Not sure what you're asking, but if it's a T/F question, the answer would be false.

Hope this helped, and if it did I'd appreciate if you marked me as brainliest as I need it to get to a higher rank.

at a grocery store, an uncooked beef roast is on sale for $5.99/lb. At the same grocery store, prepared roast beef is available

-Dominant- [34]

Answer:

$7.58/lb

Step-by-step explanation:

raw roast: $5.99 per lb

deli roast: $2.99 for 100g

We know the price per lb of the raw roast.

Let's find the price per lb of the deli roast.

1 lb = 454 grams

454 grams / 100 grams = 4.54

1 lb is 4.54 times 100 g

If we multiply the price of 100g of deli roast by 4.54, we get teh price per lb.

$2.99/lb * 4.54 = $13.57/lb

raw roast: $5.99/lb

deli roast: $13.57/lb

difference in price of 1 lb: $13.57 - $5.99 = $7.58

Answer: $7.58/lb

I’m having trouble here can somebody help ASAP.

6x + 4 - x = 2(x+1)

First combine like terms on the left side:

6x-x - 5x

So you have 5x+4 on the left side.

Then use the distributive property on the right side:

2(x+1) becomes 2x +2

Now you have 5x +4 = 2x +2

Subtract 4 from each side:

5x = 2x -2

Subtract 2x from each side:

3x = -2

Divide both sides by 3:

x = -2/3
