Answer:
( 4, 1 )
Step-by-step explanation:
midpoint formula: (x1 + x2/ 2, y1 + y2/ 2)
(9-1/ 2, -6+8/ 2) -> (4,1)
Answer:
26
Step-by-step explanation:
Subtract
Answer:
go right 5 from (0,0) then up 5 from (5,0)
Step-by-step explanation:
B
step 1 is to distribute the bracket by 
=
× 15x -
× 30y + 10x
= 6x - 12y + 10x ← step 1
Ratios shall be used
Selling 3x as many tie-dyed as silk is the equivalent of ratio 3:1 (Three tie dies for 1 silk)
Add up the total numbers in the ratio (By that I mean 3 + 1) to get 4
Divide the total number sold by 4 to get 42
Multiply 42 by 3 (The number of tie dyes sold in the ratio) to get 126
126 tie-dyed shirts were sold
