Answer:

x = 5

Step-by-step explanation:

2x - 7 = -3x + 18

2x - 7 + 7 = -3x + 18 + 7

2x = -3x + 25

2x + 3x = -3x + 25 + 3x

5x = 25

x = 5

Answer:

x=5

Step-by-step explanation:

2x−7=−3x+18

Step 1: Add 3x to both sides.

2x−7+3x=−3x+18+3x

5x−7=18

Step 2: Add 7 to both sides.

5x−7+7=18+7

5x=25

Step 3: Divide both sides by 5.

x=5

How many times smaller is 2 × 10^-10 than 4 × 10^-5

natta225 [31]

Answer:

200,000

Step-by-step explanation:

To find how many times smaller is smaller number than greater number, divide greater number by smaller number.

Greater number $=4\times 10^{-5}$

Smaller number $=2\times 10^{-10}$

Then

$\dfrac{\text{Greater number}}{\text{Smaller number}}\\ \\=\dfrac{4\times 10^{-5}}{2\times 10^{-10}}\\ \\=\dfrac{4}{2}\times \dfrac{10^{-5}}{10^{-10}}\\ \\=2\times \dfrac{1}{10^{-5}}\\ \\=2\times 10^5\\ \\=2\times 100,000\\ \\=200,000$

Can you solve any of these geometry problem?

Fudgin [204]

Answer:

1. I don't know how to solve that sorry :(

2. B. It is a diameter

3. 30° = q

4. I don't know sorry :(

Step-by-step explanation:

1. I don't know how to solve that sorry :(

-----------------------------------------------------------

2. B. It is a diameter

------------------------------------

3. All triangles = 180°

180° = 60° + 90° + q

180° = 150° + q

180° - 150° = 150° - 150° + q

30° = q

180° = 60° + 90° + 30°

180° = 150° + 30°

180° = 180°

------------------------------------------

4. I don't know sorry :(
