Salvatore purchased several magazines for $2 each and books for $3 each. If he spent $160 on a total of 60 books and magazines altogether, what would be the number magazines that Salvatore purchased?
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

Example
A bowl contains 10 blue and 7 red marbles. Four (4) marbles are drawn at random from the
bowl. Calculate the probability of two blue marbles drawn when sampling is done with replacement
Step-by-step explanation:
Answer. The probability of picking a blue marble from the blue urn is 2/6=1/3. The probability of picking a blue marble from the black urn is 11/15. The two events are independent so the probability of a blue marble from each urn is the product of the two separate probabilities=1/3×11/15=11/45.
If 1,200 cm2 of material is available to make a box with a square base and an open top, find the maximum volume of the box in cubic cm. For example, if the answer is 2,000 cm3 write 2000.
Answer:
4000cm³Step-by-step explanation:
Volume of the rectangular box = x²h
Surface area S = x²+4xh
x is the side length of the square base
h is the height
Given
Surface area = 1200cm²
Substitute into the formula S = x²+4xh
1200 = x²+4xh
From V = x²h
h= V/x²
1200 = x² + 4x (V/x² )
1200 = x² + 4V/x
1200x = x³ + 4V
1200x - x³ = 4V
V = 1200x/4- x³/4
V = 300x - x³/4
To maximize the volume, dV/dx = 0
dV/dx = 300 -3x²/4
0 = 300 -3x²/4
0 = 1200 - 3x²
3x² = 1200
x² = 400
x = 20cm
Since 1200 = x²+4xh
1200 = 400+80h
80h = 1200-400
80h = 800
h = 10cm
Find the volume;
Volume = 400 * 10 Volume -= 4000
Hence the maximum volume of the box in cubic cm is 4000 cm³

can you feel in the blanks
Answer:
First blank would be 25, Second blank would be 75.
Step-by-step explanation:
In order to figure out the blanks, we must figure out the original function first.
How do we do that?
-> we put in the points that we already have- in to equation:
y = ax + b
If we put the 6, 10 in to x, y , we would get :
10 = 6a + b
If we put the 12, 20 in to x, y , we would get :
20 = 12a + b
because these share the "+b" they can be subtracted.
10 = 6a + b
- 20 = 12a + b
--------------------------------------
and this would be :
-10 = -6a, a = 5/3.
we can partly complete the equation.
y = 5/3x + b, and by putting in the numbers, we can figure out that b=0.
The full equation have : y = 5/3x
now, put 15 and 45 in to the x and see what you get!
y=25, 75

What is the value of x in the solution to this system of equations?
4x+7y=85
x=2y−5
A. x = -9
B. x = 9
C. x = 8
D. x = 3
Answer:
B
Step-by-step explanation:
I used substitution to solve this system. I'll run through all of my steps below:
[tex]4x+7y=85\\x=2y-5[/tex]
I'm going to replace the 'x' values in the first equation with the entire second equation.
[tex]4(2y-5)+7y=85[/tex]
[tex]8y-20+7y=85\\15y-20=85\\15y=105\\y=7[/tex]
Now that we know what y equals, we can go back and solve for x.
[tex]x=2(7)-5\\x=14-5\\x=9[/tex]
Hope this helps!
Help I will give brainiest to the one who answers it correctly
Answer:
x = 2
Explanation:
[tex]\frac{3x-1}{5} =\frac{x+1}{3}[/tex]
First, make sure they both have common denominators ( 15 )
5 × 3 = 15 and 3 × 5 = 15
Whatever you do to the denominator you have to apply to the numerator. So, multiply the numerator and denominator of the first fraction by 3.
[tex]\frac{3*(3x-1)}{3*5}[/tex] = [tex]\frac{3(3x-1)}{15}[/tex]
Next, multiply the numerator and denominator of the second fraction by 5.
[tex]\frac{5*(x+1)}{5*3}[/tex] = [tex]\frac{5(x+1)}{15}[/tex]
Now we have: [tex]\frac{3(3x-1)}{15} =\frac{5(x+1)}{15}[/tex]
Use distributive property on the numerators of both fractions.
[tex]\frac{9x-3}{15} =\frac{5x+5}{15}[/tex]
Since the denominators are equal we can ignore them for now and find x.
9x - 3 = 5x + 5
We need to move like terms to different sides to isolate x. First, we can subtract 5x from both sides.
9x - 5x - 3 = 5x - 5x +5
4x - 3 = 5
Then, we can add 3 to both sides to cancel out the -3.
4x - 3 + 3 = 5 + 3
4x = 8
Finally, to find x we divide both sides by 4.
4x ÷ 4 = 8 ÷ 4
