Answer:
Step-by-step explanation:
2x + 5y = 16 ------------------(1)
-5x -2y = 2 ------------------(2)
<u>Multiplying (1) by 5 </u>
5(2x+5y) = 16*5
10x+25y = 80 ----------------(3)
<u>Multiplying (2) by 2</u>
2(-5x-2y) = 2*2
-10x - 4y = 4 -----------------(4)
Adding Eq. (3) and (4)
10x + 25y -10x -4y = 80 + 4
25y - 4y = 84
21y = 84
Dividing both sides by 21
y = 4
Now, Putting y = 4 in Eq. (1)
2x + 5(4) = 16
2x + 20 = 16
2x = 20 - 16
2x = 4
Dividing both sides by 2
x = 2
Ordered Pair = (x,y) = (a,b) = (2,4)
Hope this helped!

Answer: The value of the residual for advertising dollars spent equal to $1,020 and Profit equal to $17,500 is $417
Profit=372.6+17.2 (advertising dollars)
Advertising dollars=$1,020
Predicted Profit=372.6+17.2 (1,020)→
Predicted Profit=372.6+17,544→
Predicted Profit=$17,916.6
Residual=Predicted Profit-Profit→
Residual=$17,916.6-$17,500→
Residual=$416.6
Rounded to the nearest integer:
Residual=$417
Answer: The value of the residual for advertising dollars spent equal to $1,020 and Profit equal to $17,500 is $417
Total play = 20
Nancy win = 12
Ratio would be: 12/20 = 6/10 = 3/5
So, your answer is 3/5
Answer:
approximately 26.7 million
Step-by-step explanation:
Let x be the number of cruise passengers in 2017.
6.7% increase of x gives us 28.5 m cruise passengers in 2018.
Thus, 106.7 % of x = 28.5
Multiply both sides by 100
Divide both sides by 106.7
(approximated)
Number of passengers in 2017 must have been approximately 26.7 million
