That means it could be + - 3 degrees.
52 + 3 = 55
52 - 3 = 49
The temperature range is 49 to 55
Two corresponding sides and two corresponding angles are congruent.
<span>4x − 2y = 6 . . . . . (1)
2x + y = 5 . . . . . (2)
(2) x 2 => 4x + 2y = 10 . . . . . (3)
(1) - (3) gives: -4y = -4
y = -4/-4 = 1
From (2), 2x + 1 = 5 => 2x = 5 -1 = 4
x = 4/2 = 2
Solution is (2, 1)
Substituting the solution into the options gives that
</span><span>−4x − 2y = 10
−4y = 4 −4x
has the same solution.

So there's 20, 21, 22, 23, 24, 25, 26, 27 7 numbers total
so there are 3 numbers greater then 24 which would be 3/7= 0.42857....
There is only 1 number less then 21 which would be 1/7= 0.14285....
