Answer:
x = 80 / 79 [improper fraction]
x = 1 ¹⁄₇₉ [mixed fraction]
x = 1 +
[decimal]
x ≈ 1.01 [decimal to nearest hundredth]
Step-by-step explanation:
10.3x + 4.5x = 15
(10.3 + 4.5)x = 16
(15.8)x = 16
(15.8)x / 15.8 = 16 / 15.8
x = 16 / 15.8
x = (16) / (15 + ⁸⁄₁₀)
x = (16) / (15 + ⅘)
x = (16) / (15 ⅘)
x = (16) / (79 / 5)
x = (16) × (5 / 79)
x = 80 / 79
x = 1 ¹⁄₇₉
x = 1 + ¹⁄₇₉
x = 1 +
x ≈ 1.01
