The answer would be 73 degrees because 62 +12 = 73
82 tens in the same thing as 820 because if you multiply 82 by 10 you get 820
<span>To determine the number of lawns he needs to mow to earn the desired money, Eli could perform a simple addition problem, adding $21 per lawn until he reached his goal number. This equation would be: 21 + 21 = 42 + 21 = 63 + 21 = 84 + 21 = 105 + 21 = 126 + 21 = 147 + 21 = 168 + 21 = 189 + 21 = 210 + 21 = 231 + 21 = 252. However, a better way would be to divide the desired amount by the cost per lawn and round to the nearest whole number. That equation is 235 / 21 = 12 lawns.</span>
Answer:
Step-by-step explanation:
We have two points
(
6
,
8
)
and
(
−
2
,
0
)
Explanation:
To find number of points of intersection, we should solve these pair of equations.
As
y
=
x
+
2
, we have

−
(
x
+

)
2
=

or
2
x

x

x

or
x

x

or

x

=

or
x
(
x

)
−
6
(
x
+
2
)
=
0
or
(
x
−
6
)
(
x
+
2
)
=
0
and hence
x
=
6
or
−
2
putting these values in
y
=
x
+
2
, we get
y
=
8
or
0
Hence, we have two points
(
6
,
8
)
and
(
−
2
,
0
)
