Jamal lives 8 blocks from school. Bethany lives 3 times as far from school as Jamal . Michael lives 4 times as far as Jamal and Bethany combined . Write a number sentence that compares how far from school Bethany lives to how far from school Michael lives.

Q2/ if you multiply both sides of an equality by 8 do you still have an equality? Give an example.

Q3/ Evaluate the expression (12_4)*(2+1). Would the value change if there were no parentheses?

I don't know..

  1. b = 3j
    m = 4(b+j)
    m = 4b+4j
    m = 4b+4(b/3)
    m = 16/3 b

    yes
    3 = 1+2
    3*8 = (1+2)*8 = 8+16 = 24

    (12-4)*(2+1) = 8*3 = 24
    12-4*2+1 = 12-8+1 = 5
    in the absence of parens, multiplication is done before addition.

    That's why 3x+2 is (3*x)+2 and not 3*(x+2)
