Answer:

x= - 35 over 89

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2

7

x−23+5x=18(x−1)

2

7

x+−23+5x=(18)(x)+(18)(−1)(Distribute)

7

x+−23+5x=18x+−18

7

x+5x)+(−23)=18x−18(Combine Like Terms)

7

x+−23=18x−1837

7

x−23=18x−18

Step 2: Subtract 18x from both sides.

7

x−23−18x=18x−18−18x

−89

7

x−23=−18

Step 3: Add 23 to both sides.

−89

7

x−23+23=−18+23

−89

7

x=5

Step 4: Multiply both sides by 7/(-89).

What is the length of s?​
Serggg [28]

Answer:

10

Step-by-step explanation:

We will use trigonometry to solve this problem.

We see that the side provided is the hypotenuse and the side we are looking for is opposite to the angle provided. Thus, we will use sin since sin uses opposite/hypotenuse.

Now we solve.

sin45 = x/14

sin45 * 14 = x

x = 9.899494936611665

Which expression is equivalent to one over five m − 20? (4 points)
exis [7]

Answer:

The equivalent to one over five m − 20 is one over five (m − 100) ⇒ B

Step-by-step explanation:

Let us solve the question

∵ One over five means \frac{1}{5}

∴ One over five m - 20 = \frac{1}{5} m - 20

→ By using the distributive property, take one over five as a common factor

  from both terms

∴ \frac{1}{5} m - 20 = \frac{1}{5} (\frac{\frac{1}{5}m}{\frac{1}{5}} - \frac{20}{\frac{1}{5}})

→ Simplify the bracket

∵  \frac{1}{5} m ÷ \frac{1}{5} = \frac{1}{5} m × 5 = m

∵ 20 ÷  \frac{1}{5}  = 20 × 5 = 100

∴  \frac{1}{5} (\frac{\frac{1}{5}m}{\frac{1}{5}} - \frac{20}{\frac{1}{5}}) = \frac{1}{5} (m - 100)

∴ \frac{1}{5} m - 20 = \frac{1}{5} (m - 100)

The equivalent to one over five m − 20 is one over five (m − 100)
