The sum of half a number and 5 is 9. what is the number? solve this equation: d/4 - 9 = -3

Hello there! The number is 2, and the solution to the given equation is d = 24.

Let's start by finding what the number is. To do this, let's analyze the information we are given.

The sum of half a number and 5 is 9. ⇒ We know we are adding.

The sum of half a number and 5 is 9 ⇒ We are adding 0.5n and 5.

The sum of half a number and 5 is 9 ⇒ The solution is equal to 9.

So, let's solve: 0.5n + 5 = 9 by isolating n.

0.5n + 5 = 9

0.5n = 4

n = 2.

So, our number is equal to 2.

Now, let's solve the equation! (We are working to isolate d.)

d/4 - 9 = -3

d/4 = 6

d = 24.

I hope I could help you and have a great rest of your day!

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
