5/12-3/8 In Simplest form can someone please break it down so I can understand how to get the answer..

jeka94

To find 5/12-3/8, you have to find a common denominator. A common denominator of 12 and 8 could be 24. So, you multiply 5/12, both the numerator and the denominator by 2, which gives you 10/24. Then, you multiply 3/8 both by 3 to get the common denominator of 24. 3/8x 3 is 9/24. So, 10/24-9/24 is 1/24 because you only subtract the numerator and keep the denominator the same.

Jean transformed a point by using the rule (x,y) (x-6, y+8). The image point is (–4, 1). Which point is the pre-image?

lubasha [3.4K]

For this case we have the following transformation:
$(x, y) (x-6, y + 8)
$
Using the transformation we have that the image is:
$(-4, 1)
$
Therefore, making use of this information, we can find the coordinates of the pre-image
We have then:
$x-6 = -4
$
From here, we clear x:
$x = -4 + 6

x = 2$
On the other hand we have:
$y + 8 = 1
$
From here, we clear y:
$y = 1-8

y = -7$
The coordinates of the pre-image is:
$(x, y) = (2, -7)
$
Answer:
A point that is the pre-image is:
$(x, y) = (2, -7)$

Nataliya [291]

Answer:

The ratio between Roberto and David is 3:11

Step-by-step explanation:

If Roberto were to have 18 cards when we start, then David would have 24. Roberto has 3/4 the amount that David has. Then Roberto gives half of his cards (9) to David. Roberto now has 9 cards and David has 33.
