Answer:
$7.52 rounded
Step-by-step explanation:
$7.20x 104.5% (or 1.045)= $7.524
rouded, $7.524 would be $7.52
If 90 equals to (x+2) and (x-6), then (x+2)=(x-6), which is impossible because 2≠-6
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
Y=-1/2x + 2
I’m pretty sure that this is the answer :))
