The slope is the rate
words per minute
we can do
540 words in 3 minutes
divide by 3
180 words in 1 minute
thea=180wpm
elanor=225wpm
elanor>thea
and 225*2=450
answers are
Thea reads 180 words per minute.
Eleanor reads 450 words every 2 minutes.
After 1 hour of reading, Eleanor reads more words than Thea.
It can sometimes be rational
If we multiply the top equation by -4 we can get rid of the x so:
-4x+20y=-12
4x-4y=12
Add these up
16y=0
Y=0
X=3
Answer:
1;no
2; i don^t know
3;c
4;12
5:20
Step-by-step explanation:
reasons
1:sum of all side of triangle is 180 degree(here is 220)
3: try in copy and u will able to solve
4:first of all make 9 cm as shown in figure and draw 15 . finally measure the remaining side.
5: 3y+5y+y=180
9y=180
hence,y=20
