Answer:

gcf = 13

13(1+5)

Step-by-step explanation:

GCF = 13, 13*5=65

= 13 + 13(5)

= 13(1+5)

Step-by-step explanation:

probability that the snow will fall on 60%.

What is probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.

Each day has a 60% chance of snow.

each labeled with a different number from 1 to 20.

She picks a card, then returns it to the deck, 4 times.

If 8 appears, it represents a snowy day.

Solving Inequalities (Will mark as brainliest)

1. -15 ≥ x - 7

2. 6y < -48

3. -2y - 4 > 18

4. 2n + (-8) > 12

5. 2n - 6 ≤ -10

6. -5n + 15 ≥ -60

7. -1 + 5n ≤ -26

Answers

Answer:

1. x ≤ -8

2. y < -8

3. y < -11

4. n > 10

5. n ≤ -2

6. n ≤ 15

7. n ≤ -5

Step-by-step explanation:

Your goal is to get just the variable on one side of the inequality!

For example, take -2y - 4 > 18.

Add 4 to both sides. So... -2y - 4 + (4) > 18 + (4)

Now you get -2y > 22. Since y isn't by itself, let's divide both sides by -2.

So, (-2y / -2) > (22 / -2)

Anytime you're dividing something by a negative, remember to FLIP THE SIGNS. So instead of a greater than, it will now be a less than sign <.

Now you get, y < -11

All of the following are equivalent to 2(2a + b) + 8, except _____.
A. 4 a + 2 b + 8
B. 4( a + b + 2)
C. 4 a + 2( b + 4)

Answers

Answer:

B. 4( a + b + 2)

Step-by-step explanation:

Task: Simplify 2(2a + b) + 8

1. Distribute the 2

4a + 2b + 8

---------------------

Evidently, that is the same as A, so A is correct.

Now if we try C, 4a + 2(b+4), we see we need to simplify to check.

So let us distibute the 2.

4a + 2b + 8. Also correct.

This probably means that B is incorrect.

4(a + b + 2)

Let's distribute the 4.

4a + 4b + 8

This is incorrect because only have two "b".

One half because half of his text are to her

Answer:

The answer is

→ 48 text messages

Step-by-step explanation:

Were being asked how many text messages are to Bianca. Today, were using 3 ways on how to solve this problem. 2 are incorrect and 1 is correct.

First, let's use addition.

[tex]120+\frac{4}{5} +\frac{1}{2} =121.3[/tex]

Were not looking for 121.3, it's too high. Therefore, using addition is incorrect.

Second, let's use subtraction..

[tex]120-\frac{4}{5} -\frac{1}{2} =118.7[/tex]

Were not looking for 118.7 either. Therefore, using subtraction is incorrect as well.

Third, let's use multiplication...

[tex]120 * \frac{4}{5} * \frac{1}{2} = 48[/tex]

As a result we got 48. Which is the answer your looking for.

Step-by-step explanation:

The difference in years:

= 2015 - 2004

= 11 years

Josh went to the store and bought chicken that was on sale, he could buy 8 pounds for $15.92 or 5 pounds for $9.95.

Answers

Answer: They are both 1.99 a pound.

Step-by-step explanation:

So we need to find the price per pound to compare the two choices. You take the price then divide it by the number of pounds. 15.92/8=1.99. So $1.99 a pound and then the same for 9.95/5 which is also equal to 1.99. Both come out to be 1.99 per pound so there is no better buy. Cost would be same.

The answer is 1.099.

7.5 x 1.099 = 8.2425 - which is greater than 7.5

All the other options will give you less than 7.5

I hope this helps and please mark me as Brainliest! Thanks!

Answer:

1.099

Step-by-step explanation:

This will make 7.5 x 1.009 higher than just 7.5 because 1.099 is higher than 1. And anything times 1 equals itself, so that means that if you times it by something higher than that, then the main number will go higher. If we do 0.951, then that won't work out because that will decrease the value of 7.5 since it is lower than 1. And if we do just 1, that will keep 7.5 to itself. So, the only option left is 1.099, and this option IS the right one.
