Answer:
1. t = 48.654
2. 
3. 
4. 
Step-by-step explanation:
To solve equations using variables, perform inverse operations to undo each part and isolate the variable.
1. 
Multiply by 5.4 on both sides to undo division.
t = 9.01 * 5.4
t = 48.654
2. 
Multiply both sides by the reciprocal of 3/4 which is 4/3.

3. 
Convert 12 1/2 into an improper fraction.

Subtract 1/4 from both sides.

To subtract fractions without common denominators, convert 25/2 into a fraction with denominator of 4.

4. 
Subtract 2 2/3 from both sides.

Convert each fraction into improper fractions and then to common denominators.

Answer:
A
Step-by-step explanation:
∠ AOC = 90° and
∠ AOB + ∠ BOC = ∠ AOC , that is
x + 8 + 2x = 90
3x + 8 = 90 ( subtract 8 from both sides )
3x = 82 ( divide both sides by 3 )
x = 
Then
∠ BOC = 2x = 2 ×
=
≈ 54.67° ( to 2 dec. places )
