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
The answer to the question is 10
Infinitely many, because if you simplified the right side, it would equal the left side.
Answer:
It takes 40 cartridges per book (B) and 30 cartridges per magazine (M) and Sarah wants to use at most 300 cartridges.
.. 40B +30M ≤ 300
It takes 200 pages to print a book and 80 pages to print a magazine and Sarah wants to use at most 1200 pages.
.. 200B +80M ≤ 1200
Hope this helped!
Answer:
(x+20) explains the elena walked 20 minutes more than Lin
Step-by-step explanation:
(x+20) explains the elena walked 20 minutes more than Lin
As given in the question that elena walked 20minutes more than lin means if elena walked x then lin walked (x+20) and also jada walked twice as long as elena means 2(x+20) and according to question jada walked 90 minutes means 2(x +20) = 90
