Remember that you can convert percentages to decimals by dividing them by 100.
You can convert decimals to percentages by multiplying them by 100.
Here are my answers:
11.
(a) 55% < 0.75
(b) 0.23 < 28%
(c) 74% > 0.70
(d) 1/2 < 2/3
(e) 3/4 < 7/8
(f) 3/5 > 2/11
1. 1/4(x+3)=12=X+3-12*4/4=X-45/4. Then, x-45/4=0. So, 1. X=45. 2. x+4/3=12=3x-32/3*3=0*3. 3x-32=0. You add 32 to each sides. 3x=32. x=32/3. Therefore, 1. x=45 and 2. x=32/3
Y=8x because 42-26 is 16 and divide that by the difference between the hours to get how much you pay per hour

Answer:
C. 8
Explanation:
One way to solve this is to find 30% of each class, 28 and 24.
30% of 28:
28 • 0.30 = 8.4
30% of 24:
24 • 0.30 = 7.2
You can then find the average of these two numbers.
8.4 + 7.2 = 15.6
15.6 ➗ 2 = 7.8
7.8 rounds up to 8
Another way to solve is to first find the average number of people in each class.
28 + 24 = 52
52 ➗ 2 = 26
You can then find 30% of this number.
26 • 0.30 = 7.8
7.8 rounds up to 8
