3×3 + 3×3/8=x
9+9/8=x
9+1+1/8=x
10 1/8=x
Answer:
x=9
Step-by-step explanation:
50 degrees and (10x-40) degrees are alternate interior angles and are, as such, equal. Thus, 50=10x-40, or 90 = 10x, or x = 9.
Answer:
129.3 in²
Step-by-step explanation:
The shaded segment is calculated as
area of sector ABC - area of triangle ABC
area of sector = area of circle × fraction of circle
A = πr² × 
= π × 18² × 
= 324π ×
= 54π in²
area of Δ ABC =
× 18 × 18 × sin60° ≈ 40.30 in²
Then
shaded area = 54π - 40.30 ≈ 129.3 in² ( to the nearest tenth )
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
x = 5 x = 4
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 4
