9a-2b=-8.....1
-7a+3b=12.....2
So,
1 equation into 3 and 2 equation into 2.
Then,
18a-6b=-24
-14a+6b=24.
4a=0 a=0 .
Substitute a value in 2 equation.
b=4.
Hope it helped
The statements aren't given; however the number of 1/2 and 1/4 - pound package have been calculated below.
Answer:
Step-by-step explanation:
Given :
A 12 pound block :
Number of 1/2 pound packages that can be obtained :
12 ÷ 1/2 ;
12 * 2/1 = 24 (1/2 - Pound package) can be obtained.
Number of 1/4 pound package that can be obtained :
12 ÷ 1/4
12 * 4 /1 = 48 (1/4 - Pound package) can be obtained
We can obtain twice the number of 1/2 - pound package by using the 1/4 - pound slicing.
Note: On the unit circle, P (x, y) = (cos(t), sint(t))
Terminal point of t = 10pi/3 is <span>( -1/2, -sqrt(3)/2)</span>
Answer:
3rd Option is correct.
Step-by-step explanation:
Given Equation:
x² - 16x + 12 = 0
First We need to find solution of the given equation.
x² - 16x + 12 = 0
here, a = 1 , b = -16 & c = 12
Now,
Option 1).
( x - 8 )² = 144
x - 8 = ±√144
x - 8 = ±12
x = 8 + 12 = 20 and x = 8 - 12 = -4
Thus, This is not correct Option.
Option 2).
( x - 4 )² = 4
x - 4 = ±√4
x - 4 = ±2
x = 4 + 2 = 6 and x = 4 - 2 = 2
Thus, This is not correct Option.
Option 3).
( x - 8 )² = 52
x - 8 = ±√52
x - 8 = ±2√13
x = 8 + 2√13 and x = 8 - 2√13
Thus, This is correct Option.
Option 4).
( x - 4 )² = 16
x - 4 = ±√116
x - 4 = ±4
x = 4 + 4 = 8 and x = 4 - 4 = 0
Thus, This is not correct Option.
Therefore, 3rd Option is correct.
A right triangular prism is a solid that has faces that consist of 2 equilateral triangles and 3 congruent rectangles. It is also described to have two parallel faces, and 3 other faces that belong to the same place (and are not parallel to the parallel pair of faces).
