which equation is equivalent to –k 0.03 1.01k = –2.45 – 1.81k?
-k + 0.03 + 1.01k = -2.45 - 1.81k
Multiplying through by 100, we have
-100k + 3 + 101k = -245 - 181k
Answer:
Equivalent equation 1.82k+2.48 = 0
where \(\mathbf{k=-\frac{124}{91}=-1.363}\)
Step-by-step explanation:
–k+0.03+1.01k = –2.45–1.81k
First bring all the values to the left hand side of the equation changing the signs accordingly
-k+0.03+1.01k+2.45+1.81k = 0
Bring all the k terms and non k terms together
-k+1.01k+1.81k+0.03+2.45 = 0
Solve the k terms and the non k terms
0.01k+1.81k+2.48 = 0
⇒1.82k+2.48 = 0
Take the non k term to the right hand side which will change the sign
1.82k = -2.48
Rearranging the equation we get
\(k=-\frac{2.48}{1.82}\)
Multiply numerator and denominator by 100
\(k=-\frac{248}{182}=-\frac{124}{91}=-1.363\)
k = -1.363
