0.074n = 74
multiply both sides by 1000 to make the process simpler
74n = 74000
divide both sides by 74
n = 1000
28 + vector b = -12
vector b = -40
vector b has magnitude 40 units in the negative y direction.
Given The equation -2x(-2.8)=24, we are trying to find the value of X.
The first step is to devide both sides by 2
·-x(-2.8)=12
The next step would be to distribute.
·2.8x=12
Next we devide both Sides By 2.8 to get our final answer
·X=4.28
Although your choice answers are unclear, the answer is X=4.
