X = 42
x/3 - 4 = 10
+ 4 +4
x/3 = 14
•3 •3
x = 42
The level of precision is given by the number of decimal places.
1.45 has a precision of 2 ( two decimal digits)
.0034 has a precision of 4 ( 4 decimal digits)
Numbers that end in zeros have negative precision:
100: has a precision of -2 ( 2 zeros)
15 : Whole numbers has precision 0.
From most precise to least precise:
.0034 - 1.45- 15 - 100
Answer:
Infinitely many solutions.
Explanation:
In this case we gonna use ELIMINATION BY ADDITION method.For that first we are gonna eliminate the terms containing ( X ).
Equation no 1:
3x + 3y = 10
Equation no 2:
-9x - 9y = -30
Now multiply equation no 1 with (3 )
3(3x + 3y) = 3(10)
9x + 9y = 30 ( equation no 1 )
Now ADD both the equations
9x + 9y = 30
<u> -9x - 9y =-30</u>
0 = 0
