Answer:
A.
Step-by-step explanation:
38% = 38/100 = 0.38
A percentage is anything over 100
The 2 small black lines through the sides of the triangle indicate that the 2 sides are the same length.
Because the 2 sides are the same the 2 bottom angles are also the same.
This means that 9x +3 = 84
Now we can solve for x:
9x +3 = 84
Subtract 3 from each side:
9x = 91
Divide both sides by 9:
x = 81 / 9
x = 9

Answer:
4.5 pounds
Step-by-step explanation:
Convert them both to improper equations.
2 3/4 = 11/4
1 3/4 = 7/4
Then add.
11/4 + 7/4 = 18/4
Then simplify.
18/4 = 4 2/4 = 4.5
