This is the symmetric property, for you divide 9 to both sides to get x, instead of adding (addition property of equality)
So symmetric property should be your answer
Hope this helps
<em><u>Question:</u></em>
An Internet business charges a flat rate of $6.50 for shipping. If x represents the cost of the items purchased and y represents the total cost with shipping, which equation best represents the relationship between x and y?
<em><u>Answer:</u></em>
y = 6.5 + x represents the relationship between x and y
<em><u>Solution:</u></em>
Given that,
An internet charges a flat rate of $6.50 for shipping
Let "x" be the cost of items purchased
Let "y" be the total cost with shipping
Therefore,
Total cost with shipping = flat rate of 6.50 + cost of items purchased
Thus, we get,
y = 6.50 + x
y = 6.5 + x
Thus the above equation represents the relationship between x and y
Answer:
Step-by-step explanation:
(a) 25/400 X 3,875 = $242.19
(b) 50/300 X 96 = 16 lamps
(c) 175/200 X 540.72 = 473.13
(d) 100/300 X 750 = 250 boys
(e) 133/200 X240= 159.6
125/21 = 150/x
cross multiply
125x = 3150
x = 3150/125
x = 25.2 lbs....rounded up = 26 lbs <==
