Remember
all angles add to 180
x+y+z=180
one is 2 times as another
x=2y
measure of 3rd angle (z) is 20 more than smalllest
since y has to be doubled to get x, y is smallest
z is 20 more than y
z=20+y
we have
x=2y
z=20+y
sub those
x+y+z=180
2y+y+20+y=180
4y+20=180
minus 20 both sides
4y=160
divide 4
y=40
sub back
x=2y
x=2(40)
x=80
z=20+y
z=20+40
z=60
the angles are
80 degrees, 40 degrees, 60 degrees
Answer:-23/5
Step-by-step explanation:
-3/5-8/2
-3/5-4
-3+20/5
-23/5
1200 milligrams because 400 times 3 would equal a full 24 hours
Answer:
6
Step-by-step explanation:
3(x+2) = 4x
3x + 6 = 4x <- you times the x and 2 that is inside of the parentheses by the 3 that is on the outside
3x - 3x + 6 = 4x - 3x <- you have to subtract the 3x from the left side and you have to do the same on the right so you can get the numbers alone.
6 = x
