What is the value of x? round to the nearest hundredths place:

0.45 (x + 1.6) + 5x = 18

3.600

Step-by-step explanation:

0.25 (x+1.6) + 5x=18

Open the bracket first

0.25x+0.72+5x=18

Collect like terms

0.25x+5x=18-0.72

5.25x=18.72

Divide both sides by 5.25

x=3.566~3.600 (nearest hundredth)

x ≈ 3.2

Step-by-step explanation:

0.45 (x + 1.6) + 5x = 18

45/100 (x + 16/10) + 5x = 18

¹⁰⁾45x/100 + 720/1000 + ¹⁰⁰⁰⁾5x = ¹⁰⁰⁰⁾18

450x + 720 + 5000x = 18000

5450x = 18000 - 720

5450x = 17280

x = 17280/5450

x = 3.17

x ≈ 3.2
