What kind of triangle is this?

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

Have a terrificly amazing day!

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

Answer:

x = 8.5

Step-by-step explanation:

You have all three angles already, so it's easy: 90°, (4x - 8)°, (6x + 13)°

The sum of all angles is 180°

90 + (4x - 8) + (6x + 13) = 180

10x + 95 = 180

      - 95     -95

10x = 85

x = 8.5

Answer:

n + n+2 + m+4 = 87

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.

Answer:

$1.33 per student

Step-by-step explanation:

Mr. Luu spent 15.99 on new flashlights.

Total number of students = 12

We need to find the unit cost per student. It can be calculated by dividing the total cost and the total number of students.

[tex]C=\dfrac{15.99}{12}\\\\C=1.33[/tex]

So, the required cost per student is 1.33.

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

Answer:

The answer is 5

Step-by-step explanation:

-10 + 5 equals -5.

Think of 5 positive things and 10 negative things.

O O O O O

P  P  P  P  P  P  P  P  P  P

5 of the positive things will cancel out 5 of the negative things, leaving behind 5 negative things.

Answer:

12 ft

Step-by-step explanation:

First you do 16 x 2 +1 and you get 133, second you do 18 x 8 +1 = 145 third you need to subtract  145 - 133, and you get 12 feet.

Answer:

[tex]D = 63.717[/tex]

Step-by-step explanation:

The details that complete the question are:

[tex](x_1,y_1) = (0,42.78)[/tex]

and

[tex](x_2,y_1)=(90,42.78)[/tex]

Required

Determine how far the ball travelled

Distance is calculated using:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute values for x's and y's

[tex]D = \sqrt{(42.78 - 0)^2+(42.78-90)^2}[/tex]

[tex]D = \sqrt{42.78^2+(-47.22)^2[/tex]

[tex]D = \sqrt{1830.1284+2229.7284[/tex]

[tex]D = \sqrt{4059.8568[/tex]

[tex]D = 63.717[/tex]

Hence, the ball travelled a distance of 63.717 units

Answer:

x=106

Step-by-step explanation:

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
