      Hey there! Have you heard about sin? Basically, it is anything that is wrong that we do to upset God. Sin upsets God because He is Holy. Just like this( Imagine if you saw someone being robbed!) God does not like sin, and Heaven is His God's home. So imagine you are sinning and trying to enter into God's house! What happens is, you OWN'T end up in God's House! Basically, you end up in Satan's, the creature who is decieving souls into going to his house, hell, which will be his permanent residence in a few years, where he wants to take millions of souls including yours! There is no second chance when you gte into hell. It is jail, but aint no bail". And that's why Jesus died. He died in our place, that we might just have a chance at life if we believed in Him. Repent of your sins and believe in Him!.

      You need to hear this:
      Matt 21:37 But as the days of Noah were, so shall also the coming of the Son of man be. 38 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark, 39 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
      8 people were saved...
      THE MILLION-DOLLAR QUESTION: Will you go to Heaven when you die? Have you lied, stolen, used God’s name in vain, or lusted (which Jesus said was adultery, (Matthew 5:28)? If so, God sees you as a liar, thief, blasphemer, and adulterer at heart. If you die in your sins, you will end up in a terrible place called Hell. But there's good news. Though we broke God's Law, Jesus paid the fine by dying on the cross: "God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life" (John. 3:16). Then Jesus rose from the dead and was seen by hundreds of eyewitnesses. He fulfilled all the prophecies of the promised Savior. Please, today, repent and trust Jesus, and God will forgive you and grant you the gift of eternal life (Ephesians. 2:8-9).

      @lolliz100 2 роки тому +2

      Yea he went through a complicated route...for that Number 1, (b) iii.... Which happens at times when the brain misses the obvious route.
      The better route would have been for him to recognise that the 24 additional oranges was because of the additional 1 proportional part that oranges had over bananas and equate the extra 1 proportional part with the 24, then just times by two to get the 48.
      Probably was just a slip on his part of him missing the more obvious route.

    WHERE YOU GET K FROM QUESTION 2C

    • @maryyuhh
      @maryyuhh Рік тому

      the letter k represents the constant of proportionality that relates the two variables.
      When two variables are said to vary directly with each other, it means that when one variable (x) increases or decreases, the other variable (y) increases or decreases in proportion to x. Mathematically, we can express this relationship as y = kx, where k is a constant value that remains the same as x and y change.
