Multiplying both sides of <span>−1/3x≤−6 by -3 results in "x is equal to or greater than 18."
Note that multiplying such an inequality requires reversing the direction of the inequality symbol.
I subst. 18 for x in </span><span>−1/3x≤−6 as a check, and found that the resulting inequality is true.</span>

Answer:
1 solution
Step-by-step explanation:
The coefficients of d are different on the two sides of the equation (3d vs 6d), so the equation has one solution.
__
Dividing by 3 gives ...
d +11 = 2(d +33)
d + 11 = 2d + 66
Adding -d-66 to both sides gives ...
-55 = d . . . . . . the one solution
To simplify this expression, you have to distribute. Distribution is when you multiply the outside number by the inside ones. For example, if I distributed 2(4 + 6), I would get (2 × 4) + (2 × 6).
So if we distribute your expression, we'd get:
(-3 × -4y) + (-3 × 3) + 7y
Now simplify:
12y + -9 + 7y
Once more, simplify:
19y - 9
The answer is A
The correct answer would be D. You find the range by subtracting the lowest value of a data set from the highest value of the data set.
