Explain the difference between four times the sum of X and Y and the sum of four times X and Y
tester [92]

Answer:

Condition 1:

four times the sum of X and Y = 4(X + Y)

Condition 2:

the sum of four times X and Y=  4X + Y

  • Difference:

        In condition 1, both the variables are first added and then multiplied by        four. This can be simplified as:

                   4X +4Y

I condition 2, only the variable X is multiplied with 4 and then added to Y.

  • Conclusion:

         With positive integers, condition 1 will always give a greater value.

         With negative integers, condition 2 will have greater value.

I hope it will help you!

darcy likes to eat peanut butter and raisins on apple slices. on each apple slice she puts 1/16 cup of peanut butter and 8 raisi
netineya [11]
The answer is 7/10.

For one apple slice, Darcy needs 1/16 cup of peanut butter and 8 raisins. She has 2/5 cup of peanut butter. To compare how many butter she has and she needs we will divide 2/5 with 1/1

This means that Darcy needs 5/80 cup of peanut butter <span>and 8 raisins.
If she has 32/80 cup of peanut butter, she will have it only fo 6 or 7 apple slices (32/80 </span>÷ 5/80 = 6.4) depending how it is rounded. If she prepares 6 apple slices, she will still have a little of peanut butter left (0.4 = 2/5 of cup). So, she will prepare 7 apple slices so the butter will be all gone.

For 7 apple slices, she needs 56 raisins (7 × 8 raisins).
That is 56 raisins out of 80 raisins, so <span>fraction of the 80 raisins did she eat is:
</span><span>\frac{56}{80} = \frac{7}{10}</span>
