Yes because
Kate: 3X2 = 6
Jake: 3X2 = 6
Emily: 3X2 = 6
add all of those together and you get 18
Answer:

Step-by-step explanation:
Given
When mass = 4kg; Acceleration = 15m/s²
Required
Determine the acceleration when mass = 10kg, provided force is constant;
Represent mass with m and acceleration with a
The question says there's an inverse variation between acceleration and mass; This is represented as thus;

Convert variation to equality
; Where F is the constant of variation (Force)
Make F the subject of formula;

When mass = 4kg; Acceleration = 15m/s²


When mass = 10kg; Substitute 60 for Force



Divide both sides by 10


<em>Hence, the acceleration is </em>

1a. The equation is x-35+x+5+x
There it is i found it :)
It would be the letter A.
I hope this helps! <3
