Answer:
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)
Answer:
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
