12.5 x10^7
To multiply by 10^7, move the decimal 7 place values to the right and fill in with all necessary zeros.
Final answer: 125,000,000
6 to the second power means 6²
So,
6² ÷ 2 ( 3 ) + 4
=36/2(3)+4
=(18)(3)+4
=54+4
=58
It’s the same now in decimals is 2.35215804 it goes on
There are infinitely many solutions for x, y and z.
By elimination, we have
(2x + 3y + 4z) - 2 (x + y + z) = 100 - 2•30
⇒ y + 2z = 40
and
(2x + 3y + 4z) - 3 (x + y + z) = 100 - 3•30
⇒ -x + z = 10
If we let z = t for some real number t, then
y + 2z = 40 ⇒ y = 40 - 2t
-x + z = 10 ⇒ x = t - 10
so any solution to the system is a point belonging to the set
