It is never less than 1 because if it's an improper its a whole combined into the little part so a whole times a whole is always a whole whether it has a small part too or not
Answer:
21
Step-by-step explanation:
Substitute.
We are given x = 3, y = 9 and z = 2
3(9-2) = 3(7) = 21
Answer:
Purchases greater than 66.67 dollars should use coupon 2, while purchases between 20 dollars and 66.67 should use coupon 1.
Step-by-step explanation:
Coupon 1 must be used as long as those 10 dollars represent more money than 15% of coupon 2.
For example, if the purchase is the minimum of $ 20, 10 dollars represents half of the purchase, therefore in this case it is better to use coupon 1.
In this case, coupon 2 would only be a discount of 3 dollars (20 * 0.15).
So when from what value would it be better to use coupon 2, it would have to be calculated when it is worth more than 10 dollars.
10 = x * 0.15
x = 10 / 0.15
x = 66.67
That is to say that from the purchases greater than 66.67 dollars, coupon 2 would have a discount equivalent to 10 dollars or more.
The volume of a pyramid is expressed as the product of its length, width and height divided by three. We first solve the volume of pyramids A and B.
Volume of A = (10 x 20 x h) / 3 = 200h / 3
Volume of B = (10 x 10 x h) / 3 = 100h/3
Since the heights of the two pyramid are the same we can substitute on equation to the other in terms of h.
Volume of A = (200 x 3 x Volume of B) / (100 x 3)
Volume of A = 2 x Volume B
Thus, the volume of A is twice the volume of B.
If the height of pyramid B is twice of pyramid A, the new volume of pyramid B is equal to the volume of pyramid A.
Answer: x=4 is a solution because if you divide both 56 and 16 by 4, you get 14/4
