Step-by-step explanation:
<u>Step 1: Define</u>
(5x + 3) - (2x - 6)
<u>Step 2: Simplify</u>
- Distribute negative: 5x + 3 - 2x + 6
- Combine like terms (x): 3x + 3 + 6
- Combine like terms (Z): 3x + 9
Answer:
.6%
Step-by-step explanation:
You get this by dividing 3000 from 18. 18/3000=.006 then to make it a decimal you move the point 2 spaces to the right.
It is a reduction of the original because it became a smaller figure. The scale factor would be less than 1 because it is shrunken I would say the scale factor is 1/2
Set up a proportion
3 coins:8 notes and then the other one 24 coins : x (unknown notes)
they have a relationship so we can set them equal to each other.
3/8=24/x cross multiply: 8 * 24 = 192
Now divide that by 3: 192/3 = 64
So there are 64 notes in the bag
