Solve the inequality and describe the solution set.
y
–
6
≥
12
To solve the inequality, we can add 6 to both sides:
y - 6 ≥ 12 + 6
y - 6 ≥ 18
Then, we add 6 to both sides again to isolate y:
y ≥ 18 + 6
y ≥ 24
So the solution set to this inequality is all values of y that are greater than or equal to 24. We can express this solution set using interval notation as [24, ∞).

Gabriella went skiing. She paid $35 to rent skis and $15 an hour to ski. If she paid a total of $95, how many hours did she ski? Write an algebraic equation to represent the situation and solve it.
Let x be the number of hours Gabriella skied. Then we can write an algebraic equation to represent the situation:
35 + 15x = 95
To solve for x, we can first subtract 35 from both sides:
15x = 60
Then, we can divide both sides by 15:
x = 4
So Gabriella skied for 4 hours.

Solve the equation.
c
4
−
5
=
4
To solve the equation, we can first add 5 to both sides to isolate the variable term:
c/4 = 9
Then, we can multiply both sides by 4:
c = 36
So the solution to the equation is c = 36.
What is the major cause of the greenhouse effect?(1 point)
The major cause of the greenhouse effect is the increased concentration of greenhouse gases, such as carbon dioxide, in the Earth's atmosphere, which trap heat from the sun and cause warming of the Earth's surface.
