Answer:
10 weeks.
Step-by-step explanation:
Let w represent number of weeks.
We have been given that Kaitlyn saves $6 each week. So the amount saved in w weeks would be dollars.
Since Kaitlyn wants to save $6. This means that amount saved in w weeks should be equal to $60.
Let us solve for w by dividing both sides by 6.
Therefore, Kaitlyn must continue to save for 10 weeks to have a total of $60.
Answer:

Hence, at least 16 calls must be made.
Answer:
x - y + 6 = 0
Step-by-step explanation:
In normal form of a straight line, the equation is given by
where p is the perpendicular distance of the line from the origin and is the angle between the perpendicular line and the positive direction of the x-axis.
Here, in our case and
Degree,
Therefore, the normal form of the straight line equation is
⇒
⇒ {Since, Cos (180 - Ф) = - Cos Ф and Sin (180 - Ф) = Sin Ф}
⇒
⇒ - x + y = 3√2 × √2 = 6
⇒ x - y + 6 = 0
So, the standard form of the equation is x - y + 6 = 0. (Answer)
Answer:
The hotel bill in the first city before tax would be $ 650
Step-by-step explanation:
Let x be the hotel charges ( in dollars ) before tax in the first city,
∵ Hotel charges before tax in the second city were $1500 lower than in the first.
So, the hotel charges in second city = ( x - 1500 ) dollars,
Now, percentage of tax in,
First city = 8%
Second city = 10%,
So, the total tax in both city = 8% of x + 10% of (x-1500)
According to the question,
Hence, the hotel bill in the first city before tax would be $ 650.
