You are remodeling your kitchen. you’ve contacted two tiling companies who gladly told you how long it took their workers to tile a floor of a similar size. jim completed half the floor in 12 hours . pete completed the other half in 10 hours. if pete can lay 25 more tiles per hour than jim, what equation would you use to find the rate that jim can lay tiles. let x represent jim’s rate

As given, let Jim's rate = x

Let Pete's rate =y

Jim completed half the floor in 12 hours so it's = 12x 

Pete completed the other half of the floor in 10 hours so its =10y

As floor area is equal so,

.............(1)

Now, given is that Pete can lay 25 more tiles per hour than Jim, this gives=

...... (2)

Putting the value of y from equation (2) in equation (1) , we get

So, the equation is :

If you want to solve it, it becomes:

Hence, Jim can lay 125 tiles and Pete can lay 25 more so 125+25=150 tiles.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
