Hi!

To solve this, we have to cross multiply.

Cross multiplying. is when you multiply the numerator of fraction A by the denominator of fraction B, then divide it by the denominator of fraction A. The answer will be the numerator of fraction B. 

\frac{x}{5} * \frac{3}{6}
5 * 3 = 15
15/6 = 2.5
\frac{2.5}{5}

So we know that x = 2.5. We also know that when we multiply 3 * 5, or 6 * 2.5 = 15. Which would mean that the answer is

A. 6x = 15

Hope this helps!

The lovin lemonade company sells a 4 gallon jug of lemonade for $24 the sweet and sour company sells an eight pack of 1 quart bo
lbvjy [14]
One way to compare is to find the price per gallon.
$24 for 4 gallons = 24÷4 = $6 per gallon

8 pack of 1 qt bottle give you 2 gallons (4qts= 1 gallon)  So you get 2 gallons for $16
$16 ÷ 2 = $8.00 per gallon.  Sweet and Sour has the higher unit price.
Even if we compare the price per quart we will get the same answer as to who is selling it at the higher unit price.
4gal for $24 = 16 quarts for $24  ( 1 gallon = 4 qts)
$24 ÷ 16 = $1.50 each (1\frac{1}2})
vs.
 8 quarts for $16  $16 ÷ 8 = $2.00 per qt.  Sweet and sour still has the higher unit price

timofeeve [1]

Answer:

n = 6

Step-by-step explanation:

the formula for interior angle is ( n-2)

but we given the measure of one angle, so solve

720 = (n - 2)180

720/180 = (n - 2)

4 = (n - 2)

combine the like terms

4 + 2 =n

6 = n

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed.
LenaWriter [7]

Answer:

28 meters cubed.

Step-by-step explanation:

Since we know that the volume of a sphere is 4/3 the volume of a cylinder, we can multiply 21*4/3. 21*4 will equal 84 and 84/3 would be 28. So the volume of the sphere would be 28 meters cubed.
