Answer:
x = 3
y = 8
Step-by-step explanation:
ok we will substitute
y = x + 5
into the second equation
4x + y = 20
4x + (x + 5) = 20
5x + 5 = 20
5x = 15
x = 3
y = x + 5 = 3 + 5 = 8
Answer:
75.2 kg
Step-by-step explanation:
His mass now is 80 kg which is 100% of his mass since 100% is the entire amount. He wishes to reduce his mass by 6%.
100% - 6% = 94%
After reducing his mass by 6%, his mass will become 94% of his original mass, 80 kg.
We need to find 94% of 80 kg.
94% of 80 kg = 94% × 80 kg = 0.94 × 80 kg = 75.2 kg
