Divide the paper which is 21 inches (12+9) by 1.5 and you have your answer which is 14
Answer: 15
a=5, b=3
3a= 3x5= 15
<h3>
Answer: Choice C) (x-4, y)</h3>
Explanation:
We have x = 5 turn into x = 1. We need to subtract 4 from the x coordinate to get this. Therefore x turns into x-4.
The y coordinate stays at y = 2 the entire time, so y isn't altered. We have y map to y.
Overall, the rule is 
which translates the point 4 units to the left.
You want to break this down.
“5 less than” means you’ll subtract 5 from something.
That something is “3 times a number.” “3 times a number” means 3•x or 3x, since we’ll use x for that unknown number.
So, “5 less than 3 times a number” means “subtract 5 from 3x”: 3x-5
“Is” means “equals”. So 3x-5= something.
7, well, that’s 7.
So “5 less than 3 times a number is 7” means ”subtract 5 from 3x and set that equal to 7.”
3x-5=7
