The day in which Chloe would have more money than Kenzi is after 15 days.
When would Chloe have more money?The equation that represents the amount left after the purchase of Frutti Tutti and lunch is:
Amount left = amount she began with - (amount spent x number of days)
Amount that Chloe has left : $75 - $3x
Amount that Kenzi has left : $90 - $4x
The inequality that can be used to represent when Kenzi would have less money than Chloe is:
$75 - $3x > $90 - $4x
$4x - 3x > $90 - $75
x > 15

An airplane flying against the wind travels 280 miles in the same amount of time it would take the same plane to travel
420 miles with the wind. If the wind speed is a constant 70 miles per hour, how fast would the plane travel in still air?
Answers
The speed of plane in still air is 150 miles per hour.
What is speed?
Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
speed = distance/time
Let s = speed in still air
then(s-70) = ground speed against the wind
and
(s+70) = ground speed with the wind
Write a time equation; time = distance/speed
time against = time with still air
280/(s-30) = 420/(s+30)
Cross multiply
420(s-70) = 280(s+70)
420s - 29400 = 280s + 19600
420s-280s = 19600+29400
140s=49000
s = 49000/140
s = 350 mph

What is the length of AB? round your answer to the nearest hundred.
Answers
In order to calculate the length of the line AB, you use the following formula for the distance between points in the coordinate plane:
d = √((x2-x1)²-(y2-y1)²)
That is, it is only necessary to have a pair of points with coordinates (x1,y1) and (x2,y2). In this case you have two points A=(-5,-4)=(x1,y1) and B=(-3,3)=(x2,y2), then, by replacing these values into the formula for the distance you have:
d = √((3-(-3))²-(-5-4)²)
d = √((3+3)²+(-9)²)
d = √(36+81) = √(117) = 10.8166 ≈ 10.82
Hence, the length of the line AB is 10.82

What are Intersecting lines?They are referred to be intersecting lines when two or more lines in a plane cross each other. The point of intersection, which can be found on all intersecting lines, is the common point shared by the intersecting lines. The intersecting lines (two or more) always meet at a single location. Any angle can be used to intersect the intersecting lines. This angle is always larger than zero and less than 180 degrees. Vertical angles are created by two lines intersecting. With a common vertex, the vertical angles are opposite angles (which is the point of intersection). Curved lines, not straight ones, are what intersect at several points.To learn more about Intersecting Lines, refer to:

A boat can travel 16 miles against a current in the same time it can travel 40 miles with the current. The current flows at 3 mph. What is the rate of the boat in still water?
Answers
The rate of the boat when it's still in water is 7mph.
How to calculate the rate?Based on the information, one can denote that the travel times are the same. The formula to calculate the rate will be:
d1/v1 = d2/v2
where
v = rate
d = distance of miles.
This will be:
t = 16/(v - 3) = 40/(v + 3)
Cross multiply
40(v - 3) = 16(v + 3)
40v - 120 = 16v + 48
Collect like terms
40v - 16v = 48 + 120
24v = 168
Divide through by 24
24v/24 = 168/24
v = 7 mph
The rate is 7mph. This shows the concept of the calculation for rate.

Shelby is searching online for airline tickets. Two weeks ago, the cost to fly from to was $210. Now the cost is $305. What is the percent increase? What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price?
Answers
The percentage increase of the airline ticket is 45.24%
Percentage IncreaseThe concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original. An increase of 5 percent would indicate that, if you split the original value into 100 parts, that value has increased by an additional 5 parts.
Mathematically, the percentage increase of a quantity can be written as
[tex]\% increase =\frac{change in quantity}{original quantity} * 100[/tex]
Let's substitute the values given into the equation and find the percentage increase.
[tex]\% increase =\frac{change in quantity}{original quantity} * 100\\\% increase = \frac{305 - 210}{210} *100\\\% increase = 45.24\%[/tex]
The increase in percentage of the ticket price is 45.24%
If the airline charges an additional $50 with the new ticket price, the percentage increase will remain the same because assuming the baggage fees is also applicable to the old price, there won't be an change in the percentage increase.

I need help with this question causey teacher didnt teach this to us.3(5-p) - 2(5 + p) = 3(p+1). Find p
Answers
Explanations:
The given equation is:
3(5 - p) - 2(5 + p) = 3(p + 1)
Step 1: Expand all the brackets
15 - 3p - 10 - 2p = 3p + 3
Step 2: Collect like terms ( That is, let everything that has p go together)
15 - 10 - 3 = 3p + 3p + 2p ( Note that the sign changes when anything crosses the equality sign)
2 = 8p
Step 3: Divide both sides by 8
2/8 = 8p/8
1/4 = p
p = 1/4
p = 0.25
