5x+2(x+9)=x+4x+43how do you solve this?

x = 25/2

this is your answer

Step 1. Simplify x + 4x + 43 to 5x + 43

5x + 2(x + 9) = 5x + 43

Step 2. Cancel 5x on both sides

2(x + 9) = 43

Step 3. Divide both side by 2

x + 9 = 43/2

Step 4. Subtract 9 from both sides

x = 43/2 - 9

Step 5. Simplify 43/2 - 9 to 25/2

x = 25/2

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
