220 miles is how much Mrs. Johnson drove. because . . .
2x+x=330
2x is twice the amount of Mr. Johnson which equals Mrs. Johnson.
The plain "x" is how much Mr. Johnson drove.
2x+x= 3x
3x=330- x=110
If 'x' is how much Mr. Johnson drove then we multiply that by two to get 220.
If you calculate 20-3.58 the answer is $16.42
Answer:
since slope(m) = y2 -y1/x2- x1
-5 - 9/ -3 - (-3)= -14/0
m = -14/0 (undefined)
using the formula
y-y1 = m(x -x1)
y - 9 = -14/0(x - (-3)
y-9 = -14/0(x + 3)
0 = -14( x+3). (cross multiplication)
0 = -14x - 42
14x = -42
x = -3( equation of the line)
