A solution to the inequality 3.75 – 3x ≤ 6.
LenKa [72]

Answer:

x ≥ -0.75

- 3x ≤ 2.25

Divide both sides with -3.

x ≥ 2.25/-3

x ≥ -0.75

A class voted for either rollerblading, swimming, or biking as their favorite summer activity. If rollerblading got 27% percent
emmasim [6.3K]

Answer:

All you have to do is find the rest of the percentage. Percentage adds up to 100%. So you will have to add the two percentages they gave you. 27+33=60%. Now you have to take away 60 from 100. 100-60=40%.

40%- That's the answer.

Hope this helps.
