Answer:
iv. The motion between A & B moves at a further distance than C & D's
v. The cyclist travels 800 meters
vi. It takes approx. 80 seconds
vii. The cyclist's speed is 10 meters per second (m/s)
viii. The cyclist's speed is also 10 meters per second (m/s)
vii. (2) The cyclist's average speed is 10 meters per second (m/s)
Explanation:
Speed is calculated using the formula distance divided by time (d/t)
vii (2) needs further explanation:
Though there is a moment of rest, the cyclist still travels the same speed throughout the entire trip. To check this answer however, you can total the distance and time the cyclist traveled and use speed formula to get 10 meters per second, again.
Calcium carbonate will be formed which is insoluble in water.

Answer:
x = 7
Explanation:
Simplifying
11x + 13 = 12x + 6
Reorder the terms:
13 + 11x = 12x + 6
Reorder the terms:
13 + 11x = 6 + 12x
Solving
13 + 11x = 6 + 12x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12x' to each side of the equation.
13 + 11x + -12x = 6 + 12x + -12x
Combine like terms: 11x + -12x = -1x
13 + -1x = 6 + 12x + -12x
Combine like terms: 12x + -12x = 0
13 + -1x = 6 + 0
13 + -1x = 6
Add '-13' to each side of the equation.
13 + -13 + -1x = 6 + -13
Combine like terms: 13 + -13 = 0
0 + -1x = 6 + -13
-1x = 6 + -13
Combine like terms: 6 + -13 = -7
-1x = -7
Divide each side by '-1'.
x = 7
Simplifying
x = 7
A suspension is the mixture with the largest particles.
