Number of servings = 8 1/4 ÷ 3/4
= 33/4 ÷ 3/4
= 33/4 × 4/3 = 11
= 11 servings.
Let w represent weight here. Then 0.05w = 300 lb.
300 lb
Solving for w, w = ------------- = 6000 lb (3 tons)
0.05
Answer: Choice C
The solution is
The graph has an closed filled in circle at 8 on the number line, with shading to the right of that closed circle.
=======================================================
Explanation:
see note below
note: I divided both sides by -4 to undo the multiplication done to z; the inequality sign flips because we divided both sides by a negative number
So the solution set is the set of z values such that z is 8 or larger. We are including the endpoint 8 so we use a filled in closed circle (not an open circle or hole). We include the endpoint because of the "or equal to" as part of ht inequality sign.
