3x + 6y = -2......multiply by -5
15x + 30y = -10
--------------------
-15x - 30y = 10 (result of multiplying by -5)
15x + 30y = -10
--------------------add
0 = 0
there are infinitely many solutions
<span>Angle T = Angle C, let them equal x
So x + x + 140 = 180
2x = 40
x = 20
So Angle T = 20 degrees </span>
Answer:
What do you mean?
Step-by-step explanation:
The conjecture or hypothesis given based on the attached graph is that there has been a general increase in the total loss of the Greenland Ice Sheet since 2007. However, since 2013, the rate at which the total loss increased began to decline.
<h3>What is a conjecture in math?</h3>
In mathematics, a hypothesis or a conjecture is a speculative conclusion or assertion that is stated without evidence.
<h3>How do you write a Conjecture ?</h3>
You must discover a trend or make some type of remark. For example, you may have observed that the list is increasing by twos.
You draw a conclusion based on the pattern you saw, just as you did when you determined that 18 would be the following number.

Answer:
(3x + 18) + 93 = 180
23 + X
Step-by-step explanation:
(3x + 18) + 93 = 180, its supplymentery
180 - 93 = 87
87 - 18 = 69
3x = 69
69/3 = 23
23 = X
