Shari and Ana are playing games at an arcade. Shari has $37.50 and is playing $0.50 games. Ana has $42.75 and is playing $0.75 games. Sandor wants to know when Shari and Ana will have the same amount of money remaining. So he wrote and solved this equation.
Let x = number of games played.
Equation: 37.50 – .5x = 42.75 – .75x
Step 1: 37.50 – 1.25x = 42.75
Step 2: – 1.25x = 5.25
Step 3: – 4.2 = x
Sandor knows his answer is incorrect because a negative number of games cannot be played. What was Sandor’s mistake?
The variable x should represent the amount of money left.
The equation should have sums on both sides.
In step 1, he should have added .75x to both sides.
In step 3, he should have added 1.25x to both sides.
[tex]37.50-0.5x=42.75-0.75x\\37.50-0.5x+0.75x=42.75\\37.50-0.25x=42.75\\0.25x=42.75-37.50\\0.25x=42.75-37.50\\0.25x=5.25\\x=\frac{5.25}{0.25} \\x=21\\\\x=21 grams[/tex]

The ages of Aman and Arun are in the ratio 5:7. Four years later the sum of their ages will be 56 years. What are their present ages
Answer:
Aman's age = 20, Arun's age = 28
Step-by-step explanation:
Let [tex]x[/tex] = Aman's age
Let [tex]y[/tex] = Arun's age
- - - -
[tex]x+4+y+4=56[/tex] (Sum of their age is 56 after 4 years in the future)
[tex]x+y+8=56[/tex]
[tex]x+y=48[/tex]
[tex]\frac{x}{y} = \frac{5}{7}[/tex] (Ages are in the ratio 5:7)
[tex]x=\frac{5}{7}y[/tex]
Now, we can use substitution to find for Arun's age:
[tex]x+y=48[/tex]
[tex]\frac{5}{7}y+y=48[/tex]
[tex]\frac{12}{7}y=48[/tex]
[tex]y=28[/tex]
∴ Arun is [tex]28[/tex]
To find for Aman's age, we can use substitution:
[tex]x+y=48[/tex]
[tex]x+28=48[/tex]
[tex]x=20[/tex]
∴ Aman is 20
Hope this helps :)

Is y=12 x+3 a proportional relationship
Answer:
no
Step-by-step explanation:
A proportional relationship is of the form
y = kx
This is equation is of the form
y = kx+b
They are not the same so it is not a proportional relationship

9√2 is squared first.
so its 162.
now according to Pythagoras theorem,
x2+x2=162
2x^2= 162
x^2= 162÷2
x^2= 81
x= √81
x=9
in a right angled triangle, (height)^2 + (base)^2 = (hypotenuse)^2
here we have , height as X and base as X too , so; x^2 + x^2 = (9√2)^2
2(X)^2 = 162
x^2 = 162/2
X^2 = 81
X = √81 = 9

What is the slope-intercept equation of the line below?
A. y = -4+3
B. y = 4x+3
C. y = 5/4x+3
D. y=-5/4x+3
Answer:
SInce you have not posted the full question so I will tell you the answer through the question you have just posted.
A. slope-intercept is 0
B. slope-intercept is 4
C. sope-intercept is 5/4
D. slope-intercept is -5/4
Step-by-step explanation:
To find the slope intercept easily by the following equations. just write the value besides x.
Equation is y = mx + c
m is the slope and c is the constant.
-4n + 9 = -2 (2n -1) +7
Answer:
infinite number of solutions
Step-by-step explanation:
Given
- 4n + 9 = - 2(2n - 1) + 7 ← distribute and simplify right side
- 4n + 9 = - 4n + 2 + 7
- 4n + 9 = - 4n + 9
Since both sides are equal then any value of n makes the equation true.
That is there are an infinite number of solutions

Is (3,8) a solution to the system? Explain.
Answer:
It's the solution for the first one, but not the second one
Step-by-step explanation:
(3,8) (x,y)
The first one works, because it does equal 20
4*3= 12+8= 20
The second one does not work, because it equals 7 and not 8
3*3= 9-2= 7
