0.3(x + 3 ) = 0.3x + 0.9 ;
We solve the equation 0.5 - 0.2x = 0.3x + 0.9   /  - 0.3x;
0.5 -0.2x = 0.9   / -0.5;
-0.2x = 0.4        / × 10 ;
-2x = 4             / ÷ ( - 2 );
x = -2 ;
The solution of the equation is -2 .

Answer:

B(m)=A(m)-D(m)

B(m)=176m

Step-by-step explanation:

we are given

Walking on his own, the distance, D, in feet, that Roberto can cover in M, minutes is given by the function

D(m)=264m

When he walks on the moving sidewalk at the airport, the distance, A, in feet, that he can cover in m m minutes is given by the function

A(m)=440m

B is the distance, in feet, that Roberto would travel on the moving sidewalk in  m minutes if he were standing still

moving sidewalk distance = standstill distance + walking distance

A(m)=D(m)+B(m)

so, we get

B(m)=A(m)-D(m)

now, we can plug values

B(m)=440m-264m

B(m)=176m
