Answer:
a=-5
Step-by-step explanation:
subtract 3 from both sides
15=-3a
divide by -3
a=-5
24a-18a+12a is equal to 18a
hence, divide it by 6a
so you get 3a :)
I think that the basketball's volume would be greater than the softball because it has a radius of 5 and the softball has a radius of 2.
Answer:
The arrangement of the given equation in the slope - intercept form are

Step-by-step explanation:
Given:
x + y = 4 and
y - 2x = -5
Slope - intercept form :

Where,
m is the slope of the line.
c is the y-intercept.
When two points are given say ( x1 , y1 ) and ( x2 , y2) we can remove slope by
Slope,

Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.
So, the Slope -intercept form of
x + y = 4 is 
and
y - 2x = -5 is
3(x-2)=36
3x-6=36
3x=36+6
3x=42
x=42/3
x=14
Answer: 14
I hope this helped mate!
