Which equation is equivalent to –k + 0.03 + 1.01k = –2.45 – 1.81k? –100k + 3 + 101k = –245 – 181k –100k + 300 + 101k = –245 – 18
NNADVOKAT [17]
<span>The answer is -100k + 3 + 101k = -245 - 181k. In the equation –k + 0.03 + 1.01k = –2.45 – 1.81k, numbers have two decimals. So, if we multiply both of sides by 100, we will get whole numbers: 100(–k + 0.03 + 1.01k) = 100(–2.45 – 1.81k). 100 * (-k) + 100 * 0.03 + 100 * 1.01k = 100 * (-2.45) + 100 * (-1.81k). -100k + 3 + 101k = -245 - 181k.</span>
