 45 minutes. There are 2573 pieces total, yes?

So, you do 2573-478

This equals = 2,095

So this means you'll still have 2,095 pieces to put together. Whew!

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
