Answer:

x=8

Step-by-step explanation:

In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 7, you get 23.

To solve this, you first write the problem as an algebra equation as follows: 2x + 7 = 23

Then you solve the equation by subtracting 7 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 7 = 23

2x + 7 - 7 = 23 - 7

2x = 16

2x/2 = 16/2

x = 8

Explain why 7* 6 x 5 x 4*3*2*1+5 is a composite numbers

xenn [34]

Answer:

7×6×5×4×3×2×1+5 can be written as 5*[7*6*5*4*3*2*+1] or 5*(1009). So, other than the number and 1, it has 5 and 1009 as its factors too. So it is a composite number.

Step-by-step explanation:

A composite number is a positive integer that has a factor other than 1 and itself.
