Answer:
n = 6
Step-by-step explanation:
n - 10= 5/6n - 7 - 1/3n
n - 10 = 15/18n - 7 - 6/18n
n - 10 = 9/18n - 7
18/18n - 10 = 9/18n - 7
9/18n = 3
1/2n = 3
n = 6
Answer:
y= 35/2 when x=5
x=6 when y =21
Proportinal relatiionships: y=−x
, y=15x
Step-by-step explanation:
The formula for direct variation is
y= kx
If y=7 and x=2, we can solve for k
7 =k*2
Divide by 2
7/2 =k
y =7/2 x
Now if x=5
y =7/2 * 5
y =35/2
Now if y=21
21 =7/2 * x
Multiply by 2/7
21 * 2/7 = 7/2 * 2/7 x
6 =x
Which equation represents a proportional relationship?
y=−x
YES k = -1 Some people debate about having a negative constant, but everything I have read and taught says you can have a negative constant.
y=−5(x+1)
This does not go through the origin so no
if x=0 y = -5
y = 5x + 1
if x = 0 y =1 so no
y=15x
YES k = 15
Answer:
The constant of proportionality is 2.
Step-by-step explanation:
z^2 = kW where k is a constant.
When z = 4 , W = 8 so
4^2 = 8k
k = 4^2/8
= 16/8
= 2.
Well I am going to guess and i don't know if it right but 156.25ml
