Answer:
20:15
Step-by-step explanation:
baiscally add 4:3
4+3=7
then take the total of 35 and divide it by 7 you'd get 5.
4x+3x=35
7x=35
1x=5
4x=5×4=20
3x=5×3=15
4:3 therefore would be 20:15
Step-by-step explanation:
the numbers are all multiples of 7
the graph is upward
I am pretty sure it is 5/-2 (rise/run)

Step-by-step explanation:
Answer:
<em>r=6</em>
Step-by-step explanation:
<u>Proportions
</u>
We know M is directly proportional to 
This can be written as

Where k is the constant of proportionality which will be determined knowing that when r = 4, M= 160. Substituting in the equation above:


Solving for k:

The equation is:

Now find r when M=540:

Dividing by 2.5:

Taking cube roots:
![r=\sqrt[3]{216}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B216%7D)
r=6
