Ben has a music book with 84 songs. He has learned how to play 25% of them. How many songs in the book does Ben NOT know how to play
Answer:
63
Step-by-step explanation:
This is because 25% of 84 is 21. He knows how to play 21 songs. 84-21=63.
63 is how many songs he does NOT know how to play.
Answer:
The answer is 63.
----------------------------------
24% of 84 is 21. 84 - 21 = 63.

-2(4r - 6) Mathhhhhhhhh pls
Answer: -8r+12
Step-by-step explanation:
============================================
Explanation:
The outer term -2 is multiplied by each term inside
-2 times 4r = -8r-2 times -6 = 12Then those results are added to get -8r + 12 as our final answer. We cannot combine these terms because they are not like terms.
I used the distribution property, also known as the distributive property.
That says a*(b-c) = a*b - a*c
In this case, a = -2, b = 4r, and c = 6.

Step-by-step explanation:
Can you hear me now cost function: y=0.15x+50.75
24 Hour Calls cost function: y=0.9x+24.5
Set two equations equal to each other because we want to find the time (x value) that make the cost (y-value) equal
0.15x+50.75=0.9x+24.5
0.75x=26.25
x=35mins

3(x-4)=5(x+2)
Answer:
x = -11
Step-by-step explanation:
1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis
3x-12 = 5x + 10
2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)
2x = -22
3. Divide both sides by 2
x = -11
please give me brainliest if this helped
Answer:
x=−11
Step-by-step explanation:
3(x-4)=5(x+2)
Simplify both sides of the equation:
3(x−4)=5(x+2)
(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)
3x−12=5x+10
Subtract 5x from both sides
−2x−12=10
add 12 to both sides
−2x=22
Divide by -2 both sides
x=−11
Hope this helps.

Given that the point (9,7) is on the graph of y=f(x), there is one point that must be on the graph of 2y=(f(2x)/2) + 2. What is the sum of coordinates of that point?
Answer:
Step-by-step explanation:
jjjjj
The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function
The sum of the coordinates of the point is 7.25
The reason the above values are correct is as follows;
The given parameter is;
The point (9, 7) is on the graph y = f(x)
Required:
A point on the graph, 2·y = (f(2·x)/2) + 2
Solution:
Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;
f(2·x) = f(2 × 9/2) = f(9) = 7
Therefore;
2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5
y = 5.5/2 = 2.75
y = 2.75
The coordinate of the point is (x, y) = (2.75, 9/2)
The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

Here is a balanced hanger diagram in which a circle has a mass of 3 grams and a square has a mass of 2 grams.
Which equations could represent the diagram, assuming t represents the triangles?
3c + 2s + 2t = 3c + 2s + 5t
2t + 21 = 5t + 12
3(3) + 6(2) + 2t = 2(3) + 3(2) + 5t
2t + 9 = 5t + 5
5t + 6 + 6 = 9 + 12 + 2t

Answer:
For the first one
x= About 32.02
y= About 27.58

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.
Now for the first one ]
Lets find Z first
Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.
For the second one this is easier
We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!
