Okay so
Density= mass/volume
44800 kg/5m^3 = 8960kg/m^3
which units are preferred?
1000g/kg
1000000 cm ^3/ m^3
Answer:
C.4N+8
Step-by-step explanation:
M< 6 = m< 7 (vertical angles)
11x + 8 = <span>12x – 4
12x - 11x = 8 + 4
x = 12
so
m< 6 = </span>11x + 8
m< 6 = 11(12) + 8
m< 6 = 132 + 8
m< 6 = 140
m<4 = 180 - m<6
m<4 = 180 - 140
m<4 = 40
answer
<span>m<4 = 40</span>
