Step-by-step explanation:
The scale factor is the ratio of corresponding sides, image to original, thus
scale factor = 
= 
, then
x = × 9 = 2 × 3 = 6
y = × 7 = 
The answer for this problem mia 102
Mean = 40 median = 37.5 mode = 30
12 - x = 20 - 5x
You see that -x and -5x both have an 'x' variable? This means they are 'like' terms. To get -x to the other side, we must add (if like terms are on opposite sides, do the opposite of what the sign says, e.g. - will be +)
12 = 20 - 4x
Now move 20 to the other side. Remember, do the opposite! Since 20 is positive, we must minus 20 to the other side.
-8 = -4x
To get x by itself, you will need to get rid of the coefficient of -4. -4x basically means -4 times x, so the opposite of that would be divide! Divide by -4
2 = x (Since both sides have a negative, they cancel out to give a positive)
x = 2
Answer:
4,847.2
Step-by-step explanation:
$8×30=$240
$240+3%=247.2
$4,600+247.2=4,847.2
