You can find the unit rate when given a rate by setting up a proportion of the rate equal to how many per one.
40 miles per 2 hours = 20 miles per one hour.
20 miles/hour is a unit rate. (How many per one?)
Answer:
Answer: 3.75 g
Step-by-step explanation:
Assume the weight of the square is x.
The hanger is in balance so the left side is equal to the right side.
Equation therefore is:
Triangle + Square + 3 * circle = 5* square + circle
3 + x + (3 * 6) = 5x + 6
3 + x + 18 = 5x + 6
5x - x = 3 + 18 - 6
4x = 15
x = 15/4
x = 3.75 g

Find Radius
------------------------------
Radius = Diameter ÷ 2
Radius = 32 ÷ 2
Radius = 16

Find Area
------------------------------
Area = πr²
Area = π x 16²
Area = 256π mm²
------------------------------
Answer: 256π mm²

Answer: 3x > -28
Step-by-step explanation: We wrote an inequality to represent this situation.
Additionally, to solve this inequality divide both sides of the inequality by 3.
3x/3 > -28/3
x > -9 1/3
