48 because that's what you get following your equation in PEMDAS order :)
I think it should be D because if you look it is kind of common sense on how a triangle should look you should draw it out
Answer:
Here's what i know:
x + y = 23
3y / 20 =x
Here we can use substitution to help find our answer:
y + 3y/20 = 23
20y/20 + 3y/20 = 23
23y/20 = 23
23y = 23 * 20
y = 23 * 20 / 23
y = 20
x + 20 = 23
x = 3
8 - 6 = 2
You have 2 pieces left.
So 2/8 of the cake is left. If you simplify it is 1/4.
Hope this Helps!!
<span>perpendicular slope :
m1 * m2 = -1
1/2 * m2 = -1
m2 = -2
y = -2x + b
2 = -4 +b
b = 6
y = -2x + 6
