10x + 6

Step-by-step explanation:

When distributing, you need to multiply the number on its own by both terms of the binomial (the 5x + 3). 5 times 2 is 10, and then you have the x, so it is 10x. Multiply 3 times 2 and get 6. Hope this helps!

As a sum of two terms, is, 10x + 6

I'm pretty sure that the answers would go, Wrong, increased, 9 1/2 points, 6 5/8 points, dropped, 12 3/4 points.

Step-by-step explanation:

The reason why it would be wrong is because the amount of points lost was less than the total amount of points gained.

In week one and two the company gained 9 1/2 points and 6 5/8 points. When you add them together, you get 16 1/8 points.

In week three the company lost 12 3/4 points. If you multiply the fraction to change the denominator to 8, the mixed fraction becomes 12 6/8.

16 1/8 - 12 6/8 = 3 3/8

As you can see, there are still points left over.

In the fourth week, they ended up losing all of their points and then some more, but from my understanding it's just asking about the third week.

Answer:

Since 10 to the ninth power is 1000000000 and 1000000000 times 1.4 is 1400000000 and 10 to the second power is 100 and 100 times 8.25 is 825 you would subtract 1400000000 and 825 and get the answer of 1399999175.

*this might be wrong*

1.4*10 2nd power = 1400000000
8.25*10 2nd power = 825
1400000000*825= 1155000000000

If 33% of people chose vanilla and 19% chose chocolate as their favorite flavor of ice cream, what percent of people chose a flavor other than vanilla or chocolate

Answers

Answer:

the percentage has to be out of hundred and since 52% is taken up (33+19) 48 is the left over percentage

48%

Well the most a Percentage can go to is 100%

We know :

Now, Subtract the total percentage from the total number of people that voted for Chocolate AND Vanilla:

100 - 52 = 48

Final Answer: 48% chose a flavor other than Vanilla or Chocolate.

Hope this Helps!
