Answer
given radicals
convert them into simplest radical form
a) √49
√49 = \sqrt{7\times 7}
= 7
b) ∛40
∛40 = ![\sqrt[3]{2\times 2\times 2\times 5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%5Ctimes%202%5Ctimes%202%5Ctimes%205%7D)
= 2 ∛5
c) √242
√49 = \sqrt{2\times 11\times 11}
= 11 √2
hence the number are converted into simplest radicals or rational form.
the coefficient in the expression is x
Answer:
To answer the problem above we let x be the number of people who prefers salad and y be the number of people who chose steak. For lunch they will be spending $41. That is,
7x + 10y = 41
Now, for dinner they will be spending $51. That is,
9x + 12y = 51
The values of x and y from both equations are 3 and 2, respectively. Therefore, 3 people will choose a salad
To find the full bags of mulch you divide 77.5 by how much can fit in one bag (2.25). There are 34 full bags. Multiply 34 by the price per bag, which is $2.25. The total price of all 34 bags is $76.50.
