Answer:The reason there is no commutative property for subtraction or division is because order matters when performing these operations.
Step-by-step explanation:
Given:
The values are .
To find:
The values of and .
Solution:
We have,
...(i)
Multiply both sides by 10.
...(ii)
Subtracting (i) from (ii), we get
And,
Now, the product of a and b is:
The quotient of a and b is:
Therefore, the required values are and .
Answer:
A. 600
B. 565.2
C. 8000
D. 8125.376
Step-by-step explanation:
Rounding up from 500 is 600 (Nearest HUNDRED)
Rounded up from 565.234 is 565.2 (NEAREST TENTH)
Rounded down from 8125.3758 is 8000 (NEAREST THOUGHAND)
Rounded up from 8125.3758 is 8125.376 (NEAREST THOUSANDTH)
If R is the midpoint of PS, then PR = RS -- (1)
Also, PR + RS = PS -- (2)
__________________
PR + RS = PS
7x + 23 + 13x - 19 = PS
__________________
Now, PR = PS
7x + 23 = 13x - 19
7x - 13x = -19 - 23
-6x = -42
x = -42/-6
x = 7
__________________
PS = 7x + 23 + 13x - 19
PS = 7(7) + 23 + 13(7) - 19
PS = 49 + 23 + 91 - 19
<u>PS </u><u>=</u><u> </u><u>1</u><u>4</u><u>4</u><u> </u>
Hope it helps!

Okay so we get: subtract m + 8 from 5m + 11
5m + 11 = 16 + m or 16m
16m - 8 +m or 8m = 8m or 8 + m
