solve the inequality of 2x + 5 _> 47

Answers

Answer 1
Answer.[tex]2x + 5 > 47 \\ 2x > 47 - 5 \\ 2x > 42 \\ x > \frac{42}{2} \\ x > 21[/tex]Domain . ( 21 , ∞ )
Answer 2
2x + 5 _> 47

Subtract 5 on both sides

2x _> 42

Divide the whole equation by 2. And since 2 isn’t a negative, the sign will stay the same

x _> 21

Hope it helped!

Answer:

PQ=30

Step-by-step explanation:

Knowing that the segment has 3 parts that are 3:1:1 and sum up to 50, you could find how much 1 would equal by finding the total in relation to the ratio (doing 3+1+1) which gets you 5 parts. Then you can divide the total (50) by 5 to figure out how much one part would equal (10). Now, since you know that 1 part is equal to 10 and that PQ is 3 parts, you can find that PQ is equal to 3x10, or 30.

Answers

Answer: the variable is p=6 .

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable

Answer:

p = 6

Step-by-step explanation:

Step 1: Simplify both sides.

3 + 2p − 4 = 11

3 + 2p + −4 = 11

(2p) + (3+−4) = 11 (Combine Like Terms)

2p + −1 = 11

2p − 1 = 11

Step 2: Add 1 to both sides.

2p − 1 + 1 = 11 + 1

2p = 12

Step 3: Divide both sides by 2.

2p/2 = 12/2

p=6

Find the other endpoint of the line segment with the given endpoint and midpoint. Endpoint (-9.9) and Midpoint (10,0) A (0.5.5) B (0,5) C (29,-9) D (-9.5, 4.5)​

Answers

Answer: C (29,-9). Explanation: Two the endpoint of the line, find the difference between the midpoint’s x and y and the end point’s x and y, and you add that to the midpoint.

The other endpoint of the given line segment is (29, -9).

If O(x, y) is the midpoint between the line segment AB with end points A(x₁, y₁) and B(x₂, y₂). The coordinate of the midpoint is:

x = (x₁ + x₂)/2; y = (y₁ + y₂)/2

Let A(x, y) be the other end point. Since one end point is (-9, 9) and Midpoint (10,0), hence:

10 = (x + (-9))/2

20 = x - 9

x = 29

0 = (y + 9)/2

0 = y + 9

y = -9

Therefore the other endpoint of the given line segment is (29, -9).

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

5x - 2w + t = 0

Solve for x.

5x - 2w + t = 0

5x = 2w - t

x = (2w - t)/5

Solve for w.

5x - 2w + t = 0

5x + t = 2w

w = (5x + t)/2

Solve for t.

5x - 2w + t = 0

t = 2w - 5x

Thus,

The value of x, w, and t is given above.
