30(x - 10) = 120
Use distributive property to remove the parenthesis
30x - 30(10) = 120
30x - 300 = 120
move the constant to the right side
30x - 300 = 120
30x = 120 + 300
30x = 420
solve for x by moving 30 to the right side, multiplication will be division after moved to the right side
30x = 420
x = 420/30
x = 14
The value of x is 14
Answer:multiply 470 by 3
Step-by-step explanation:
Since the rate has been solved and it is 470 you multiply 470 by 3 to find out how far it traveled in 3 hours.

Answer:
The coordinates of b are: (x, y) = (3, -4)
Step-by-step explanation:
Given
Given that the midpoint of the ab is:
The coordinates of a are:
To determine
The coordinates of b = ?
Let b (x, y) be the coordinates of b.
Given that the midpoint of the ab is m(-2, -1)
Thus,
(x - 7) / 2 = -2, (y + 2) /2 = -1
now solving
(x - 7) / 2 = -2
(x - 7) = -2 × 2
x - 7 = -4
adding 7 in both sides
x - 7 + 7 = -4 + 7
x = 3
and solving
(y + 2) /2 = -1
(y + 2) = -1 × 2
y + 2 = -2
subtracting 2 from both sides
y + 2 - 2 = -2 - 2
y = -4
Thus,
The coordinates of b are: (x, y) = (3, -4)
