Answer:
The answer is x = 4
Step-by-step explanation:
1. First you need to distribute the 3/4 * (x + 8). This looks like (3/4) * (x) + (3/4) * (8) = 9
2. Next you simplify the distributed equation, 3/4x + 6 = 9
3. Now subtract 6 from both sides, 3/4x = 3
4. Multiply both sides by 4/3, 4/x * 3/4x = 3 * 4/3
5. Simplify, x = 4
The first fraction is saying that 12 cups over 3 dollars is equal to 9 dollars over however many cups. To make it correct it would be 12/3 = C/9.
Answer:
x = 2
Step-by-step explanation:
Since B is the midpoint, AB and BC are congruent in length.
5x-6 = 2x
5x = 2x + 6
5x - 2x = 6
3x = 6
x = 2
Answer:
Finding b:
57+b = 180 (linear pair)
b = 123
Finding c:
c = 123 (vertical angles are always congruent
