Step-by-step explanation:
2 (x-3)-4 (x+3)
(-7) × (-5) = 35
2 × (-8) = -16
(-11) × 4= (-44)
-8× 8 = (-64)
(-9) × (-9)= 81
(-17) × (-2) =34
(-10) ÷ -2 = 5
44 ÷ (-11)= (-4)
Answer:
y = 100°
Step-by-step explanation:
x = 40° (vertical angles are congruent)
y is an exterior angel of a triangle that has two opposite internal angles, x (40°) and 60°.
According to the exterior angle of a triangle, thus:
y = 40 + 60
y = 100°

-2x-y=3 ...(1)
x+2y=4 ...(2)
multiply (2) by 2 and add to (1)
-2x-y+2x+4y=3+8
3y=11
y=11/3
from (2)
x=4-2y=4-2(11/3)
or x=4-(22/3)
=(12-22)/3=-10/3
