The Directions is "Use the product rule to simplify the following monomials.
Step-by-step explanation:
about your question I'll just put it in the comment section:)
Answer:
PR5T represents <em>6754.</em>
P = 6
R = 7
T = 4
Y = 5
Step-by-step explanation:
Let us try to understand the subtraction starting from the unit's digit.
P R 5 T
- 4 7 Y 6
-----------------
1 9 9 8
To get 8, 6 should be subtracted from 14
14 - 6 = 8
So, T should be equal unit digit of 14 <em>i.e.</em> T = 4 and 1 should be carried over from the ten's digit of PR5T.
Now, let us move to ten's digit:
P R 5 4
- 4 7 Y 6
-----------------
1 9 9 8
To get 9, 6 should be subtracted from 15. But 1 is already carried to unit's place So, we have actually 14 here
14 - Y = 9
So, Y = 5
Moving to hundred's place:
R - carry - 7 = 9
Carry is 1, so R = unit's place of 9 + 8 i.e. R = 7
Moving to thousand's place:
P - carry - 4 = 1
Here carry is 1
So, P = 1 + 4 + 1 = 6
So, the number PR5T is <em>6754.</em>
Answer:
20x + 15 = 11
Step-by-step explanation:
First you need to add the like terms:
-7+2=-5
Now you need to expand the brackets:
-5*-4x=20x
-5*-3=15
Now you have 20x + 15 = 11. So if you want you can rearrange the formule to find x.
20x=-4
x= -5
The inequality I believe is 3(n-2) >5n
P.S Make sure to put a line under the inequality sign to represent greater than or equal to ;)
