Perimeter of rectangle=66
length of rectangle=L
width of rectangle=w
P of a rect.= 2(length)+ 2(width)
66= 2L+2w
if the length is 7in more than the width, then
L=7+w
Now we will substitute 7+w in for L. Here is our new equation:
66=2(7+w) + 2w
Solve for w
66=14+2w+2w
66=14+4w
52=4w
w=13
L=7+13, so L=20
I hooe this is explained well enough
Step-by-step explanation:
option no 2 is correct
36 I hope is helpful
11x° is interior angle of ladder to the ground
and 7X° is interior angle of ladder to the wall
exterior angle of a ladder to wall is 180-7x
and exterior angle of a ladder to ground is 180-11x
K = -18 to check, -4 + k/3 = -10 is the equation. -18/3 = -6, and -4 + -6 = -10. Mark as branliest if you can. :)
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.
