Answer:
height= 4.8cm
Step-by-step explanation:
volume= length×width× height given the volume and length and width, 288=12×5×h
288=60h
divide both sides by 60
h=4.8cm
0.15 is bigger, this is because the 0.05 in 0.15 has more value than 0.02 in 0.125, even though it has a third digit.
Answer:
3cm
Step-by-step explanation:
4x - 3y + 20 = 0....4x - 3y = -21
4x - 3y = -21.....multiply by -2
5x - 6y = -25
----------------
-8x + 6y = 42 (result of multiplying by -2)
5x - 6y = -25
---------------add
-3x = 17
x = -17/3
