Find the circumference of the circle

Step-by-step explanation:

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.

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

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

Answer:

4x² - 4x - 1

Step-by-step explanation:

Given

4(x² - 2x) + (x - 1)(x² + x + 1) - x(x² - 4) ← distribute all parenthesis

= 4x² - 8x +x ³ + x² + x - x² - x - 1 - x³ + 4x ← collect like terms

= 4x² - 4x - 1

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:

Straight lines and Curves with tangents

Step-by-step explanation:

Simultaneous equations system

Replace y = -4x into y = 3x + 28

-4x = 3x + 28

Minus both side by 3x

-7x = 28

x = -4

Recheck : - 4 x (-4) = 3 x (-4) + 28
16 = -12 +28 = 16 (t)

Answer:

(- 4, 16 )

Step-by-step explanation:

y = 3x + 28 → (1)

y = - 4x → (2)

substitute y = 3x + 28 into (2)

3x + 28 = - 4x ( add 4x to both sides )

7x + 28 = 0 ( subtract 28 from both sides )

7x = - 28 ( divide both sides by 7 )

x = - 4

substitute x = - 4 into (2)

y = - 4(- 4) = 16

solution is (- 4, 16 )

To maximize the length of the third side, which I'll call x, it needs to be one of the two shorter sides.

So by the triangle inequality theorem, 6+x>12 meaning the minimum whole number value of x is 7.

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).

(reciprocal is 4/3)

37.5 x 4 = 150

150 / 3 = 50

Answer:

50

Step-by-step explanation:

74/1 divided by 3/4 is

74/1 times 4/3

296/3 which equals 50

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
