The mass of b equals the mass of d so
24(10-x)=6(x+15)
240-24x=6x+90
30x=150
x=5
mass of d is 6(5+15)=6*20=120
mass of c=180-mas of d=180-120=60°
Answer:
first ones 11
Step-by-step explanation:
-22/-2=11
3520:20 should be correct
Without further info, like distances
check the picture
-5.8 + (-2.5) = -8.3
since both the number are negative you simply add the numbers and use the negative sign.
