Complete the following problems.
Amy has $50 in her lunch account. Amy spends $3 a day for lunch. Amy's mother receives a notification when Amy's
account balance reaches $5 or lower. How many lunches can Amy purchase until her mother receives a notification? And what is the equation in slope intercept form
Answer:
Amy can purchase up to 14 lunches until her mother receives the notification. When she has the 15th lunch, the notification will be sent.
Step-by-step explanation:
The balance Amy has in her lunch account is a function of the number of lunches she has consumed.
The initial balance is $50 and it decreases by $3 for every lunch Amy has. Thus, the function that models the balance in her lunch account is:
[tex]B(x)=50-3x[/tex]
Where x is the number of lunches.
Her mother receives a notification when the balance goes at $5 or lower, thus the condition that triggers the notification is:
[tex]B(x) \le 5[/tex]
Or, equivalently:
[tex]50-3x\le 5[/tex]
Subtracting 50:
[tex]-3x\le 5-50[/tex]
[tex]-3x\le -45[/tex]
Multiplying by -1 (and flipping the sign):
[tex]3x\ge 45[/tex]
Solving:
[tex]x\ge45/3[/tex]
[tex]x\ge 15[/tex]
Amy can purchase up to 14 lunches until her mother receives the notification. When she has the 15th lunch, the notification will be sent.
Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 – 0.2x = 9.1 9.1 – 10 = 0.2x To prepare for his mountain biking trip, Rhyan bought four tire patches. Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining. Which equations could you use to find the price of one tire patch? Select all that apply. 4x – 1.9 = 22.2 4x – 22.2 = 1.9 4x + 1.9 = 22.2 4x + 22.2 = –1.9 22.2 – 4x = 1.9
Given:
Different equations are given.
Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.
To find:
The equation which gives a different value of x than the other three.
To find the equations that could you use to find the price of one tire patch.
Solution:
In option A,
[tex]9.1 = -0.2x + 10[/tex]
[tex]0.2x= 10-9.1[/tex]
[tex]0.2x= 0.9[/tex]
Divide both sides by 0.2.
[tex]x=\dfrac{0.9}{0.2}[/tex]
[tex]x=4.5[/tex]
Similarly,
In option B,
[tex]10 = 9.1 + 0.2x[/tex]
[tex]0.9= 0.2x[/tex]
[tex]4.5=x[/tex]
In option C,
[tex]10-0.2x = 9.1[/tex]
[tex]-0.2x = -0.9[/tex]
[tex]x = 4.5[/tex]
In option D,
[tex]9.1 – 10 = 0.2x[/tex]
[tex]-0.9 = 0.2x[/tex]
[tex]-4.5 = x[/tex]
Since option D has difference solution, therefore the correct option is D.
Let price of one tire patch be x.
So, price of 4 tire patches = 4x
Remaining amount in Rhyan's gift card = $1.90
Total amount = $22.20
Price of 4 tire patches + Remaining amount in gift card = Total amount
[tex]4x+1.9=22.2[/tex]
It can be written as
[tex]4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9[/tex]
Therefore, the correct options are C and E.
Answer:
c and e the last and second to last one

(05.01)Which statement best describes the area of the triangle shown below?
A coordinate grid is shown with a triangle. The base is 4 units, and the height is 4 units.
It is one-half the area of a rectangle of length 4 units and width 2 units.
It is twice the area of a rectangle of length 4 units and width 2 units.
It is one-half the area of a square of side length 4 units.
It is twice the area of a square of side length 4 units.
The answer is B. It is one-half the area of a square of side length 4 units.
3. Diego made the shape on the left, and Elena made the shape on the right. Each shape
uses 5 circles
Select all the true statements.
A. The smallest circle in Diego's design is congruent to the smallest circle in Elena's
design.
B. Diego's design is congruent to Elena's design
C. Elena's design is a translation of Diego's design
The two circle designs are missing, so i have attached it.
Answer:
Options A & B are true.
Step-by-step explanation:
Congruent circles are basically identical. This means that they have the same radius and diameter but different centres.
Now, from the attached image, we see that the smallest circle in diogo's design has diameter of 2 units & radius of 1 unit while the one in Elena's design also has exactly the same measurement. Thus, we can conclude the smallest circle in diogo's design which is the first one is congruent to the smallest circle in the second design for Elena.
So option A is correct.
Looking carefully at both designs, we can observe that one is concentric while the other is eccentric. However, all the similar sized circles have the same radius & diameter. Thus, we can still say that both designs are congruent. So option B is correct.
In transformations, a translation is when all the points in a an object are made to move up or down in a state straight line in that same direction. However, the objects shape and size remains the exactly the same.
In this case, it's not so because the circle changed from concentric circles to eccentric circles. So this option C is not correct.
Which of the following is the best example of a system of equations that should be solved by the elimination method?
Question 2 options:
8x + 3y = 2
5x + 8y = -11
2x - 4y = -16
y = 5x + 13
-8x - 9y = -17
16x - 4y = 12
12x + 7y = -17
9x + 11y = -7
Answer:the answer -8x-9y=-17
16x-4y=12
Step-by-step explanation:
divide 16x-4y=12 with 2
8x-2y=12
Then add the equations
-8x-9y=-17
8x-2y=12
0-11y=-23
You can’t do this with the other equations provided.
24. Janet and Jack are walking in a two-day event to raise money for charity.
Janet asks a friend for a $7.50 donation, plus $0.10 for each mile she
walks. Jack asks a friend for a $5.50 donation, plus $0.15 for each mile
he walks. At how many miles of walking would Janet and Jack collect the
same amount of money?
Answer:
40 miles walk
Step-by-step explanation:
Let the miles walked by both of them be x at which money collected by same
for Janet
Fixed donation asked = $7.50
money asked for walking 1 mile = $0.10
money made by Janet if he walks x miles = x*$0.10 = $0.10x
Total money collected by Janet = Fixed donation asked + money made by Janet if he walks x miles
Total money collected by Janet =7.50 + 0.10x
For Jack
Fixed donation asked = $5.50
money asked for walking 1 mile = $0.15
money made by Janet if he walks x miles = x*$0.15 = $0.15x
Total money collected by Jack = Fixed donation asked + money made by Jack if he walks x miles
Total money collected by Jack =5.50 + 0.15x
we have to find miles at which money collected by both of them be same
and we have decided that it it as x mile walk then
Total money collected by Janet = Total money collected by Jack
7.50 + 0.10x = 5.50 + 0.15x
=> 7.50 - 5.50 = 0.15x - 0.10x
=> 2 = 0.05x
=> x = 2/0.05 = 40
Thus, at 40 miles walk money collected by both of them will be same

How long will I have to wait until I save enough money for it? 385.49 + 770.98 < 1,541.72. (It's in Russian dollar so lemme translate) 385.49 = 5 US dollar) 770.98 = 10 US dollar) 1,541.72 = 20 US dollar)
Answer:
1.5 weeks

[tex]Game\ Cost = 1541.72[/tex]
Required
Determine the time taken to save up
Represent the time with t
The relationship between the given parameters can be expressed as:
