Answer:
XY = (5x + 6) + (n + 10)
Step-by-step explanation:
Answer: Total cost is $1.75
Explanation:
Since we have given that
Number of postcards bought by Doug's family= 7
Cost of each postcard including tax = $0.25
Total cost is given by

Now, we want to show this in number line :
On the number line put all the number with a difference of 0.25 and run the number line seven times and we get the answer.
Each step is of length 0.25 and there are 7 jumps to reach required answer.
So, after 7 jumps we reach at 1.75 which is the required answer.
Hence total cost is $1.75
Complementary angles add up to 90 degrees. We know that AXB is 20 degrees, and AXB is complementary to CYD and FZE. So CYD and FZE are 90-20, so each angle is 70 degrees
CYD = 70 degrees
FZE = 70 degrees
CYD + FZE = 70 + 70 = 140
The average cost of a two-bedroom apartment in the city will be about $1135
Step-by-step explanation:
The regression line equation is yˆ=1.377x+137.763 where x is the cost of one-bedroom apartment.
Given that the average cost of one-bedroom apartment is $724, then using this value for x
yˆ=1.377*724+137.763 = 1134.711
This value is approximately $ 1135
