**Answer:**

**Step-by-step explanation:**

The** sum of 38 **and **twice a number x **is 124. The value of "x" is** 43**

**- 2x - 5** is equal to** – 91.
**

<u>**Solution:**</u>

Given that , The **sum of 38 and twice a number** x is 124.

We have to find what is - 2x - 5?

Now, according to given information, 38 + 2 × x = 124

2x + 38 = 124

2x = 124 – 38

2x = 86

x = 43

So, the value of **x is 43**

<em><u>**Now, Evaluating - 2x – 5 **</u></em>

Substitute "x" = 43 to evaluate

- 2(43) – 5

- 86 – 5 = - 91

Hence, the required answer is **– 91.

**Answer:**

It should be $13 for one pair of socks.

**Step-by-step explanation:**

Similar triangles, so 24/32=33/32+x. cross multiply to find that 32*33=24(x+32). this gives you 1056=24x+768. subtract 768 from both sides to get 288 = 24x. divide both sides by 24 to get x=12
