Answer:
560 cubes
Step-by-step explanation:
Volume of prism: lwh, 7*4*2.5, 70cm!
Volume of cubes: lwh, 0.5*0.5*0.5, 0.125cm!
70cm/0.125cm=560 cubes.
<span>2(3 - x) = -16
3 - x = -16/2
3 - x = -8
-x = -8 - 3
-x = - 11
x = 11</span>
x = 2 and y= 1
y = 3x-5
1= 3 x 2 - 5
1= 6-5
1=1
6x+3y=15
6 x 2 + 3 x 1 = 15
12+3=15
15=15
