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.

Tomtit [17]

Answer: There are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.

Step-by-step explanation:

Since we have given that

Number of sections = 3

Number of rows in each sections = 3

Number of square pieces in each row = 15

So, the number of squares that will be in the completed quilt would be

3\times 3\times 15\\\\=9\times 15\\\\=135

Hence, there are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.
