What is -0.4(-5-2j)+0.3j)=-0.2(-3j+(12)]+0. 6+0.4

j = -6.8

Step-by-step explanation:

Simplify both sides of equation

−0.4(−5−2j)+0.3j=−0.2(−3j+12)+0.6+0.4

(−0.4)(−5)+(−0.4)(−2j)+0.3j=(−0.2)(−3j)+(−0.2)(12)+0.6+0.4(Distribute)

2+0.8j+0.3j=0.6j+−2.4+0.6+0.4

(0.8j+0.3j)+(2)=(0.6j)+(−2.4+0.6+0.4)(Combine Like Terms)

1.1j+2=0.6j+−1.4

1.1j+2=0.6j−1.4

Subtract 0.6j from both sides

1.1j+2−0.6j=0.6j−1.4−0.6j

0.5j+2=−1.4

Subtract 2 from both sides

0.5j+2−2=−1.4−2

0.5j=−3.4

Divide both sides by 0.5

0.5j/0.5 = -3.4/0.5

j=−6.8

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
