Answer:
-3
Step-by-step explanation:
divide 7 on both sides -21/7 = -3
w=-3
Answer:
59°
Step-by-step explanation:
From the diagram, shown in the attachment line x and y are parallel lines.
Angle 7 and angle 6 are angles on a straight line.
The two angles will add up to 180 degrees.

But angle 7 measures 121°.
This implies that:

Solve for angle 6 to get;
\

The correct answer is 1/3f +36 = 85. You can figure this out by reading this "The number of State Parks in California is 36 more than one third the number of State Parks in Florida" and writing it as an equation.
85 = 1/3f + 36
Answer:
The answer in the attached figure
Step-by-step explanation:
