Hello!
11 - (3x + 1) = 7(x - 6) + 2
Distribute the coefficients outside of the parenthesis:
11 - (3x) - (1) = 7(x) + 7(-6) + 2
Simplify:
11 - 3x - 1 = 7x - 42 + 2
Combine like terms:
10 - 3x = 7x - 40
Add 3x to both sides to isolate x:
10 = 10x - 40
Add 40 to both sides:
50 = 10x
Divide both sides by 10:
x = 5
Answer:
Since x and y are directly proportional , it means any increment in x leads to increment in y and vice versa, so if x is doubled y is also doubled

The answer to your question is: 1296
Step-by-step explanation:
Data
2000 --------- 900 students
2001 ---------- 180
2002 ---------- ?
900 students ---------------- 100%
180 students ---------------- x
x = (180 x 100) / 900
x = 20%
1080 students ------------- 100 %
x ------------- 20%
x = (20 x 1080) / 100
x = 216
Total number of students = 1080 + 216 = 1296

Answer:
67.17
Step-by-step explanation:
First, identify the hundreds digit (the 7)
Next, identify the next smallest place value (the 1)
Then, determine if 7 greater than or equal to 1. Yes, it is greater than 1, so round up. Increase the hundreds digit by one, so 7 becomes 8.
Finally, keep .17 and you get an answer of 67.17.
