Question

1. Solve the compound inequality 30 < 10u < 120. (1 point)
3 < u < 4
3 > u > 12
3 > u > 4
3 < u < 12
2. Solve the compound inequality 9 + 3n 3 or 5n < 30. (1 point)
n −2 or n < 6
n −2 or n < 6
n −5 or n > 6
n −5 or n > 6
3. Solve the compound inequality 6b < 24 or 4b + 12 > 4. (1 point)
b < 4 or b > −2
b < 4 or b > 4
b < 4 or b > 2
b > 4 or b < −2

Answer 1

I need help on how to do this

Answer 2

Lol. Is that a test?

Answer 3

1. 30 < 10u < 120
Just divide all sections by 10 to get the answer of:
3 < u < 12

2. Is that missing an '=' sign, supposed to be 9 + 3n = 3 or 5n < 30?
If so 3n=-6 so n=-2 and divide both sides by 5 to get n<6
n= -2 or n < 6

3. 6b < 24 or 4b + 12 > 4
divide the left one by 6 to get: b < 4 then the right: 4b > -8 divide by 4 to get b > -2
b < 4 or b > -2
