Answer:
-5y + 3x (or) 3x - 5y
Step-by-step explanation:
-8y-(x-4x)+3y
Solve the problem in the parentheses first. (x-4x)
-8y-(-3x)+3y
The problem within the parentheses is as simplified as we are going to get it. Now we can simplify the y values. (-8y + 3y)
-(-3x) -8y+3y
-(-3x) - 5y
Get our x value out of the parentheses now. -(-3x)
-(-3x) = +3x (two negatives makes a positive)
This leaves us with our simplified equation.
3x - 5y
or
-5y +3x
To find the area of a triangle, it it (width x height)/2 so plug in the numbers
(6x6)/2
36/2
18
then you multiply that by 4, because there are 4 triangles
18x4=72
then take the area of the square
6x6=36
then add them!
area=72+36
The area is 108!
Let's call their parts w,m and s
if will paid 1/3, then m+s=2w (they paid 2/3, which is twice as much as will did)
Now, we know that:
Micah and Sue paid in the ratio 2:3.
this means the 3m=2s
and m=2/3s
Again:
m+s=2w
and we substitute m:
2/3s+s=2w
5/3s=2w// multiply both sides by 3
5s=6w
we also know that s=w+6 (from the last sentence) so we substitute:
5(w+6)=6w
5w+30=6w
30=w
so, Will paid 30, Sue paid 36 (six more than him), Mike paid 24 (24:36 is the same ratio as 2:3, you can check this by dividing both 24 and 36 by 12: you have 2 and 3)
and the total was 30+36+24=90.
