Answer:70 degrees and 150 degrees
Step-by-step explanation: The angles of a quadrilateral add up to 360. So the sum of the two angles is 360 - (55+ 85) = 220.
After that you can model the sum of the angles with an equation:
7x + 15x = 220
22x = 220
x = 10
then you plug in x for each angle 7(10) = 70 and 15(10) = 150
Number = -14
(-14)+(-6)=-8
(-8)*(-3)=24
Answer:
The solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .
Option (D) is correct .
Step-by-step explanation:
As given the equations are .
4x+y=5
3x+y=3
Subtracted 3x+y=3 from 4x+y=5 .
Thus
4x - 3x + y - y = 5 - 3
x = 2
Put in the equation 4x+y=5 .
4 × 2 + y = 5
8 + y = 5
y = -8 + 5
y = -3
Therefore the solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .
Option (D) is correct .
