Sum of all the angles in Quadrilateral is equal to 360
so, 360 = 80+110+75+x
x = 360-265
x = 95
OPTION C IS YOUR ANSWER.
Hmmm..... let us try again...but this time with a different strategy,.... by the graph method.
The system is
3x + 4y =96
2x + 5y = 99.
We find solutions of each system and then plot them on a graph.
Solutions for equation 1 = (2, 22.5) and (30, 0)
Solutions for equation 2 = (49.5 , 0) and (1, 19.4)
Now, we plot both the equations on a graph paper and note its intersecting point.
Experimentally, we find the intersecting point is (12,15)
Thus, the solution for the system is x = 12 , y = 15.
Thus, we arrive at the conclusion 1 shirt costs 12$
1 cap costs 15$
Answer:
The answer is -22x² - 14x.
Step-by-step explanation:
You have to eliminate the brackets by multiplying :
Next you can simplify but there is no common terms in this expression so it remains the same.
3.00/12.50 = .24
This means the tip was 24% so it was more than 20%.
1.25/20=1x
1.25x=20
x=20/1.25=16
1 inch=16 feet
