Answer:
Step-by-step explanation:
Since, box contains two layers of cubes and each layer has 15 cubes.
So, length = 15*1/2 in = 7.5 in,
width = 3*1/2 in = 1.5 in
height = (1/2 + 1/2) = 1 inch
Volume of box = lbh
= 7.5* 1.5 *1
= 11.25 cubic inches
Answer:
8y = - 6
Step-by-step explanation:
Given the 2 equations
x + 6y = 9 → (1)
- x + 2y = - 15 → (2)
Adding the 2 equations term by term gives
(x - x) + (6y + 2y) = (9 - 15), that is
8y = - 6

Step-by-step explanation:
2x+4= 3x-6+2
2x+4=3x-4
2x-3x+4=3x-3x-4
-x+4=-4
-x+4-4= -4-4
-x=-8
Need to multiply by -1 for x to be positive and also for -8
-1(-x)= -1(-8)
x=8
