Answer:

We have been provided the number, 3430000. Therefore, the standard form is, 3430000=3.43×106, here, we have moved 6 places to the left. Hence, the standard form of 3430000 is 3.43×106. Note: It is important to note that the standard form of representing numbers is also called scientific form or standard index form.

Answer:

it is a simultaneous equation and I used Elimination method

$2x + 8y = 18(equ \: 1) \\ y = - x + 6 \: \\ y + x = 6 \: (equ \: 2) \\ \\ from \:( equ2) \\ \: x = 6 - y \: (equ \: 3 )\\ sub. \: (equ3) \: in \: (equ2) \\ 2(6 - y )+ 8y = 18 \\ 12 - 2y + 8y = 18 \\ 6y = 18 - 12 \\ 6y = 6 \\ \frac{6y}{6} = \frac{6}{6} \\ y = 1 \\ \\ sub. \: y \: in \: equ3 \\ x = 6 - y \\ x = 6 - 1 \\ x = 5 \\ \\ \\ y = 1 \: \: x = 5$
