Answer:
the number of magazines purchased is 20
Step-by-step explanation:
As it is mentioned in the question that there is a total of 60 books + magazine altogether
Here we used the following equations
Let us assume the number of magazines be x
ANd, the number of books be y
x + y = 60 .............(1)
2x+ 3y = $160 ..........(2)
Now multiply with 2 in the equation 2
Then it comes
2x + 2y = 120
2x + 3y = 160
Solve these equations
y = 40
Now the x value is
x + 40 = 60
x = 20
Hence, the number of magazines purchased is 20

How to find the square root of 40 by long division method
Here we will show you how to calculate the square root of 40 using the long division method with one decimal place accuracy. This is the lost art of how they calculated the square root of 40 by hand before modern technology was invented.
Step 1)
Set up 40 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:
40 00
Step 2)
Starting with the first set: the largest perfect square less than or equal to 40 is 36, and the square root of 36 is 6. Therefore, put 6 on top and 36 at the bottom like this:
6
40 00
36
Step 3)
Calculate 40 minus 36 and put the difference below. Then move down the next set of numbers.
6
40 00
36
4 00
Step 4)
Double the number in green on top: 6 × 2 = 12. Then, use 12 and the bottom number to make this problem:
12? × ? ≤ 400
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 3. Now, enter 3 on top:
6 3
40 00
36
4 00
That's it! The answer is on top. The square root of 40 with one digit decimal accuracy is 6.3.

The fair charges an entrance fee of $10, and each ride costs $2. 1) Write an equation relating number of rides r, to the total cost of attending the fair C. 2) What is the dependent variable? 3) What is the independent variable?
Answer:
1) y = $10 + $2x
2) independent variable is the number of rides (x)
3) dependent variable in this equation is the total cost (y)
Step-by-step explanation:
In this scenario, we have two fixed values and two variables which would be the number of rides (x) and the total cost (y). Therefore, since the entrance fee is a fixed value it is added to the cost of each ride which is multiplied by the number of rides represented by the variable (x).
y = $10 + $2x
In this equation, the independent variable is the number of rides (x) because it is a separate value from the equation and does not depend on any other value. The dependent variable in this equation is the total cost (y) which depends on the number of rides that the individual goes on in order to have its own value.

Which expression means the same as "subtract 3 from 7 and then multiply
by 4"?
Answer:
(7-3)x4
Step-by-step explanation:
Youre subtracting 3 from 7 so that means that 7 is first because your subtracting 3 and seven is the greater number, it says to then multiply by 4 so that means that you have to put parenthesis around 7-3 because you need to do them first. I hope this makes sense and answers your question! :)

Factor the expression using the GCF. 76d-24=
Answer:
Factoring the expression [tex]76d-24[/tex] using the GCF we get [tex]\mathbf{4(19d-6)}[/tex]
Step-by-step explanation:
We need to factor the expression using the GCF : [tex]76d-24[/tex]
GCF stands for greatest common divisor.
We need to find the greatest number that is divisible by both terms.
The greatest number that is divisible by both terms is 4
So, Now factoring the term:
[tex]76d-24\\=4(19d-6)[/tex]
So, factoring the expression [tex]76d-24[/tex] using the GCF we get [tex]\mathbf{4(19d-6)}[/tex]

Which of the following could be the equation of a line parallel to the line y = 4 ?
A- undefined
B- y=0
C- x=4
D- y=4x
Answer:
B
Step-by-step explanation:
y = 4 is a horizontal line parallel to the x- axis
A parallel line must also be horizontal with equation
y = c ( c is the value of the y- coordinates the line passes through )
The only equation in this form is
y = 0 ( the equation of the x- axis ) → B
Option B: [tex]y=0[/tex] is the equation of the line parallel to the line [tex]y=4[/tex]
The general equation of a line is [tex]y=mx+b[/tex] where, [tex]'m'[/tex] is the slope of the line and [tex]'b'[/tex] is the constant.
For a line to be parallel with the line [tex]y=4[/tex], the slope must be equals to [tex]0[/tex].
So, [tex]y=0[/tex] is the only option in which the slope is equals to zero and so, it is parallel to the line [tex]y=4[/tex].

Find the sum of the arithmetic progression 1,4,7,10,13,16 .Every third term of the above progression is removed i.e 7,16. Find the sum of the remaining terms
Answer:
The sum of the arithmetic progression is 51
The sum of the remaining terms is 28
Step-by-step explanation:
Sum of terms of an arithmetic progression
Being a1 the first term of an arithmetic progression, an its last term, and n the number of terms, the sum of all terms is calculated as:
[tex]\displaystyle S_n=\frac{a_1+a_n}{2}\cdot n[/tex]
We are given the progression:
1,4,7,10,13,16
We need to check if the list of numbers is a progression. The difference between consecutive terms must be equivalent.
Since:
4 - 1 = 3
7 - 4 = 3
10 - 7 = 3
And the rest of the differences also result in 3, the series of numbers has a common difference of 3.
The progression has the following parameters:
a1=1, an=16, n=6
Let's find the sum:
[tex]\displaystyle S_6=\frac{1+16}{2}\cdot 6[/tex]
[tex]\displaystyle S_6=\frac{17}{2}\cdot 6[/tex]
[tex]S_6=51[/tex]
The sum of the arithmetic progression is 51
If we removed the terms 7 and 16, the new sum is:
51 - 7 - 16 = 28
The sum of the remaining terms is 28
what is the equation for the line that passes through the given point and is parallel to the graph of y=2/3x+19; (-9, 4)
Answer:
Step-by-step explanation:
We're given the line
[tex]y = \frac{2}{3}(x) + 19[/tex]
The slope of the line is [tex]\frac{2}{3}[/tex]
We have to find another line with the same slope that goes through the point
[tex](-9, 4)[/tex]. We can solve this by using
[tex]y = mx + b\\y = \frac{2}{3}(x) + b\\4 = \frac{2(-9)}{3} + b\\4 = -6+ b\\b = 10\\\\y = \frac{2}{3}(x) + 10[/tex]
