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.
Answer:
x≤-2
Step-by-step explanation:
To solve the inequality, we have to add 1 on each side:
5x-1≤11
+1 +1
And then we get:
5x≤-10.
To find x, we have to divide each side by 5:
5x/5≤-10/5
After we do that, we get:
x≤-2.
As you bring all the non-variable numbers over to the right side, it becomes 384 which you then will divide the 32 in x which gives us 12. so x=12
Well if I am reading this right the question is 9000 divided by 1/2 which would basically equal to 9000 times 2. The answer is 18000.
(i) Slope is 
(ii) x - intercept is 
(ii) y - intercept is 
Explanation:
The given equation is 
We need to determine the slope, x - intercept and the y - intercept
(i) Let us determine the slope of the equation.
Since, the equation is of the form 
where m is the slope
Thus, comparing the equation with the general form , the slope is 2.
Thus, slope is
(ii) Now, we shall determine the x - intercepts.
The x - intercept can be determined by substituting 
in
Thus, we have,
Thus, the x - intercept is
(iii) The y - intercept can be determined by substituting 
in
Thus, we get,
Thus, the y - intercept is
