2x+38=50
2x+38-38=50 -38
2x =12
2x/2 =12/2
x=6
So work =time times rate or W=TR
so T=m-k
W=(m-k)R
if you want just m-k then m-k is the answer
Answer:
B
Step-by-step explanation:
Answer:
cos(∅) = 3/5
Step-by-step explanation:
cos(∅) = adjacent/hypotenuse
We don't know what the hypotenuse is so we gotta use Pythagorean theorem to find it.
a² + b² = c²
4² + 3² = c²
√(4² + 3²) = c
c = 5 , this is our hypotenus
cos(∅) = adjacent/hypotenuse
cos(∅) = 3/5
