Answer:
y is 8
Step-by-step explanation:
First u do 13y-9y=4y
so you then have 4y-5=27
then you plus 5 to 27
u then have 4y=32
then divide 32 by 4
so you will get y=8
Answer:
1/8
Step-by-step explanation:
we know that
1 gal.= 3.8L
we can also write as
3.8L=1 gal
Firstly, we will find for 1L
so, we can divide both sides by 3.8


now, we will multiply both sides by 22



so, option-b.............Answer
P=2(L+W)
A=LW
given
P=62
62=2(L+W)
divide 2
31=L+W
minus W
L=31-W
sub into other one
A=LW
A=(31-W)(W)
228=31W-W^2
times -1
W^2-31W=-228
add 228 both sides
W^2-31W+228=0
factor
what 2 numbers multiply to get 228 and add to get -31
-19 and -12
(W-19)(W-12)=0
set to zero
W-19=0
W=19
W-12=0
W=12
sub back
L=31-W
L=31-12
L=19
or
L=31-19
L=12
the doorway is 12in by 19in
We can use the coordinates (-4, 5) and (0, 6) to find the slope.
Slope Formula: 
Solve: 
The slope of the line is \Large\boxed{\mathsf{1/4}}
Written in slope-intercept form: y = 1/4x + 6
Hope This Helped! Good Luck!
