Step-by-step explanation:
4x + 0.2=0.9
transposing 0.2 to RHS
=> 4x =0.9-0.2 => 4x=0.7
transposing 4 to RHS
=> x=0.7÷4
=> x=0.175

Answer:
Subtract 0.2 from both sides of the equation.
Step-by-step explanation:
4x + 0.2 = 1.9
The first step would be to subtract 0.2 on both sides.
4x +0.2 - 0.2 = 1.9 - 0.2

Answer:
y = -3x + 18
Step-by-step explanation:
y = mx + b
m = -3
6 = (-3) * 4 +b
b = 6 - (-3) * 4
b = 6 +12
b = 18
y = -3x + 18
Answer:
48
Step-by-step explanation:
65 + 70 + 73 + 49 +61 + 38 + 41 + 16 + 19 = 432
432 ÷ 9 = 48
25% = 25/100 = 0.25
9*0.25 = 2.25.
