4x -3y + z = -10...............(1)
2x +y + 3z = 0...............(2)
-x +2y - 5z = 17...............(3)
First we multiply 3*(2) and add it to (1)
6x +3y +9z =0..................+(1)..................> 10x + 10z = -10......(4)
Then we multiply -2*(2) and add it to (3)
-4x -2y -6z =0 ...................+(3)................> -5x -11z = 17...........(5)
Multiply 2*(5) and add it to (4)
-10x -22z = 34...................+(4).................> -12 z = 24 ..............>>> z = -2
Substitute z in (4)............> 10x +10(-2) = -10.............................>>> x = 1
Substitute x and z in (2).....> 2(1) +y + 3(-2) = 0..................>>> y = 4
Solution (x,y,z) = (1,4,-2)
p% × 60 = 15
p/100 × 60 = 15
6p = 150
p = 25
therefore value of p is 25
Answer:
y=2
Step-by-step explanation:
advgdsfh usb hey do f ft h
which means the sum of the 100 numbers must be
The circumference of a circle is the diameter times pi. So, 66 ft = pi x d. 66 divided by pi is roughly 21, so the diameter is 21 ft. 21 + 4 = 25. 25 x $0.45 = $11.25
