Answer:

m=7

Step-by-step explanation:

step 1: -3m+6m-12=9

step 2: 3m-12=9

step 3: 3m=21

step 4: m=7

Answer:

m=7

Step-by-step explanation:

1. Simpilfy both sides of the equation & combine like terms

2.  Add 12 to both sides

3. Divide 3 from both sides

Answer:

y = (6/5) - (7/5) x

Step-by-step explanation:

goal: to rearrange the equation such that it takes the form:

y = f(x) ; where f(x) is an expression in terms of x

Given:

7x+5y=6   subtract 7x from both sides

5y = 6 - 7x   (divide both sides by 5)

y = (6-7x) / 5

y = (6/5) - (7/5) x

Answer:

3160

Step-by-step explanation:

3.16 x 10^3

10^3 = 1000

so you move the decimal point three times to the right

I hope this helps

Answer:

3,160

Step-by-step explanation:

This is expressed in scientific notation. Since 3 is positive, that means the number is actually larger than 3.16, not smaller.

You would take

3.1600

and move the decimal point 3 spaces to the right

31.600

316.00

3160.0

3,160 is your answer

Hope this helps :-)

Answer: 1.5x

Step-by-step explanation:

Answer:

1.5x + 3 = y

Step-by-step explanation:

−6x = 12 − 4y

1.  Subtract 12 from both sides: −6x − 12 = −4y

2.  Divide −4 to both sides: -6x-12 over -4 = -4y over -4

A. 56 52 feet

Step-by-step explanation:

[tex]d = 18 \: ft \\ c = \pi \: d \\ c = 3.14 \times 18 \\ c = 56.52 \: ft[/tex]

The closest to the circumference is  56 52 feet.

It is required to find the circumference.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

Given:

Diameter of a circle is 18 feet.

Radius=18/2=9  feet.

We know that

circumference of the circle= 2πr

According to given question we have,

circumference of the circle= 2πr

circumference of the circle=2 π*9

circumference of the circle=56.54 feet.

Therefore, the closest to the circumference is  56 52 feet.

C. x = -7

2x + 23 = x + 16

x = -7

Mr. Gonzalez's monthly sales must be $87,500.

"It is a number or ratio that can be expressed as a fraction of 100"

For given example,

Let 's' represents the monthly sale.

So, the annual sales are 12 × s

He makes 4% commission on all of his sales.

So, the commission on (12 × s) sales would be,

= 12 × s × (4%)

= 12× s × 0.04

Mr. Gonzalez wants to earn $60,000 this year.

So, we get an equation,

⇒ 18000 + (12 × s × 0.04) = 60000

⇒ 12 × s × 0.04 = 60000 - 18000

⇒ 12 × s × 0.04 = 42000

⇒ s × 0.04 = 42000/12

⇒ s × 0.04 = 3500

⇒ s = 3500/0.04

⇒ s = 87500

Therefore, Mr. Gonzalez's monthly sales must be $87500.

Answer:

7°

Step-by-step explanation:

Since, Point D is in the interior of angle ABC.

Therefore,

[tex]m\angle ABC = m\angle ABD + m\angle DBC\\

20x - 15 = 6x - 5 + x + 16\\

20x - 15 = 7x + 11\\

20x - 7x = 11+15\\

13x = 26 \\ x = \frac{26}{13} \\ x = 2 \\ \\ m\angle ABD = (6x - 5) \degree \\ m\angle ABD = (6 \times 2 - 5) \degree\\ m\angle ABD = (12 - 5) \degree \\ \huge \red{ \boxed{ m\angle ABD = 7\degree}}[/tex]

RS = RT + TS = 24 cm

Let's plug our values into the equation above

24cm = 6x - 4 + 10cm

Combine like terms

24 cm = 6x + 6 cm

Subtract 6 cm from both sides

18 cm = 6x

Divide both sides by 6

3 = x

Plug 3 into the expression for RT

RT = 6(3) - 4 = 18 - 4 = 14 cm

Similarly, we know that TS = 10 cm and RS = 24 cm

24 cm - 10 cm = 14 cm

RT = 14 cm

14 cm = 6x - 4

Add 4 to both sides

18 cm = 6x

Divide both sides by 6

3 = x

Answer:

840

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 14 - 7 = 21 - 14 = 7

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 7 , thus

[tex]a_{120}[/tex] = 7 + (119 × 7 ) = 7 + 833 = 840
