You need to get x alone. So first you bring the 13 over and it becomes negative because it switches signs when switching sides
13x=104-13
13x=91
The you have to divide by 13 since you are multiplying on the other side
X=91/13
Your final answer should be
X=7
Okay. So, we're looking for the percentage of Celina's running speed as her walking speed. Her running sped is 8 mph and her walking speed is 4mph. All we have to do is 4/8 = x/100. You put change/original and x/100, because we're looking for the percent of change from running speed to walking speed. Cross multiply the values to get 400 = 8x. Divide each side by 8 to isolate the "x". 400/8 is 50. x = 50. Celina's walking speed is 50% of her running speed. The answer is B: 50%.
Answer:
63:147
Step-by-step explanation:
Because 3*21= 63 and 7*21= 147
The common difference is 2
