Answer:

6 x (3+9) add 3 and 9 = 12

6×12 = 72

Answer:

72

Step-by-step explanation:

3+9=12

12*6= 72

do everything in parenthesis first so to solve this you would do 3+9 which equals 12 then multiply 12 with 6 which gives you the answer 72 hope this helps have a good rest of your night :) ❤

Answer:

the answer is five because 3 times 5 is 15

Step-by-step explanation:

Answer:

Equation : - three times a number is equal to 15

3x = 15

x = 15 ÷ 3

x = 5

Answer:

Step-by-step explanation:

5h + c = 8.50

2h + 3c = 6

Multiply first equation by -3, then add it to second equation.

-15h - 3c = -25.50

 2h + 3c = 6

------------------------

-13h = -19.50

h = -19.50/(-13)  = 1.5

c = 8.50-5h = 1'

Given:

The equation is

[tex]\dfrac{3x}{7}+\dfrac{2}{7}=2[/tex]

To find:

The simpler equivalent form and solve the given equation.

Solution:

We have,

[tex]\dfrac{3x}{7}+\dfrac{2}{7}=2[/tex]

It can be written as

[tex]\dfrac{3x+2}{7}=2[/tex]

Multiply both sides by 7.

[tex]3x+2=14[/tex]

[tex]3x=14-2[/tex]

[tex]3x=12[/tex]

Divide both sides by 3.

[tex]x=\dfrac{12}{3}[/tex]

[tex]x=4[/tex]

Therefore, the simpler equivalent form of the given equation is [tex]3x+2=14[/tex] and the solution is x=4.

Answer:

Fred = 31

Natalie = 15

Step-by-step explanation:

We have Natalie and Fred's whos age are unknown, we know that when added, their ages equal 46. While when multiplied with Natalie's age 4 times, their ages is 91.

Create two systems :

F = Fred

N = Natalie

F + N = 46

4N + F = 91

We can change the first equation to Natalie's age alone :

N = 46 - F

Now substitute this into the second equation :

4(46 - F) + F = 91

Distribute :

184 - 4F + F = 91

Subtract 184 from both sides :

-4F + F = -93

Add like terms :

-3F = -93

Divide -3 from both sides :

F = 31

Therefore, Fred is 31 years old. Now replace his age in the first equation :

31 + N = 46

46 - 31

15

Therefore, Natalie is 15 years old.

This question is dealing with classification of triangles based on angles or on number of equal sides.

the triangle is called an Obtuse Scalene Triangle

- Acute angle is when the angle measures between 0 and 90 degrees.

- Obtuse angle is when the angle is greater than 90 but less than 180 degrees.

- right angle is when the angle is exactly 90 degrees.

- Reflex angle is when the angle is greater than 180 but less than 360 degrees.

- Isosceles triangle is one that has  2 equal sides.

- Equilateral triangle is one that has 3 equal sides.

- Scalene triangle is one that has no equal sides.

The lengths of the three sides of the triangle given are;

5 cm, 9 cm, and 12.7 cm

The three sides are not equal and from definition above it is called scalene triangle.

The angle given is 128° and from definition earlier, it is an obtuse angle.

In conclusion, the triangle is called an Obtuse Scalene Triangle

Responder:

suma de ángulos interiores = 900 °

Suma de ángulos exteriores = 360 °

Explicación paso a paso:

Un heptágono es un polígono de 7 lados:

Para cualquier polígono con n lados:

El ángulo exterior del polígono suma 360 °

Por lo tanto, la medida de cada ángulo central de un heptágono es:

Suma de ángulos exteriores / número de lados

360 ° ÷ 7

= 51,43 °

El ángulo interior de un polígono se obtiene mediante la relación:

(n - 2) 180 °

Heptágono tiene 7 lados:

(7 - 2) 180 °

5 (180 °)

= 900 °

Por tanto, suma de ángulos interiores = 900 °

Suma de ángulos exteriores = 360 °

The sign would be negative because the pounds were lost not gained

Answer:

yes

Step-by-step explanation:

you can use the vertical line test- for every line going up and down there should only be one point. if there is one and only one, it's a function. if there are more than one per line, then it is not a function.

Answer:

£6.4

Step-by-step explanation:

£1 = $1.35

To find out the amount of £ , we would simply divide $8.70 by 1.35.

$8.70 / $1.35 = £6.4 rounded to 2 s.f.

Answer:

y=1.25x+3, $8.00

Step-by-step explanation:

3 is the variable. A cup of frozen yogurt will always be a set price of $3.00. The toppings are the variable, which will depend on how many the customer adds.

Therefore, the equation would be y=1.25x+3

x being the number of toppings added

If the customer orders one cup of ice cream with 4 toppings, the equation would look like:

y=(1.25*4)+3

y=(5)+3 = $8.00 for a four topping cup of frozen yogurt

Correct me if I'm wrong, thanks

Answer : y = 11x + 24

Ok!

Part A;   35 + 22 = 57   ---    22 ÷ 2 = 11      11 people every year

According to my calculations they got 11 more people every year because 22 is for 2 years so if you that by 2 you get 11.

Part B; 79 People :)

Answer:

m∠U = 75.7°

Step-by-step explanation:

use Law of Cosines:

9.6² = 3.8² + 9.8² - 2(3.8)(9.8)·cos U

92.16 = 14.44 + 96.04 - 74.48·cos U

92.16 = 110.48 - 74.48·cosU

-18.32 = -74.48·cosU

cos U = -18.32/-74.48

cos U = 0.24597

arccos U = 75.7

Answer:

m∠U = 75.7°

Step-by-step explanation:

its on delta and if you use a calculator then its m∠U = 75.7°

Answer:

3=x

Step-by-step explanation:

multiply 5 times 2x and 4 which is 10x-20

then you have -10=10x-20

then add 20 to both aides and you'll have

30=10x then divide by 10 to get x alone

and you have

3=x

Step-by-step explanation:

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator. To do this, you need to find the least common multiple (LCM) of the two denominators.

Answer:

A)  125.4 yards

Step-by-step explanation:

the diagonal would represent the hypotenuse of a right triangle with legs equal to 115 and 50

115² + 50² = c²

c² = [tex]\sqrt{15725}[/tex] which is approx 125.4
