Answer:
45 marbles
Step-by-step explanation:
Using the information provided, we can form the equation x/5 - 2 = 7
Step 1: Add two on both sides of the equation x/5 - 2 = 7
Step 2: Multiply both sides of the equation by 5, to cancel out x. x/5=9
Step 3: Lastly, you get that x=45 marbles
Answer: So the sum of all of the measures of the interior angles of a 16-sided polygon is 2520 degrees.
In this question, you are only able to cancel out the (x + 5). The others are unable to be cancelled.
Answer:
y=42
Step-by-step explanation:
y+48+90=180
y=180-138
y=42
<span>Since one standard deviation is 20 luggages, 3 standard deviations above the mean is 3*20=60 luggages above the mean of 380 luggages, so 60+380 gives the answer C, 440.</span>
