Answer:
x = 7
Step-by-step explanation:
corresponding interior angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line
one is an obtuse and one is an acute angle in which sum up to 180°
(120°) + (7x + 11) = 180°
120° + 7x + 11 = 180°
131° + 7x = 180°
131° - 131° + 7x = 180° - 131°
7x = 49°
7x/7 = 49°/7
x = 7°
plug x in to check:
7(7) + 11 = 49 + 11 = 60

Answer:
x=−5/2 y+ 3/2
Step-by-step explanation:
Let's solve for x.
2x+5y=3
Step 1: Add -5y to both sides.
2x+5y+−5y=3+−5y
2x=−5y+3
Step 2: Divide both sides by 2.
2x/2
=
−5y+3
2x=
−5y+ 3/2
Answer:
x=−5/2 y+ 3/2
Answer:
{-2/7, 2/7}
Step-by-step explanation:
Here you're being asked to solve the given equation 49w^2-4=0 for w with the hint that the solutions are fractions.
49w^2-4=0 is the product of the sum and difference of two squares:
(7w - 2)(7w + 2) = 0
Setting each factor equal to zero and solving for w, we get:
{-2/7, 2/7} as the solutions.
