Answer:
Hey there!
y=3/4x shows that the y-value is always 3/4 of the x-value.
Thus, if x is 4, y is 3. It always fits the 4:3 ratio.
The ordered pairs that satisfy this equation are: 28:21 and 16:12
Let me know if this helps :)
Answer:
v=3w
Step-by-step explanation:
v∝w
v=kw
24=8k
k=24/8 = 3
equation connecting v and w is
v=3w
Alright.
So let's say the number of adults is x.
Therefore, the number of boys is 7x + 1.
And then the total amount of girls is 3.5x + 0.5
So then:
x + 7x + 1 + 3.5x + 0.5 = 82
11.5x + 1.5 = 82
11.5x = 80.5
x = 7
So now we can figure out the number of male and female students.
Male students = 7x + 1
7*7 + 1
49 + 1
50
Male Students = 50
Female students = half of 50
50/2 = 25
Female Students = 25
Answer = 9m + 4
just do 15m subtracted from 6m to get 9m and let the 4 be
[-½, ¾]; use either "Substitution" or "Elimination" to do this, and you'll see that this answer is correct.
