If 5x+3=10x-17, what is the value of x

4 = x

Step-by-step explanation:

5x+3=10x-17

take away 5x from both sides

3 = 5x - 17

add 17 to both sides

20 = 5x

divide both sides by 5 to get x by itself

4 = x

x = 4

Step-by-step explanation:

Step 1: Write equation

5x + 3 = 10x - 17

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

5(4) + 3 = 10(4) - 17

20 + 3 = 40 - 17

23 = 23

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
