Question 1 |

Evaluate 3x7+4-6Ã·3-7+45Ã·5x4+49

101 | |

103 | |

99 | |

35 |

Question 1 Explanation:

21+4-6Ã·3-7+45Ã·5x4+49 (Dividing)

21+4â€“2â€“7+9 x4+49 ( Multiplying )

21 +4 -2 -7 +36 +49( Addition )

25 -2-7+85 ( Subtracting )

110-9 = 101

21+4â€“2â€“7+9 x4+49 ( Multiplying )

21 +4 -2 -7 +36 +49( Addition )

25 -2-7+85 ( Subtracting )

110-9 = 101
