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.

As long as both numbers are being multiplied by the same quantity, you will always end up with the same number.

Answer:

ez

Step-by-step explanation:

For a all you have to do is multiply by 3 so the answer would be -15

For b all you have to do is subtract 12 then divide by -1 so the answer would be -0.5

for c all you have to do is divide by -10 so the answer would be -0.1/-10 or 0.1/10

Answer:

12 miles

Step-by-step explanation:

mph = mile per hour

So if they travel 4 miles per hour, 4(3) = 12, they will travel 12 miles by 3 hours

Answer:

dude that's 12

Step-by-step explanation:

just multiply 4 mph times 3 hr

Step-by-step explanation:

Answer:

For the first one

x= About 32.02

y= About 27.58

z= About 55.16

For the second one

x= 6

y= 12

z= about 16.97

Step-by-step explanation:

Their all really simple

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!

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

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
