Hi!
So, to "half" a number, you multiply it by 1/2 or 0.5
"A number" is a number which we don't know the value of, so we could use a variable. Any letter you want is fine, but let's use x
"Decrease by 12" This simply means to subtract 12, so - 12
So, now we have:
1/2x - 12
Answer:
The answer is 16.
Step-by-step explanation:
6 x 3 = 18
18 - 2 =16
Answer:
0
Step-by-step explanation:
We have two points we can use the slope formula
m = (y2-y1)/(x2-x1)
= (-4 - -4)/(9-4)
(-4+4)/(9-4)
0/5
=0
Answer:
Factor of 2.
Step-by-step explanation:
The radius ( one dimensional) scale factor is the square root of the surface area (2 dimensional) factor .
√4.0 = 2.0.
