Answer:
Step-by-step explanation: d I think
Let r be a radius of a given circle and α be an angle, that corresponds to a sector.
The circle area is
and denote the sector area as
.
Then
(the ratio between area is the same as the ratio between coresponding angles).
.
I got X=11
Minus 7x on both sides
The equation the becomes :
-2x +179=157
Subtract 179 from both sides
Equation now is:
-2x= -22
Divide -2 on both sides
X= 11
Answer:
One order pair is
(
2,0)
Step-by-step explanation:
What ordered pairs are the options?
Pick a value for
x
and solve for
y
. Or find the intercepts.
If
x
=
2
, then:
y
=
2
−
2
⇒
y
=
0
So we have
(
2
,
0
)
If
x
=
0
, then:
y
=
0
−
2
⇒
y
=
−
2
Here we have
(
0
,
−
2
)
You can simply use
0
for both
x
and
y
(intercept) to get the same answer.
Answer:
73 y/o
Step-by-step explanation:
Multiples of 9 between 50 and 80:
54 63 72 now add 1
55 64 73 now divide by 4 to find which has remainder of 1
73 y/o
