Answer:
m=22.5
Step-by-step explanation:
m is proportional to n means there is some constant k such that:
m=kn
If m=5 when n=4 then we have the following equation to solve for our constant k:
5=k(4)
5=4k
Divide both sides by 4:
5/4 =k
So k=5/4 no matter what (m,n) pair they give you where the equation is m=kn.
m=(5/4)n
What is m when n=18?
m=(5/4)(18)
m=(5/2)(9)
m=45/2
m=22.5
Answer:
y=1/5x
Step-by-step explanation:
Slope is 1/5. The y-intercept is 0.
Answer:
n = -4/5
Step-by-step explanation:
-3/4 n + 1/8 n= 1/2
use the rules of signs for multiplication
-3/4 n + 1/8 n= 1/2
multiply both sides 8
-6n + n = 4
collect like terms
-5n = 4
divide both sides by -5
n=-4/5
or alternative form
n=-0.8
Points W, Y and Z form a right triangle, so we can find the length of c by using the Pythagorean theorem.
Using YZ as the base and YW as the side we get:
C = √(3^2 + 4^2)
C = √(9+16)
C = √25
C = 5 units
