Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Linear equations with two unknowns

Enter an equation or problem

x+4y=0;16y−4x

We think you wrote

x+4y=0;16y-4x

This solution deals with linear equations with two unknowns.

Solution found

{x,y}={0,0}

See steps

Step by Step Solution

System of Linear Equations entered :

 [1]           x+4y=0

 [2]           16y-4x

Equations Simplified or Rearranged :

  [1]    x + 4y = 0

  [2]    -4x + 16y = 0

Graphic Representation of the Equations :

   4y + x = 0        16y - 4x = 0  

Solve by Substitution :

// Solve equation [1] for the variable  x

 [1]    x = -4y

// Plug this in for variable  x  in equation [2]

  [2]    -4•(-4y) + 16y = 0

  [2]    32y = 0

// Solve equation [2] for the variable  y

  [2]    32y = 0

  [2]    y = 0

// By now we know this much :

   x = -4y

   y = 0

// Use the  y  value to solve for  x

   x = -4(-0/32766) = 0

Solution :

{x,y} = {0,0/32766}

Answer:

d) 4.

Step-by-step explanation:

Let Santiago be x years old today.

Then Juan is x + 8 years old.

In 4 years Santiago will be x + 4 years.

In 4 years Juan will be x + 12 years.

From the given information:

x + 4 = 0.5(x + 12)

x = 0.5x + 6 - 4

0.5x = 2

x = 2 / 0.5

x = 4.

Answer:

Step-by-step explanation:

Answer:

  1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

  A = LW +1/2bh

  A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

  LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

The total surface area of the figure is the sum of the two base areas and the lateral area:

  SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².

Answer:

3(16x+9)/4

make sure it's a fraction

Answer:

27 11/4x

Step-by-step explanation:

First we add the similar parts of the expression.

Whole numbers

6 + 9 + 5 + 7 = 27

Then we add the fractions that dont have x.

We only add the numerators (2 and 3) and dont change the denominators (4)

2/4 + 3/4 = 5/4

Now we add the ones with x.

5/4 + 3/4x + 3/4x = 11/4x

Now we combine those parts together, making

27 11/4x

sorry if Im wrong

Answer:

12 1/2 hours

Step-by-step explanation:

0+(1/4)+(1/2)+(3(3/4))+3+(4(5/4))+(3/2)=12.5

Never say anything is too hard because one day this will be second nature solving these fractions

Answer: 12.5 hours watching TV

Step-by-step explanation:

Step 1: We know this is an "in all" question, so we first need to find the fractions to add up.

Each dot on the graph represents 1 of each fraction. For example, the dot above the "1/4" means that 1/4 hours were spent watching TV, and the 3 dots above the 1 means that he watched TV for 1 hour in a row 3 times, so the total number of hours for 1 would be 3x1, or 1+1+1.

So we have:

1/4

1/2

3/4

3/4

3/4

1

1

1

1 1/4

1 1/4

1 1/4

1 1/4

1 1/2

(again, each dot represents 1 of each)

Step : Convert these to decimals so it's easier to add

1/4--> 0.25

1/2--> 0.5

3/4--> 0.75

3/4--> 0.75

3/4--> 0.75

1--> 1

1--> 1

1--> 1

1 1/4--> 1.25

1 1/4--> 1.25

1 1/4--> 1.25

1 1/4--> 1.25

1 1/2--> 1.5

0.25+0.5+0.75+0.75+0.75+1+1+1+1.25+1.25+1.25+1.25+1.5= 12.5 hours in all

Answer:

3 6/8

Step-by-step explanation:

30÷8=3 6/8

8×3=24

30-24=6

Answer:

The mixed that represents 30/8 is --> 3 3/4

Step-by-step explanation:

Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

30/8= 3.75 = 3

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (3) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:

30 - (8 x 3) = 6

Step 3: Our mixed fraction

We've now simplified 30/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

3 6/8

Step 4: Simplifying our fraction

In this case, our fraction (6/8) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 6 and 8 is 2.

We can now divide both the new numerator and the denominator by 2 to simplify this fraction down to its lowest terms.

6/2 = 3

8/2 = 4

When we put that together, we can see that our complete answer is:

3 3/4

Answer:

5

Step-by-step explanation:

For the point to be a solution to the equation, it has to lie on the line 5x -2y= 30 and therefore must satisfy the equation.

5x -2y= 30

When x=8,

5(8) -2y= 30

40 -2y= 30

40 -30= 2y (bring constant to 1 side)

2y= 10 (simplify)

y= 10 ÷2

y=5

Thus the missing value is 5.

Answer:

r = 1

Step-by-step explanation:

The equation is,

→ 6r - 1 + 6r = 11

Now the value of r will be,

→ 6r - 1 + 6r = 11

→ 12r = 11 + 1

→ r = 12/12

→ [ r = 1 ]

Hence, the value of r is 1.

Answer:

The answer is 1 r is equal to 1
