Answer:

A. -102 + 25.5.

Step-by-step explanation:

After multiplying 51 by -2.0, you will get -102. When multiplying 51 by -0.5, you get 25.5. A is the next step in this equation. (Optional answer: read this when this is also in your quiz. -102 + 25.5 = 127.5).

Answer:

no b is the correct answer

Answer:

Step-by-step explanation:

im pretty sure its b

Step-by-step explanation:

First you need to change the mixed fractions into improper fraction which is 38/6 and the other fraction turns into 3/2 now since the question was about multiplying we multiply. So there are numbers that can be reduced like 3 divided by 6 and 38 divided by 2. So now that there are simpler nmbers that cannot be reduced more we multiply and we get 19/2 which if you wanted as a mixed fraction is 9 and 1/2.

First, find the percentage . . . what is 75% of 76 ? 57

Answers:

=========================================================

Explanation:

The ratio 3:2 scales up to 3x:2x for some positive whole number x.

This tells us that the first team has 3x people and the second team has 2x people. We'll subtract 12 from the first team and add 12 to the second team to represent 12 people moving.

The new team counts 3x-12 and 2x+12 represent team 1 and team 2. Those expressions are in the new proportion 5:4.

This means....

(team 1 new count)/(team 2 new count) = 5/4

(3x-12)/(2x+12) = 5/4

4(3x-12) = 5(2x+12)

12x-48 = 10x+60

12x-10x = 60+48

2x = 108

x = 108/2

x = 54

From this, we then can say:

The two subtotals add to 162+108 = 270 players overall.

If we were to subtract 12 from team 1, and add 12 to team 2, then,

The ratio 150:120 then reduces to 5:4 when we divide both parts by the GCF 30. This helps confirm we have the correct answer.

Answer:

Step-by-step explanation:

Each ratio can be expressed using two numbers that have the same sum. The sum in the first given ratio is 3+2 = 5, and in the second ratio, it is 5+4 = 9. The least common multiple of 5 and 9 is 45, so we can express both ratios so they have a sum of 45:

  3 : 2 = 3(9) : 2(9) = 27 : 18

  5 : 4 = 5(4) : 4(5) = 25 : 20

Here, we observe that the second ratio has numbers that look like 2 was moved from the numerator to the denominator. (27 -2 = 25; 18 +2 = 20) The problem statement tells us 12 athletes were moved, so multiplying the first ratio by 12/2 = 6 will tell us the numbers of players on each original team:

  first team = 27×6 = 162 athletes

  second team = 18×6 = 108 athletes

So you can make 6 prime numbers.

Answer:

6

Answer:

Hey mate!

Step-by-step explanation:

Lets take two places _ _

Now first position is filled in 4 ways (can use 2 3 7 9) that implies 4C1

then second position is filled in 3 ways since for first position we used a digit

and the condition is that not to repeat the digits, so it is done in 3C1 ways.

so the answer is 4*3 or (4C1*3C1)=12;

Answer:

The second option.

Step-by-step explanation:

First, the percentages in the "walk" and "ride bike" sections will have to add to 22% as the information says. All of them do except the third option, so that's ruled out.

Next, the rest of the categories have to finish to complete 100%- so they need to add to 78%. Only one of them do, the second with 18% car and 60% bus!

Hope this helps and have a good day!

Answer: The second one

Step-by-step explanation:

Answer:

= [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

First, plug-in y for 1/3 since y = 1/3

[tex]\frac{1}{5} (\frac{1}{3} ) + \frac{4}{15}[/tex]

then multiply first according to the order of operations, then do the addition:

[tex]\frac{1}{5} * \frac{1}{3} =\frac{1}{15}[/tex]

[tex]\frac{1}{15} + \frac{4}{15}[/tex] = [tex]\frac{5}{15}[/tex]

then reduce:

[tex]\frac{5}{15} \to \frac{2}{3}[/tex]
