Answers

Answer:

x = [tex]-\frac{4}{3}[/tex]

Step-by-step explanation:

Distributive Property:

3 (x - 4) = 12x

3x - 12 = 12x

Combine like terms and isolate the variable:

3x - 12 = 12x

-12 = 9x

[tex]-\frac{4}{3}[/tex] = x

x = [tex]-\frac{4}{3}[/tex]

Answer:

x = [tex]\frac{-4}{3}[/tex]

Step-by-step explanation:

3(x - 4) = 12x

3x - 12 = 12x --->by the distributive property of equality

-9x = 12 ---> subtraction property of equality

x = -9/12 ---> division property of equality

x = -4/3 as simplified

What is the surface area? how did you find it(filled-in formula)?​

Answers

Answer: 1719.22 mi squared

Step-by-step explanation:

you have to find the height first.

you only have r and hypotenuse

so

a^2 + b^2 = c^2

13^2 + b^2 = 29.1^2

169 + b^2 = 846.81

b^2 = 846.81 - 169

b^2 = 677.81

b = 26.03

height = 26.03

surface area formula :

          _______

πr(r+_/h^2+r^2)

                   ___________

π(13) [13 + _/26.03^2 + 13^2]

= 1719.22

£110 is divided between Sara, Gordon & Malachy so that Sara gets twice as much as Gordon, and Gordon gets three times as much as Malachy. How much does Sara get?

Answers

Answer:

£66

Step-by-step explanation:

Find out the total units they 3 have altogether.

Sara = 6 units as it's 2 x 3 = 6 units and they mentioned that she got twice as much as Gordon

Gordon = 3 units as it mentioned got 3 times as much as Malachy

Malachy = 1 unit as they didn't mention one, two or three or more times as much as anyone else in the question.

6 + 3 + 1 = 10 units.

Find out how much is 1 unit, then find out how much Sara have with the units she have.

10 units = £110

1 unit = £110 ÷ 10 = £11

Sara has 6 units, so...

6 units = £11 x 6 = £66

6a-1÷7=4. . . . . . . . . . .. . . ​

Answers

Answer:

a=29/42

Step-by-step explanation:

6a-1÷7=4

first write the division as a fraction

6a-1/7=4

add 1/7 to each side

6a=4+1/7

which is equal to

6a=29/7

divide both sides by 6

a=29/42

PLEASE HELP if 5 more than 3 times a number is -4, what is the number?

Answers

Answer:

x = -3

hope it's helpful ❤❤❤

THANK YOU.

Hey there!

The answer to your question is "n = -3"

First, we can start by writing the equation as it says. "3 times a number" represents a number times 3, or "3n"

3n

Next, "5 more" represents addition, so "+ 5"

3n + 5

Finally, "is -4" means it is equal to -4, so "= -4"

3n + 5 = -4

Now that we have our equation, we can solve:

3n + 5 = -4

First, we subtract "5" from both sides of the equal sign:

3n = -9

Lastly, we divide both sides by "3".

n = -3

132 degrees

Step-by-step explanation:

Find the figure attached

Note that the sum of the interior angle of an hexagon is 720 degrees. Hence;

75 + 160+x+108+113+132 = 720

x+588 = 720

Subtract 588 from both sides

x+588 - 588 = 720 - 588

x = 132

Hence the value of x is 132 degrees

A team can spend no more than $300 on shirts. The team has already spent $80. How many shirts for $15 each can they still buy? A. Write the inequality that represents the situation. B. Explain why you chose the inequality sign. C. Without solving, explain how you know that 20 is not a solution,​

Answers

Answer: 14 shirts

A .   s (stands for shirts) <( less then or equal to) 14

B. because it can be exactly 14 shirts or less than 14 shirts depending if oyu want to use all the money

C. 20 would be a solution if you wouldnt have already spent the 80 dollars on other things, since the team did it  would be too much money.

Step-by-step explanation:

300- 80 = 220

220/ 15 = 14.6  round 14.6 to 14 (because you cant buy half a shirt)

you can get 14 shirts

In a circle with radius 7.8, an angle intercepts an arc of length 44. Find the angle in radians to the nearest 10th.

Answers

Given:

Radius of a circle = 7.8

Intercepted arc length = 44.

To find:

The angle in radians to the nearest 10th.

Solution:

We know that,

[tex]\text{Arc length}=r\theta[/tex]

Where, r is the radius of the circle and θ is the central angle in radians.

Substituting the values, we get

[tex]44=(7.8)\theta[/tex]

[tex]\dfrac{44}{7.8}=\theta[/tex]

[tex]5.641=\theta[/tex]

[tex]\theta\approx 5.6[/tex]

Therefore, the angle in radians to the nearest 10th is 5.6.
