Answer:
x=35/4
Step-by-step explanation:
S1- Divide both sides of the equation by the same term
-2100=-240x
-2100/-240=-240x/-240
S2- Simplify

Move the variable to the left
x=35/4
x = 109
this is pentagon
the sum of the interior angles of a polygon is
sum = 180°( n - 2) where n is the number of sides.
sum = 180° × 3 = 540° thus
x + 121+ 108 + 102 + 100 = 540
x + 431 = 540
subtract 431 from both sides
x = 540 - 431 = 109
Notice that the line with negative slope has a y-intercept of 5 and the line with positive slope has a y-intercept of 2.
On the other hand, the slope of the line with negative slope is -2, while the slope of the line with positive slope is 3 (This can be identified since in one case, the value of y decreases by 2 for each increase of 1 unit in x, and in the other, the value of y increases by 3 for each increase of 1 unit in x).
Using the y-intercept form to represent each line, the system of equations represented by the graph must be equivalent to:

From the given options, the one that displays the correct system of equations is option A.
Therefore, the answer is:
B is as it is a logical form of reasoning. if a=50, b=30, c=20
if a > b and b > c then a > c
Answer:
Combine like terms for the than you do to other side the multiply last for least you divide both sides
