(5)(6)(8) = 240
240 blocks in one box.
(240)(3) = 720
720 blocks in three boxes
Add 13 to both sides
13 = 2x + 15x
Simplify right side
13 = 17x
Divide through by 17
13/17 = x
Well you're gonna wanna start at -13 for the y intercept, and then go 3 up every x, just like the equation y = 3x +13.
$74.25____16.50/2=8.25 4×16.50=66. 66+8.25=74.25
Answer:
neither; perpendicular; parallel; neither; neither
Step-by-step explanation:
parallel line is where the 2 slopes have same gradient and perpendicular means the two lines have a -1 slope when producted
