Answer:
answers are below
Step-by-step explanation:
<u>a. -6 ≤ 3x < 15</u>
steps in order to solve:
-6 ≤ 3x
= -6/3 ≤ 3x/3
= -2 ≤ x
3x < 15
= 3x/3 < 15/3
= x < 5
=> -2 ≤ x < 5
<u>b. -3 < 2x - 1 < 7 </u>
steps in order to solve:
-3 < 2x - 1
= 1 - 3 < 2x - 1 + 1
= -2 < 2x
= -2/2 < 2x / 2
= -1 < x
2x - 1 < 7
= 2x - 1 + 1 < 7 + 1
= 2x < 8
= 2x/2 < 8/2
= x < 4
=> -1 < x < 4
<u>c. 7 < -3n + 1 ≤ 13</u>
steps in order to solve:
7 < -3n + 1
= -1 +7 < -3n + 1 - 1
= 6 < -3n
= 6/-3 < -3n/-3
= -2 > n
-3n + 1 ≤ 13
= -3n + 1 - 1 ≤ 13 -1
= -3n <u><</u> 12
= -3n/-3 <u><</u> 12/-3
= n <u>></u> -4
=> -4 <u><</u> n < -2

Answer:
You have to simplify the fraction and turn it into a decimal.
Step-by-step explanation:
Meaning: Make the fraction smaller and turn it into the correct decimal.
EXAMPLE:
2/4 simplified is 1/2
1/2 is equal to 0.50
Convert to decimals.
5/7 = 0.71
4/6 = 0.67
So yes, 5/7 is greater than 4/6.
Or you can convert to denominators of 42:
5/7 = 30/42
4/6 = 28/42
Compare the the numerators.
30 > 28, so 5/7 > 4/6
