Question

8.5+4(1-2.5k)=24.5 round to the nearest hundredth

2 Answer

  • Hi there! 

    Your question: 

    8.5 + 49(1-2.5k)=24.5

    My answer: 

    8.5 + 4(1-2.5k) = 24.5 >>>>>>> first, you have to distribute

    8.5 + 4 - 10k = 24.5 >>>>>>>> now, we are going to combine like terms.

    12.5 - 10k = 24.5 >>>>>> now, we are going to subtract 12.5 on both sides 

    -10k = 12 >>>>>>>>> finally, divide -10 on both sides

    k = -1.2


    Hope this helps you!


  • Your Problem:
    8.5+4(1-2.5k)=24.5
    1st step: subtract 8.5 from both sides
    4(1-2.5k)=24.5-8.5
    4(1-2.5k)=16
    2nd step: Divide both sides by 4
    (1-2.5k)=16/4
    (1-2.5k)=4
    3rd step: Opening up the parentheses
    1-2.5k=4
    4th step: Subtract 1 from both sides
    -2.5k=4-1
    -2.5k=3
    4ht step: divide both sides by -2.5
    k=-1.2
