Answer:

x=5

Step-by-step explanation:

We kind of have to work backward.

First, we take 12+3 because when we move it over the equal sign, we make it the opposite.

12+3=15

Our new equation is now, 3x=15

We now take:

3x__=15

The blank represents x, which is 5.

Hope this helps!

3(x-1)=2x+9 help me :(

Flura [38]

3(x - 1) = 2x + 9
3x - 3 = 2x + 9
3x (-2x) -3 (+3) = 2x (-2x) + 9 (+9)
(3x -2x) = (9 + 9)
(x) = (18)
x = 18

x = 18 is your answer

hope this helps

Step-by-step explanation:

Rotation of 90°

(Clockwise)

(x, y) ---> (y, -x)

Rotation of 90°

(CounterClockwise)

(x, y) --> (-y, x)

Rotation of 180°

(Both Clockwise and Counterclockwise)

(x, y) ---> (-x, -y)

Rotation of 270°

(Clockwise)

(x, y) ---> (-y, x)

The ratio of violinists to cellists in the school orchestra must always be 7:3. If the school orchestra has 21 violinists, what

Papessa [141]

Given:

Violinists : Cellists = 7:3.

Number of violinists in the school orchestra = 21

To find:

The combined number of cellists and violinists.

Solution:

Let the number of violinists and cellists in the school orchestra are 7x and 3x respectively.

Then, combined number of cellists and violinists is

$\text{Combined number of cellists and violinists}=7x+3x$

$\text{Combined number of cellists and violinists}=10x$ ...(i)

Number of violinists in the school orchestra = 21

$7x=21$

Divide both sides by 7.

$x=3$

Now, the combined number of cellists and violinists is

$\text{Combined number of cellists and violinists}=10(3)$ [Using (i)]

$\text{Combined number of cellists and violinists}=30$

Therefore, the combined number of cellists and violinists is 30.

If x varies directly as y, and x = 200 when y = 11, find y when x = 500. Algebraic solution please.

zimovet [89]

Answer:

27.5

Step-by-step explanation:

x⠀⠀⠀⠀⠀|⠀⠀⠀⠀200⠀⠀⠀⠀|⠀⠀⠀⠀500

y⠀⠀⠀⠀⠀|⠀⠀ ⠀⠀ 11⠀⠀⠀⠀⠀|⠀⠀⠀⠀a

As x directly varies with y:

200 × a = 500 × 11

a = 5/2 × 11 = 27.5
