$\sqrt{x - 5} + 7 = 11$

$(\sqrt{x-5}) ^{2} = (4)^{2}$

|x - 5| = 16

x - 5 = +/- 16

x - 5 = 16 or x - 5 = -16

+5 +5 +5 +5

x = 21 or x = -11

Answer: x = {21, -11}

What strategy can be used to solve 8 x 25 x 23

wariber [46]

The best way to multiply complicated problems mentally* is to break them into chunks.

Start with 20 times 8 to get 160, and then 8 times 5 to get 40. Add these together to get 200. 200 times 3 is 600, and 20 times 200 is 4000. Add these together to get your final answer, 4600.

In other words 8 x 20 + 8 x 5 = 200 200 x 3 + 200 x 20 = 4600

*I assumed you meant mentally, because otherwise you'd just multiply longhand, multiplying two of the three numbers and then multiplying their product with the third.

Write an inequality that represents the description then solve; Max has more than 5 carrots ( number of carrots Max has = c)

torisob [31]

If "C" is the number of carrots, then the phrase "Max has more than 5 carrots" can be written like this:

$c\ \textgreater \ 5$ : the number of carrots that Max has is bigger than 5.

However, we can't solve it without any additional information, all we know is that $c\ \textgreater \ 5$
