For any values less than -3, the answer is undefined, because then you have a negative value for √x+3
To find this, turn the word question into an equation.
"One less than" means - 1, which is 1 being subtracted from something.
"half a number" means 1/2x, since 1/2 is half and x is unknown.
"is 12" means = 12, which is something equals 12.
Putting this in order would be 1/2x, then - 1, then = 12.
As an equation, this is 1/2x - 1 = 12.
So the equation is 1/2x - 1 = 12
Now you must find the number by solving this equation.
1/2x - 1 = 12
First, add 1 to both sides.
12 + 1 = 13
1/2x = 13
Now multiply both sides by 2.
This way, x will be isolated since 1/2x • 2 = 1x, and 1x = x.
13 • 2 = 26
x = 26
The number is 26.

Step-by-step explanation:
7. 1250 - 1050 = 200 remaining. so $ 200 split evenly between savings and entertainment.....means each gets $ 100.
what percent of her monthly budget will go towards savings ?
100 / 1250 = 0.08 = 8% <==
==================
luke spent 300 of his 375...
what percent did he not use...
(375 - 300) / 375 = 75/375 = 0.2 = 20% was not used <==
