Answer:

2/18, or 1/9

Step-by-step explanation:

Lets start by finding out how many red, glass marbles there are.

Half of the red marbles of glass, and there are four red marbles. All we need to do is divide 4 by 2.

4/2=2

There are two glass marbles.

Now we just need to add the number of red marbles to yellow marbles. That would be 14+4, which is 18.

In conclusion, there are 2 red marbles, and 18 marbles in total, so it would be 2/18. Simplified, it would be 1/9.

Answer:

6.3 cm

Step-by-step explanation:

The distance from each centimeter is divided into 10 parts.  Point A starts at 0 and goes until right before 6.5.  The big line between each whole number signifies that you are halfway through the centimeter.  As you can see, point B is right before a big line, so can't be bigger than 6.5 nor equal.  The only option that fits this is 6.3 cm

The answer is 6.3 cm

Answer:

721.

Step-by-step explanation:

The total number must be a multiple of 7

One less than the number is the LCM of 2 3 4 5 6 and 8.

The LCM is worked out as follows

2

3

4 = 2*2

5

6 = 2*3

8 = 2*2*2

LCM = 2*2*2* 3*5 = 120

But 121 is not divisible by 7 so it must be a multiple of 120 + 1 which is divisible by 7.

240 + 1 = 241 - not divisible by 7

480 + 1  = 481 - not divisible by 7

720 + 1 = 721

721/7 = 103

Answer:

Step-by-step explanation:

Let say n the number of pennies in the jar.

n is a multiple of 7 : n=7*k

n-1 is a multiple of 2,3,4,5,6,8 so a multiple of the lcm= 120

n-1=120*t

n-1=120*t

n=7*k

120*t=7k-1

7k=120*t+1

[tex]k=\dfrac{120*t+1}{7}\\k=17*t+\dfrac{t+1}{7}\\t=6+7*a\\k=17*(6+7a)+\frac{6+7*a+1}{7} =102+119*a+1+a=103+120*a\\n=7*k=7*(103+120*a)=721+840a\\\\[/tex]

The least number of pennies is 721 (when a=0)

Proof:

n-1=720

720/2=360

720/3=240

720/4=180

720/5=144

720/8=90

721/7=103

Answer:

i finished on the other question yw

Step-by-step explanation:

also not sure if you wanted the values for n

edit:

7. n/2 = 16

8. 2n + 4 = 52

9. 2(n + 5) = 17

10. 3n - 12 = 5

Answer:

7. 32

8. 24

9. 3.5

10. 5.6

Step-by-step explanation:

7. write the equation: n/2=16. Cross multiply.

8. write the equation: 52= 4+2n. Move 4 to the other side and subtract from 52: 48= 2n. Divide both sides by 2.

9. write the equation: 2(5+n)=17. Use the distributive property. Move 10 to the other side and subtract from 17: 2n=7. Divide both sides by 2.

10. write the equation 3n-12=5. move -12 over and add to 5: 3n=17. Divide both sides by 3.

Answer:

Step-by-step explanation:

Important fact: much as I hate to admit it, in all professional sports, there is no team that has made as many appearances in the sports final as the Canadiens.

The ratio you want is 10/32 = 5/16.

The ratio means that for every 5 appearances the rangers made, the Canadiens made 16 appearances.

Answer: 1/2 < 0.65 < 2/3 < 6.5

Step-by-step explanation:

Given information

0.65, 6.5, 2/3, 1/2

Convert fractions into decimals

0.65 = 0.65

6.5 = 6.5

2/3 = 0.67 (Rounded to hundredth place)

1/2 = 0.5

Arrange decimals from least to greatest

0.5 < 0.65 < 0.67 < 6.5

Convert terms back to the given form

1/2 < 0.65 < 2/3 < 6.5

Answer:

70

Step-by-step explanation:

if the train is traveling 90 miles in 2 hours then its going 45 mph so 25 + 45 = 70 and 70 mph is 140 in 2 so then the equation is true

Answer:

equal to

Step-by-step:

Again, the mean reflects the slanted the most.

To summarize, generally if the distribution of data is slanted to the left, the mean is less than the median, which is often less than the mode. If the distribution of data is slanted to the right, the mode is often less than the median, which is less than the mean.

Answer:

Equal

Step-by-step explanation:

The median is the midmoint of all points (as many values below as above this value). The mean is the (sum of values) / (count of values). Since every value has the exact same count, the mean and median will be the same.

Step-by-step explanation:

: 2(2x-7)+2(4x+3)=112

Step-by-step explanation:

Answer: Third Choice. 112 = 2 (2x - 7) + 2 (4x + 3)

Concept:

Here, we need to know how to find the perimeter of a rectangle.

Perimeter (rectangle) = 2l + 2w

l = length

w = width

Solve:

Given information

l = 2x - 7

w = 4x + 3

Perimeter = 112 cm

Given expression

Perimeter = 2l + 2w

Substitute values into the expression

[tex]\boxed{112 = 2 (2x - 7) + 2 (4x + 3)}[/tex]

Expand parentheses

112 = 4x - 14 + 8x + 6

Combine like terms

112 = (4x + 8x) + (6 - 14)

112 = 12x - 8

Add 8 on both sides

112 + 8 - 12x - 8 + 8

120 = 12x

Divide 12 on both sides

120 / 12 = 12x / 12

[tex]\boxed{x=10}[/tex]

Answer:

v = 0

Step-by-step explanation:

-2 (1 - 5v) = - (2 - 4v)

Simplify the equation down to the following:

-2 + 10v = -2 + 4v

Do the inverse operation for each side:

10v = 0 + 4v

6v = 0

6v/0 = 0/0

Answer:

30

Step-by-step explanation:

just divide 60 by 2

If the distance between Nikki's cousin and Nikki is 60 miles and covered in 2 hours then the speed of the train is 30 miles per hour.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distance}{Time}[/tex]

Nikki's cousin lives 60 miles away, so Nikki decided to take the train to visit him. If the trip took 2 hours. Then the speed of the train will be

[tex]\rm Speed = \dfrac{60}{2}\\\\Speed = 30 \ miles/hour[/tex]

Answer:

x = -15

Step-by-step explanation:

Subtract x on both sides

x + 5 = -10

Subtract 5 on both sides

x = -15

Check work:
