How many 2.5 inches by 6 inch tiles will fit on a black splash that is 2.5 feet tall and 8 feet long

192

Step-by-step explanation:

First you need to figure out how many inches long the top and side are:

8*12 = 96

2.5*12 = 30

Then you figure out how many tiles you can fit on one side. so what I did was divided 96 by 6 because they are both the long sides and I need to know how many of the tiles can fit on the long side.

96/6 = 16

30/2.5 = 12

Know you know that 16 tiles can fit the long ways and 12 can fit the short way so then you multiply them because you want to know how much can cover an area.

16*12 = 192

there you go hope this helped. its a little confusing or if you have questions just ask :)

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
