Find x in the equation: 2x + 9 = 5x - 12

Mathematics
1 answer:
Olegator [25]3 years ago
7 0

Answer:

x = 7

Step-by-step explanation:

Add 12 to both sides:

2x + 9 = 5x - 12

2x + 21 = 5x

Subtract 2x from both sides:

21 = 3x

Divide each side by 3:

7 = x

So, x = 7

What is the difference between the largest prime number less than 5o and the smallest comoosite number greater than 10
erastova [34]
<h3>Answer:  35</h3>

A prime number is one where the only factors are one and itself. A composite number has other factors.

You'll have to look at the list of numbers from 1 to 50

In that list, 47 is the largest prime less than 50, and 12 is the smallest composite number greater than 10.

So 47-12 = 35
