Answer: 
Step-by-step explanation:
For this exercise it is important to remember the following:
The constant of proportionality, which is represented as "k", describe the constant ratio of two quantities that are proportional (the independent and dependent variables).
In this case we know that the independent quantity represents the total members of the band and the dependent quantity represents the woodwind members of the band.
Since the band consists of 3 woodwinds for every 7 members of the band, we can conclude that the constant of proportionality for this relationship is:

Answer:
The answer would be 15.
Step-by-step explanation:
at the top you see that a 130° is shown. In a compass there is 180°. subtract 130 from 180 and you will get 50. subtract 5 from 50 and divide by 3 and you will get 15.
Answer:
x = 3.5
Step-by-step explanation:
(10x + 15) = 30
10x + 15 = 30 *
10x + 15 = 10 * 5
10x + 15 = 50 {Subtract 15 form both sides}
10x = 50 -15
10x = 35 {Divide both sides bt 10}
10x/10 = 35/10
x = 3.5
Answer:
4 2/3
Step-by-step explanation:
Any negatives in absolute value signs can be turned positive because it is the same distance from 0 in the number line. (right or left, but in this case, the distance is ALWAYS positive)
Answer:
x = (-7,7)
Step-by-step explanation:
1.add 5 on both side
2.divide each side of the equation by 2
3.take the square root of each side of the equation to solve for x
