which expression represents half of a number,n,plus 3?

Here's how to solve your equation step by step:

−21−9k=−8(6k+3)

Step 1: Simplify both sides of the equation.

−21−9k=−8(6k+3)

−21+−9k=(−8)(6k)+(−8)(3) (Distribute)

−21+−9k=−48k+−24

−9k−21=−48k−24

Step 2: Add 48k to both sides.

−9k−21+48k=−48k−24+48k

39k−21=−24

Step 3: Add 21 to both sides.

39k−21+21=−24+21

39k=−3

Step 4: Divide both sides by 39.

39k/39 = -3/39

Here's the answer: -1/13 or -0.08.

For this problem I got 1725/493 which could be converted as -3.49898...

Correct me if I'm wrong - But I believe this is right

Answer:

[tex]\boxed {x = 4}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]x - 9 = -5[/tex]

-Add both sides by [tex]9[/tex]:

[tex]x - 9 + 9 = -5 + 9[/tex]

[tex]\boxed {x = 4}[/tex]

So, the value of [tex]x[/tex] is [tex]4[/tex].

Answer:

50!!11!

Step-by-step explanation:

dividing a fraction is just like multiplying by the fraction's reciprocal~

(reciprocal is 4/3)

37.5 x 4 = 150

150 / 3 = 50

Answer:

50

Step-by-step explanation:

37 1/2 divided by 3/4 and convert to 74 divided 3/4

74/1 divided by 3/4 is

74/1 times 4/3

296/3 which equals 50

Answer: The calculation is correct.

Step-by-step explanation:

If Hernando ate 2/8 of a pizza for a dinner, the remaining pizza will be:

= 1 - 2/8

= 6/8

If he gave his 6 friends the rest of the pizza and told them to share it equally, each person will get:

= 6/8 ÷ 6

= 6/8 × 1/6

= 1/8

Each person will get 1/8 each

Since he also concluded that each person received 1/8 of the whole pizza, Hernandos calculations are correct

Because there is a negative sign before parentheses.

The sign( a) is negative When multiplied by the negative before the parentheses The sign becomes negative

Hey there!

First, let's solve this maths problem:

7a-(3+8a)

Here we should use the Distributive Property and distribute -

Wait, what? Distribute a minus? Yeah! The minus sign (in this case) is the same as -1:

7a-3-8a

Now, why did the plus sign change to the minus sign?

Because a negative times a positive is a negative.

Hope everything is clear.

The resulting speed and direction of the airplane are approximately 377.492 miles per hour and 93.413°, respectively.

In this question we must apply vectors in rectangular form to determine the absolute velocity of an airplane. which is the sum of velocity at still air ([tex]\vec v_{A/W}[/tex]) and wind velocity ([tex]\vec v_{W}[/tex]), both in miles per hour. If we know that [tex]v_{W} = 50\,\frac{mi}{h}[/tex], [tex]\theta_{W} = 40^{\circ}[/tex], [tex]v_{A/W} = 350\,\frac{mi}{h}[/tex] and [tex]\theta_{A/W} = 100^{\circ}[/tex], then resulting velocity is:

[tex]\vec v_{A} = 50\cdot (\cos 40^{\circ}, \sin 40^{\circ}) + 350\cdot (\cos 100^{\circ}, \sin 100^{\circ})[/tex]

[tex]\vec v_{A} = (-22.474, 376.822)[/tex]

Whose magnitude ([tex]v_{A}[/tex]), in miles per hour, and direction ([tex]\theta[/tex]), in degrees, are, respectively:

[tex]v_{A} = \sqrt{(-22.474)^{2}+376.822^{2}}[/tex]

[tex]v_{A} \approx 377.492\,\frac{mi}{h}[/tex]

[tex]\theta_{A} = \tan^{-1} \left(\frac{376.822}{-22.474} \right)[/tex]

[tex]\theta_{A} \approx 93.413^{\circ}[/tex]

The resulting speed and direction of the airplane are approximately 377.492 miles per hour and 93.413°, respectively. [tex]\blacksquare[/tex]

Answer:

127.3 feet.

Step-by-step explanation:

The line from first base to third base is the hypotenuse of a right triangle, with the right angle at home base.

Since this is a right triangle, we will use the Pythagorean Theorem to find the hypotenuse.

So, let a = one side and let b = the other side of the right triangle. And, let c = the hypotenuse.

The Pythagorean Theorem is:

c^2 = a^2 + b^2.

So, c= sqrt(a^2 + b^2)

And we have: c= sqrt(90^2 + 90^2)

= sqrt(8100 + 8100) = sqrt(16,200)

= 127.3 ft.

Conclusion: The distance from first base to third base is 127.3 ft, (approximately).

Answer:

1/4

unsimplified = 2/8

Step-by-step explanation:

2/8 is your answer because

you can see here that there are 8 bars that are being covered by his total sales. That means that 8 is the denominator, then, the money is going 2 more bars than 225 dollars. So if we see, then we can find out that the sales are going up till 275, and the difference of 275 and 225 is 50. And each bar over here represents a difference of 25. That means that 2/8 (1/4) of the sales are more than $225.

So hence, your answer is 1/4

Answer:

1/4

Step-by-step explanation:

From inspection of the box plot:

The left whisker (min value) to Q1 represents the bottom 25% of the data

Q1 to Q2 represents the second 25% of the data

Q2 to Q3 represents the third 25% of the data

Q3 to the right whisker (max value) represents the top 25%

Therefore, the sales of over $225 represent the top 25% of the data.  

25% represented as a fraction is 25/100 = 1/4
