Darin can purchase tile at a store for 0.79 per tile and rent a tile saw for $24. At another store, he can borrow the tile saw f
ankoles [38]
Let us denote the number of tiles by T.

In the first store, if Darin bought T tiles, he would need to spend:
                        0.79\times T+24 (measured in $)

In the second store, if Darin bought T tiles, he would need to spend:
                        1.19\times T (measured in $)

For the cost to be the same at both stores, it means (measured in $)
                                           1.19T=0.79T+24

Moving 0.79T over to the left hand side and changing signs:
                                            1.19T-0.79T=24
                                            0.4T=24
                                            T= \frac{24}{0.4}
                                            T=60 tiles

Let's check. If he buys 60 tiles in the first store, he spends:
                              $0.79×60 + $24 = $47.40 + $24 = $71.40

If he buys 60 tiles in the second store, he spends:
                                               $1.19×60 = $71.40

∴ Darin needs to buy 60 tiles for the cost to be the same at both stores.

Are these lines parallel, perpendicular, or neither? 3y=x+4 and 3x+y=1
REY [17]

Answer:

perpendicular

Step-by-step explanation:

3y = x + 4 in slope intercept form y = 1/3x +4/3

3x + y = 1 in slope intercept form y = -3x +1

the slopes are negative reciprocals of each other so they are perpendicular
