Answer:
b = -5
Step-by-step explanation:
So we know
3<em>a</em> = -9
Divide 3 on both sides
<em>a</em> = -3
Plug <em>a</em> in to the other equation
-3b = 15
divide -3 on both sides
b = -5
COS(64°) = 3.2/x
multiply x to both sides to get COS(64°)x = 3.2
to get x by itself, divide 3.2 by COS(64°)
x = 3.2/COS(64°)
x=7.3
Answer:
To divide one fraction by another one, flip numerator and denominator of the second one, and then multiply the two fractions. The flipped-over fraction is called the multiplicative inverse or reciprocal.
