Answer: 21
Step-by-step explanation: To solve this problem, we can first set up a proportion because we know that 3 is to 7 as 9 is to x.
So we have 
.
Now, we can use cross products to find the missing value.
So we have 3 time x which is 3x and 7 times 9 which is 63.
Rewriting our equation, we have 3x = 63.
Dividing both sides by 3, we find that <em>x = 21</em>.
So, <em>x = 21</em>.
The red arrows in the middle mean that they are parallel so the slopes are the same.
First we must know 40 percent is equal to 0.4
Since sales were up 40 percent in addition to the 100 percent it must have originally we can mustiply 300,000 by 1.4,
After doing this operation the correct anser is 420000
There are 16 oz per pound, so that 4 oz is equal to 4/16 or 1/4 pound.
Since each box contains 10 packages and each package weighs 3 lbs 4 oz which is equivalent to 3-1/4 lbs , then the weight of each box will be
(10 (3-1/4) = 32-1/2 pounds per box
The weight of 4 boxes will then be (4 boxes) (32-1/2 pounds per box) = 130 pounds.
