A packed box that is being shipped will be weighed in order to calculate the correct postage needed. The total weight of a packe
marishachu [46]

Answer: 6.36lb

Step-by-step explanation:

Step-by-step explanation:

Total Weight of the package = weight of product + weight of box

Weight of empty box =0.88lb

Total weight of the box is =7.24lb

Let Weight of product inside box=w

Let wet of empty box =y

Total weight = F

Then,

F=y+w

Since F=7.24lb. y=0.88

Then, w=F-y

w=7.24-0.88

w=6.36lb

The weight of the product is 6.36lb

hope this helps :)

What is the algebra phrase x time y equal
Alexxandr [17]

Answer

x times y = xy

x + y times a + b = (x + y)(a + b)

For that you can use the FOIL method which is First, Outside, Inside, Last.

First: x times a = ax

Outside: x times b = bx

Inside: y times a = ay

Last: y times b = by

So you have ax + bx + ay +by.

If you end up using numbers, then you can simplify.

Ask your teacher or parents. It's easier to explain in person.
