-30x + 16. You use the distributive property to get -24x + 28 -12 -6x. Then combine like terms to get -30x + 16.
Answer:
3 bottles
Step-by-step explanation:
area=base x height
area=30 x 15=450 ft^2
450/180=2.5
Your answer is D. 36 - 8i

That would be: <span>how many rolls add up to 2,3,4,5? </span>
<span>There are 36 possible rolls.</span>
To solve this problem, we can write an equation letting the variable x represent the number of bottles in a box of water (this means that the expression x-1 represents the boxes that have one fewer bottle than a full box).
This allows us to create the following equation:
9 original bottles + 3x (3 full boxes) + 2(x-1) (two boxes with one fewer bottle) = 67 total bottles
OR
9 + 3x + 2(x-1) = 67
Now, we can begin to solve this equation by using the distributive property to get rid of the parentheses on the left side of the equation.
9 + 3x + 2x - 2 = 67
Next, we can combine like terms on the left side of the equation (meaning add the variable terms together and subtract the constant terms).
7 + 5x = 67
Now, we should subtract 7 from both sides of the equation to get the variable term alone on the left side of the equation.
5x = 60
Next, we should divide both sides by 5 to isolate the variable x on the left side of the equation.
x = 12
Therefore, your answer is that there are 12 bottles in a full box.
Hope this helps!
