Answer:

“A.”

Step-by-step explanation:

15 + 3x is the equation, so we need to have the 3 multiplying by “x” no matter what.

Answer “A.” 3(5+x) would give us 15+3x when the 3 is distributed to the 5 and the “x”

You are welcome :D

Answer:

[A] 3(5+x)

Step-by-step explanation:

To Find which expression is equivalent to 15 + 3x

We can simplify to see:

Start with [A] 3 ( 5 + x )

3 · x = 3x

3 · 5 = 15

3x + 15

True

Next we have [B] 5 ( 3 + x)

5 · x = 5x

5 · 3 = 15

5x + 15

False

Then we have [C] 3 ( 5 + 3x)

3 · 3x = 9x

3 · 5 = 15

9x + 15

False

Finally, we have [D] 5 ( 3 + 3x)

5 · 3x = 15x

5 · 3 = 15

15x + 15

False

3x+15 is the same thing as in 15 + 3x

Thus, [A] 3 ( 5 + x) is the correct answer.

Answer:

a: 89/100

b: 19/100

c: 28/100

Step-by-step explanation:

for a, take every number greater than 10. there are 100 chips, so 89/100 chips are greater than 10. do this for each of the other questions.

The order for the probabilities of the events by placing the event with the greatest probability on top is

1. The label is a number between 30 and 60

2. The label is a number less than 20

3. The label is a number greater than 10

Below are the correct order of the probabilities from greatest to least:

1. The label is a number between 30 and 60

2. The label is a number less than 20

3. The label is a number greater than 10

The reason for this order is that there are 31 chips with labels between 30 and 60, 19 chips with labels less than 20, and 90 chips with labels greater than 10.

Therefore, the correct answer is as given above.

Answer:

A, B, and E.

Step-by-step explanation:

We know that one vertex is at (5, 4), and each side of our square is 3 units long.

Then the distance between the known vertex and another vertex is 3 units (if those vertexes are connected by a side of the square) or (√2)*3  units (if those vertexes are connected by the diagonal of the square).

Also remember that the distance between two points (a, b) and (b, c) is:

distance = √(  (a - c)^2 + (b - d)^2)

So we need to find the distance between our point and all the ones given in the options:

A) the distance between (5, 4) and (5, 1) is:

distance = √( (5 - 5)^2 + (4 - 1)^2) = 3

Then point (5, 1) can be a vertex.

B) The distance between (5, 4) and (5, 7) is:

distance = √( (5 - 5)^2 + (4 - 7)^2) = 3

Then (5, 7) can be a vertex.

C)  The distance between (5, 4) and (7, 8) is:

distance = √( (5 - 7)^2 + (4 - 8)^2) = √( 2^2 + 4^2) = √20

Point (7, 8) can not be a vertex.

D)  The distance between (5, 4) and (2, 6) is:

distance = √( (5 - 2)^2 + (4 - 6)^2) = √( 3^2 + 2^2) = √13

Point (2, 6) can not be a vertex.

E) The distance between (5, 4) and (2, 1) is:

distance = √( (5 - 2)^2 + (4 - 1)^2) = √( 3^2 + 3^2) = √18 = √(2*9) = √2*√9 = √2*3

Then point (2, 1) can be a vertex.

Answer:

first one and  thrid one

Step-by-step explanation:

When you go into this problem, you want to figure out your marble ammount to 50 so in this case we will say C for color and 50 for the total ammount of marbles.

We know 15 are pink, 8 are black, 2 are green, 18 are clear, and 7 are striped

15P/50

8B/50

2G/50

18C/50

7S/50 for a total of 50 marbles

Now we use the chart to decide our awnsers  

A. We know our propability of drawing a green and clear is 20/50 which if we simplify is a 2/5 ratio. If We put this in perspective 2/5 is rare and is unlikley to even.

B. We know a striped marble is 18/50 or 1.8/5 ratio which is mainly unlikely

C. We have 23/50 marbles that are black and pink, our propability is about 2.3/5 and gives us an even chance to get one of these

D. We know we have 33/50 marbles that are pink and clear and gives us a 3.3/5 chance of getting one of  these and gives us an even to likely chance of getting one of these.

E. If we have a total of 17 marbles in these 3 colors, we have a 1.7/5 chance of getting one of these and is probably impossible to unlikey.

Answer:

You would have a horizantal line with a y-intercept of 1.

Step-by-step explanation:

Answer: y is less than or equal to 1

Step-by-step explanation:

Whenever you see parentheses you should automatically think of P.E.M.D.A.S.

Step 1:

In order to get rid of the parentheses you will have to combine like terms, meaning that the 7 will need to be multiplied by whats inside the parentheses.

7 x y = 7y

7 x 2 = 14

Rewritten, your equation should look like this: 7y + 14 - 6 less than or equal to 15

Step 2:

Next, we need to get rid of the 6 which means that 6 should be added in order to cancel it out. 6 should also be added to the other side of the equation.

-6 + 6 = 0

15 + 6 = 21

Rewritten, your equation should look like this: 7y + 14 less than or equal to 21

Step 3:

In order to further balance out the equation, you will need to subtract the 14 from both sides of the equation.

14 - 14 = 0

21 - 14 = 7

Rewritten, your equation should look like this: 7y is less than or equal to 7

Step 4:

Finally, you should divide both sides by seven!

7y/7 = y

7/7 = 1

Rewritten, your equation should look like this: y is less than or equal to 1

Answer:

A triangle is 180 degrees and you have a 30 and 50 angle so the third angle should equal 100. so the answer should be 45 and here's why

Step-by-step explanation:

Subtract 10 from both sides

2x+10=100

2x+10-10=100-10

Simplify

Subtract the numbers

2x=90

Divide both sides by the same factor

2x=90

2x/2 = 90/2

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

x=45

Solution

Answer:

8:6 , 12:9 , 16:12

Step-by-step explanation:

To find equivalent ratios is like finding equivalent fractions :

We simply multiply both numbers of the ratio by the same number.

You can also do the reverse to simplify a ratio.

4:3 × 2 = (4×2):(3×2) = 8:6

4:3 × 3 = (4×3):(3×3) = 12:9

4:3 × 4 = (4×4):(3×4) = 16:12

Therefore 3 ratios that are equivalent to 4:3 are :

8:6 , 12:9 , 16:12

The distance that Gordon would bike is 15 miles.

The first step is to determine the average speed of the mountain bike. Average speed is how fast an object moves with respect to time.

Average speed = total distance / time

3/4 ÷ 1/10

3/4 x 10 = [tex]\frac{30}{4}[/tex] = 7[tex]\frac{1}{2}[/tex]

The formula to determine the distance he would cover given his speed is

Distance = average speed x time

7[tex]\frac{1}{2}[/tex] x 2

[tex]\frac{15}{2}[/tex] x 2 = 15 miles
