Answer:-7500, 37,500
Step-by-step explanation:
The patter is multiply by negative 5 -12*5=60, 60*-5=-300... so 1500* -5=-7500, and -7500*-5=37,500
Keep in mind that a coordinate is in the form (x, y), so if you plug those values into the equation y=3x+1, you get 1=3(4)+1, simplified to 1=13, which is an untrue statement. However, I'm assuming you mean that the value of y is 4 and x is 1, which would be written as (1, 4). This would be the solution to this equation because 4=3(1)+1 is 4=4 which is a true statement.
Answer:
The mean is 9.5 and the median is 6.5.
Step-by-step explanation:
<em>To find the mean:</em>
Add all numbers given.
9+8+5+3+37+8+4+2= 76
Then divide by the amount of numbers (8).
76/8= 9.5
<em>To find the median:</em>
Re-arrange the order of the numbers from least to greatest.
2, 3, 4, 5, 8, 8, 9, 37
Count towards the middle. If there is no exact middle (like this equation), then take the two middle numbers and add them.
5+8= 13
After, divide by two since there are two numbers being added.
13/2= 6.5

Answer:
R + 5b = 300
Step-by-step explanation:
Rogers steps include a scale holding five bricks of equal weight and the scale reads 300 pounds.
We want to write an equation relating Rogers weight and the weight of the bricks to the total weight of the bricks to the total weight shown on the scale.
We have been told to use R for Rogers weight and b for the weight of a single brick.
Since Rogers is holding 5 bricks, the weight of 5 bricks will be 5b.
The sum of Rogers weight and the five bricks is equal to 300 pounds.
Therefore, the equation relating them is:
R + 5b = 300
