At a grocery store, an uncooked beef roast is on sale for $4.99/lb. At the same store, prepared roast beef is at the deli for $2
Mrrafil [7]
For us to find out how many times more expensive is the deli roast compared to the uncooked roast we need to change the units;
cost of 100g=0.221lb is $2.99
cost of 1 lb will therefore be:
1/0.221*2.99
=$13.53/lb
therefore the number of times more expensive the deli roast is compared to uncooked roast is:
[price of 1lb roasted meat]/[price of 1 lb uncooked meat]
=13.53/4.99
=2.7 times

What step is wrong -12=4(f-6) step 1 12=4f step 2 4=f step 3
kirza4 [7]

Answer:

Step(iii)

The value of 'f' = 3

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given  - 12 = 4(f-6)

 Multiply  

          - 12 = 4 f - 24

<u><em>Step(ii):-</em></u>

- 12 = 4 f - 24

Adding '12' on both sides, we get

- 12 + 12 = 4 f - 24 + 12

     0 = 4 f - 12

     4f - 12 =0

    4 f = 12

<u><em>Step(iii):</em></u>-

Dividing   '4' on both sides, we get

    f = 3

28=-4 (2x+7) what does x equal
Alecsey [184]
Well first lets do the distributive property so the left side is already done 28, now the right side -4 (2x+7) when you do that you get -8x-28. So now we have 28=-8x-28. So now I would move the -28 to the left side and when you move stuff to the other side you change the sign so the sign will be positive 28+28 which is 56. Now you have 56=-8x. Now divide both side by -8 to have -7=x

Your Answer: x = -7
