Answer:

x=12

Step by step explanation:

Step by step explanation:Add 9 to both sides :

15 = 2x - 9

15 + 9 = 2x - 9 + 9

Simplify:

24 = 2x

Divide both sides to get the result:

24 = 2x

24/2 = (2x)/2

Result:

x=12

Answer:

9

Step-by-step explanation:

I think I understand that question strange way to put it

A complementary angle is 90 degrees. The ratio is 2:3 so the equation would be:

2x+3x=90

5x=90

x=18

One of the angles would be 2(18) or 36 degrees and the other angle would be 3(18) or 54 degrees.

36+54 is equal to 90 degrees so it checks out.

14muffins are left. please give brainliest

Step-by-step explanation:

so first we need to figure out how many there are in total so if 4 muffins is 2/9 so every 2 muffins is 1/9 so we need 9x2 wich is 18 so there are 18 muffins in total but the stray dog ate 4 of them so 18-4 is 14 so the answer is 14muffins are left.

Step-by-step explanation:

3(6k+5)+ 3(6k+4)

open the bracket

18k+15+18k+12=0

collect like terms

18k+18k+15+12=0

36k + 27 =0

36k=-27

k=-27/-36

divide through by 3

k= -9/-12

still divide through by 3

k=-3/-4

minus cancel minus

k=3/4

Length :

12

feet

Width :

10

feet

Explanation:

Let the length of the garden be

x

feet.

Therefore, the breadth or width of the garden is

(

x

−

2

)

feet.

So, According to the problem,

x

(

x

−

2

)

=

120

⇒

x

2

−

2

x

=

120

⇒

x

−

x

−

120

[Transposing 120 to the L.H.S]

⇒

x

+

x

−

12

x

−

120

=

[Breaking

x

]

⇒

x

(

x

+

10

)

−

12

(

x

+

10

)

=

0

[Taking the like terms aside]

⇒

(

x

+

10

)

(

x

−

12

)

=

0

[Completing the factorisation]

We know, When two real quantities are multiplied and the product is zero, then one of them or both of them should be zero.

So, Either

x

+

10

=

0

or

x

−

12

=

0

So,

x

=

−

10

or

12

As

x

indicates length,

x

can't be negative.

So,

x

=

12

.

So, The length of the garden is

12

feet and the width of the garden is

(

12

−

2

)

feet =

10

feet.

Four possible numbers

-10

Four numbers that are not possible

100

120

20

10

Step-by-step explanation:

I choose the 4 possible numbers because if you add a negative to a negative, the answer will always be a negative. However if you added a positive like 100 to -3, the answer wouldn't be negative so that's why I chose those numbers.

Step-by-step explanation:

Tori + Brielle + Abby = 215

Give Tori spends x.

Brielle ; 2x and Abby ; 3x - 1

so

x + 2x + 3x - 1 = 215

6x - 1 = 215

6x = 216

x = 36

Tori spends $36 Brielle spends $72 and Abby spends $107.

The number 18 in the form of complex numbers will be written as 18 + 0i.

Every complex number may be represented in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element labeled I sometimes known as the imaginary unit, and satisfies the equation i² = 1.

The given number is 18. The number in the form of a complex number can be written as:-

Complex number =  a + bi

Complex number =  18 + 0i

Therefore, the number 18 in the form of complex numbers will be written as 18 + 0i.
