This is an arithmetic series with common difference 6
S13 = (13/2)[2*-5 + (13-1)*6)] = 403
Answer: It will move up 5 spaces on the y-axis.
Step-by-step explanation: y=mx+b where b is the y-intercept (where it will be on the y-axis). In the 1st one it doesn’t have a b so there is no y-intercept so it will pass through point (0,0). In the 2nd one since your adding 5 it will now pass through point (0,5). Because it shifted up 5 on the y-axis.
Answer: the commission that she earns for selling each suit is $13
the commission that she earns for selling each pair of shoes is $8
Step-by-step explanation:
Let x represent the commission that she earns for selling each suit.
Let y represent the commission that she earns for selling each pair of shoes.
One week, she earned $47 in commission for selling 3 suits and a pair of shoes. It means that
3x + y = 47 - - - - - - - - - - 1
The next week, she earned $107 in commission for selling 7 suits and 2 pairs of shoes. It means that
7x + 2y = 107 - - - - -- - - - -2
Multiplying equation 1 by 2 and equation 2 by 1, it becomes
6x + 2y = 94
7x + 2y = 107
-x = -13
x = 13
Substituting x = -13 ,into equation 1, it becomes
3×13 + y = 47
39 +y = 47
y = 47 - 39 =
y = 8

Answer:
60%, 0.62, 0.625
Step-by-step explanation:
Step 1: Convert 5/8 to decimal form.
In order to convert a fraction to a decimal, we divide the numerator (top) by the denominator (bottom). By dividing 5 by 8, we can get the fraction 5/8 in decimal form, which is 0.625
Step 2: Convert 60% to decimal form.
In order to convert a percentage to a decimal, all we have to do is move the percentage's decimal point two spots to the left. Since 60% shows us no decimal point, we can assume that it comes directly after the 0, or 60.0%. After moving the decimal point two spaces to the left, we find that 60% = 0.60 in decimal form.
Step 3: Compare the numbers.
Since 0.62 is already in decimal form, we don't need to make any changes. This means that we can compare the numbers we just found as well as 0.62. Since our numbers would be 0.625 (5/8), 0.60 (60%), and 0.62, from least to greatest we would get 60%, 0.62, 0.625
