Answer:
Step-by-step explanation:
for x, then, 7 = (x1+5) /2
14 = x1 + 5
9 = x1
for y, then, 4 = (y1+7) /2
8 = y1 + 7
1 = y1
S = (9,1)
I think its like this
each row has 6 white tiles
8 rows = 48 tiles
48 - 6 = 42
42 x 8 = 336
so 8 rows = 6 white tiles and 42 purple tiles to make 48 tiles so she will need 336 more tiles to make each 8 rows have 48 tiles
hope this helps : )
$425 - $25 = $400
$400/ 2 (the two people)= $200
Seiji made $225 because it said he made $25 more
and Gavin made $200
