<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:
-1,325 ft below sea level
Step-by-step explanation:
0(surface level) - 1,500 = -1,500
-1,500 + 525 = -975
-975 - 350 = -1,325
Answer: 15,22 and 66
Step-by-step explanation: Call the numbers a,b and c.
Their sum is 103 so a+b+c=103
The second number is 7 more than the first so b=a+7
The third number = 3 times the second so c=3b
Now replace c with 3b in the top equation, so a+b+3b=103, which becomes a+4b=103
Now replace b with a+7, so a+4(a+7)=103. This solves to give a=15
b=a+7 so b=22 and c=3b so c=66
