Required

Solve

Two-thirds means [tex]\frac{2}{3}[/tex]

Mathematically, Two-thirds times 12.33  implies

[tex]\frac{2}{3} * 12.33[/tex]

Solving further

[tex]\frac{2 * 12.33}{3}[/tex]

[tex]\frac{24.66}{3}[/tex]

[tex]8.22[/tex]

Hence:

[tex]\frac{2}{3} * 12.33=8.22[/tex]

Step-by-step explanation:

Answer:

x=3

y=8

Step-by-step explanation:

the given equations are y=3x-1 --------(1)

and y=2x+2---------(2)

Using substitution method,

and solving y=3x-1

y+1=3x

or y+1/3 =x ------(3)

Putting the value of x= y + 1 / 3 in equation 2

y= 2x+2

or, y = 2 ( y + 1/3) +2

or, y= 2y + 2 / 3 +2

or, y = 2y + 2 + 6 // 3 ( Taking LCM)

Or, 3 y = 2y + 2 + 6 ( the denominator gets multiplied to y)

OR, 3 Y - 2Y =6 PLUS 2

or y = 8

therefore, y=8

now substituting the value of y=8 in equation (3)

y + 1 /3 = x

or ,,, 8 plus 1 by 3 =x

or,,,,, 9 by 3 =x

Therefore, x is 3

Answer:

1, -2

Step-by-step explanation:

The x axis is 1 to the right, and the y axis is 2 down.

1. 7.2 x 100 =  720

2. 468.8 ÷ 100 =  4.688

3. 0.12 x 1,000 =  120

4. 86.4 ÷ 100 =  0.864

5. 2.001 x 10 =  20.01

6. 1,200 ÷ 1,000 =  1.2

7. 3.41 x 100 =  341

8. 3.41 ÷ 10 =  0.341

9. 0.0031 x 100 =  0.31

10. 5.7 ÷ 100 =  0.057

11. 1.34 x 1,000 =  1340

12. 10 x 0.57 =  5.7

13. 57 ÷ 100 =  0.57

14. 1.068 x 100 =  106.8

15. 168.1 ÷ 10 =  16.81

16. 0.0341 x 100 = 3.41

Answer:

64 child tickets

Step-by-step explanation:

Let's set this up a system of equations. Number child tickets is c and adults are a.

5.1c+8.8a=1144.8

c+a=157

We can now solve by elimination. Let's multiply the second equation by -8.8 so that we are left with the child tickets.

-8.8c-8.8a= -1,381.6

We combine the two equations.

-3.7c=-236.8

Divide both sides by -3.7

c=64

Answer:

85.1 g

Step-by-step explanation:

Boris has 91.5 g of pepper

He used 0.4g to make one plate of scrambled egg

If she made 16 plates of scrambled egg then the amount of pepper that will be left can be calculated as follows

= 0.4×16

= 6.4g

= 91.5g - 6.4g

= 85.1g

Hence Boris will have 85.1g of pepper left

Answer:

Step-by-step explanation:

It expresses that one value will be lesser than the other.

The term 'less than' symbolically represented as '<'.

We can implement certain operations like comparing values, heights, and numbers.

For example, there are 3 pencils in one bag A, and 8 pencils in bag B.

When we compare the two, we can easily observe that bag A has fewer pencils than bag B.

Thus,

Pencils in Bag A       <         Pencils in Bag A

           3                     <                    8

Număr în parc = 106

Numărul din parc reprezintă 1/3 din numărul elevilor care participă la activitatea de curățenie.

Pentru a obține numărul total de studenți care participă la activitate; fie numărul total = x

Prin urmare;

1/3 din x = 106

x / 3 = 106

Solution  of the given equation 2x+8=4x-10 is x=9.

Solution of an equation are the values to the unknown variables that makes the equality in the equation true

Given equation is :

2x+8=4x-10,   consider it as equation (1)

To solve this equation firstly, we isolate the terms which contain x in the LHS and the constant terms in RHS.

Then, the equation will become:

2x-4x = -10-8

Solving the LHS and RHS:

-2x = -18

Divide both the sides by -2, we get:

x = -18/(-2)

x = 9

That means x=9 satisfies the given equation.

Hence, x=9 is the solution of the given equation.

Answer:

15ft

Step-by-step explanation:

Calculation for how tall is the tree

First step Let the proportion be x/10ft = 6ft /4ft

Second step is to cross-multiply by 4x

4x =10ft*6ft

4x = 60

Third step is to divide both sides by 4

4x = 60

4x/4=60/4

x=15 ft

Therefore the tree will be 15ft tall

Answer:

The first 5 terms of the sequence are 2, 4, 8, 16 and 32.

Step-by-step explanation:

Given:

[tex]a_{1}[/tex] = 2

[tex]a_{n}[/tex] = 2[tex]a_{n-1}[/tex]   -----------------(i)

To get the first 5 terms of the sequence, substitute in turn, n = 1, 2, 3, 4, 5 into equation (i).

The first term (when n = 1) has been given as:

[tex]a_{1}[/tex] = 2

The second term (when n = 2) is given as:

[tex]a_{2}[/tex] = 2[tex]a_{2-1}[/tex]

[tex]a_{2}[/tex] = 2[tex]a_{1}[/tex]    (but [tex]a_{1}[/tex] = 2 )

=> [tex]a_{2}[/tex] = 2(2)

=> [tex]a_{2}[/tex] = 4

The third term (when n = 3) is given as:

[tex]a_{3}[/tex] = 2[tex]a_{3-1}[/tex]

[tex]a_{3}[/tex] = 2[tex]a_{2}[/tex]    (but [tex]a_{2}[/tex] = 4 )

=> [tex]a_{3}[/tex] = 2(4)

=> [tex]a_{3}[/tex] = 8

The fourth term (when n = 4) is given as:

[tex]a_{4}[/tex] = 2[tex]a_{4-1}[/tex]

[tex]a_{4}[/tex] = 2[tex]a_{3}[/tex]   (but [tex]a_{3}[/tex] = 8 )

=> [tex]a_{4}[/tex] = 2(8)

=> [tex]a_{4}[/tex] = 16

The fifth term (when n = 5) is given as:

[tex]a_{5}[/tex] = 2[tex]a_{5-1}[/tex]

[tex]a_{5}[/tex] = 2[tex]a_{4}[/tex]   (but [tex]a_{4}[/tex] = 16 )

=> [tex]a_{5}[/tex] = 2(16)

=> [tex]a_{5}[/tex] = 32

Therefore, the first 5 terms of the sequence are 2, 4, 8, 16 and 32.

Answer:

Personal observation.

Step-by-step explanation:

Worthy of note is to say that, it's is practically impossible to have a line of different people retell what they heard, saw or experienced in the same way. Because of the fact that human being differs, there's always a difference in the retelling of the story eventually. Everyone seems to retell the story in a manner they can relate to, in a manner of what they understand, and that's given rise to unreliability in personal observation. Not that they're wrong, nor that one is right than the other, but that they're just not reliable.

Answer:

6.25 or 6 1/4

Step-by-step explanation:

Jodie sold 6.25 candy altogether.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that perform the arithmetic operations are called arithmetic operators.

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

For example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

Given that

Jodie sells 2½ pounds of gumdrops,

3 pounds of orange slices, and ¾ pounds of gummi bears.

Convert the fractions into decimals

Number of pounds of gumdrops = 2½ = 5/2 = 2.5

Number of pounds of gummi bears = ¾ = 0.75

So the total amount of candy Jodie sold :

⇒ 2.5 + 3 + 0.75

⇒ 6.25

Hence, Jodie sold 6.25 candy altogether.

Answer:

$16.32

Step-by-step explanation:

First you need to find how much each thing is going to cost.

So for 32 glue sticks, it will cost $44.80 because you multiply 32 by 1.40.

Next you need to find the cost of thebox of crayons, which is $18.88 because you multiply 32 by 0.59.

Then you add those two totals together and you get 63.68.

Lastly you subtract that from 80 to see how much money Ms. Blankenship has  leftover which is $16.32.

The expression in the form of a + ib is

-88 + 8i

where a = -88 and b = 8.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

2(-36 - 3i) + (5 + 2i)(12 - 2i)

Remove the parenthesis.

-72 - 6i + 60 - 10i + 24i + 4

Add like terms.

-88 + 8i

This is in the form of (a + ib).

Where a = -88 and b = 8

Thus,

-88 + 8i is our final expression.
