If you can purchase 4 books $18 Then how many can you buy with $27?
Answers
Answer:
6
Step-by-step explanation:
if you divide 18 by 4 you get 4.5, and if you divide 27 by 4.5 then you get six. hope this is right :/
Answer: 6 books
Work: Okay, The first thing I did was find out how much one book costs. To find that out, I divided $18/4, and the answer is $4.50 per book. Now, we add $4.50 until it's $27. I did that, and it was just 2 more books. (4.50 + 4.50 is $9, so add nine dollars to $18, and that would be $27. Then, divide 27/4.5, and you get 6, meaning the 6 books)

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

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
Answers
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 :)

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.
Answers
[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]

Answers
-4n + 9 = -4n + 9
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
