2c – 4 = 3(4 – 2c)

please find c

Answers

Answer 1

Answer:

c = 2

Step-by-step explanation:

2c – 4 = 3(4 – 2c)

Expand brackets:

⇒ 2c – 4 = 12 - 6c

Add 6c to both sides:

⇒ 8c – 4 = 12

Add 4 to both sides:

⇒ 8c = 16

Divide both sides by 8:

⇒ c = 2

Answer 2

Answer:

c = 2

Step-by-step explanation:

First expand 3(4-2c):

3×4=12

3×-2c=-6c

Now our equation is :

2c-4 = 12-6c

Add 4 to both sides:

2c-4+4=12-6c+4

Simplify:

2c = -6c+16

Add 6c to both sides:

2c+6c = -6c+16+16

Simplify:

8c=16

Divide both sides by 8:

8c÷8 = 16÷8

c = 2

There are 22 male lambs and 28 female lambs in a yard.

Ten males and 14 females have been shorn.

One of the lambs escapes from the yard.

What is the probability that it is a shorn male?

Answers

Answer:

shorn male = 20%

Step-by-step explanation:

The probability that the escaped lamb is a shorn male is 1/5 or 0.2, which is 20%.

To find the probability that the escaped lamb is a shorn male, we need to calculate the ratio of shorn male lambs to the total number of lambs.

Number of shorn male lambs = 10

Total number of lambs = 22 (male) + 28 (female) = 50

Probability = (Number of shorn male lambs) / (Total number of lambs)

Probability = 10 / 50

Probability = 1 / 5

So, the probability that the escaped lamb is a shorn male is 1/5 or 0.2, which is 20%.

Find the value of xx, yy, and zz in the parallelogram below.

Answers

Answer: x = 36, y = 10, and z = -25

Step-by-step explanation:

99 and -3z +6 are same side interior angles, so they sum to 180 degrees.

99 -3z + 6 = 180

-3z = 75

z = -25

Opposite angles of a parallelogram are congruent

2x + 9 = -3x + 6

2x + 9 = 75 + 6

2x = 81 - 9

2x = 72

x = 36

9y + 9 = 99

9y = 90

y = 10

According to definition of parallelogram

opposite sides and angles are equal

Consecutive sides have sum 180°

[tex]\\ \rm\hookrightarrow 2x+9+99=180[/tex]

∠UTQ is an alternate interior angle of ∠URS

B. AABC is translated 2 units right, then rotated 90° clockwise about
the origin
C. AABC is translated 1 unit down, then rotated 90° clockwise about
the origin
D. AABC is translated 1 unit right, then rotated 90° clockwise about
the origin

Answers

Answer:

The answer is D) AABC is translated 1 unit right, then rotated 90° clockwise about the origin

Step-by-step explanation:

If you follow the steps translating triangle ABC to A"B"C" and rotating it. You will get that answer. I can envision it mentally simply by following one coordinate at a time which can help me during tests and is how the translations work.

For instance if you moved the A coordinate 2 units to the right it would sit on the y axis, and when rotated 90 degrees wouldn't 1 unit above the x axis but on it. You can simply use mental math for questions like this because they are simple enough to follow where you just pick a coordinate and do the translating and dilating based on what you are given.

Sorry if it's not a mathematical explanation but it's how I usually solve these questions! Hope I could help!!

The Sequence of Transformation that has been applied is; D. AABC is translated 1 unit right, then rotated 90° clockwise about the origin.

How to work with Translation Rotations?

From triangle translation of ABC to A"B"C" and rotation of it, we can see that;

If we moved the A coordinate 2 units to the right it would sit on the y axis, but when rotated 90°, it would be 1 unit on the x axis.

Thus, applying the principe of translation and rotation we can say that AABC is translated 1 unit right, then rotated 90° clockwise about

the origin.

PLEASE I NEED HELP QUICKLY!!! Find the solution for the given system of equations in the form (x,y). ​ -x+y=8 7x+3y=-6

Answers

Answer:

The answer D is correct.

Step-by-step explanation:

-x + y = 8 ⇒ ( 1 )

7x + 3y = - 16 ⇒ ( 2 )

y = 8 + x ⇒ ( 3 )

Let us take equation 2 and let us replace y with (8+x).

Let us solve and find the value of x.

7x + 3y = -16

7x + 3 ( 8 + x ) = - 16

7x + 24 + 3x = -16

10x + 24 = -16

10x = -16 - 24

10x = -40

x = (-4)

And now let us find the value of y.

For that, let us use equation (3)

Here, we have to replace x with -4 to find the value of y.

y = 8 + x

y = 8 - 4

y = 4

Now we have to the answers in the form ( x , y )

Let us write.

Answer: D. y= 15/x

Step-by-step explanation:

We have to test each explanation first, but I started with D because it is the most reasonable.

When you check the first column, you take 15 and divide it by 15. What do you get? 1.

1. X= 15 Y= 1 (15/15) = 1

When you check the second column, you take 15 and divide it by 5. What do you get? 3.

2. X= 5 Y= 3 (15/5) = 3

When you check the third column, you take 15 and divide it by 3. What do you get? 5.

3. X= 3 Y= 5 (15/3) = 5

When you use the fourth column, you take 15 and divide it by 1. What do you get? 15.

4. X= 1 Y= 15 (15/1) = 15

Since this all checks out, the answer is therefore correct.
