Answer:

12 =x

Step-by-step explanation:

We  can use proportions to solve

6           x

---- = -------

10        10+10

Using cross products

6 ( 10+10) = x*10

6*20 = 10x

120 = 10x

Divide by 10

120/10 = x

12 =x

Answer:

x = 12

Step-by-step explanation:

ABC ~ ADE

AB/AD = BC/DE

 10/20 = 6/x

x = 20 x 6 ÷ 10

x = 12

Answer: ($2100+96d) + ($2755+116d)

               = $4855+212d

Step-by-step explanation:

I don't understand. what are W, C, Y, Z ?

all I can do is solving the 4 systems of equations for x and y.

y = -2x - 3

y = 2x - 1

adding the equations

2y = 0 - 4 = -4

y = -2

-2 = 2x - 1

-1 = 2x

x = -1/2

y = x + 4

y = -x + 2

adding the equations

2y = 0 + 6 = 6

y = 3

3 = x + 4

x = -1

y = -2x + 3

y = x + 4

multiply second equation by 2, add the result to first

2y = 2x + 8

3y = 0 + 11 = 11

y = 11/3

11/3 = x + 4 = x + 12/3

x = -1/3

y = 2x - 1

y = -x + 2

multiply second equation by 2, add the result to first

2y = -2x + 4

3y = 0 + 3 = 3

y = 1

1 = -x + 2

-1 = -x

x = 1

Answer:

n = [tex]\frac{1}{3}[/tex] , n = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

6n² - 5n - 7 = - 8 ( add 8 to both sides )

6n² - 5n + 1 = 0 ← in standard form

Consider the product of the factors of the coefficient of the n² term and the constant term which sum to give the coefficient of the n- term

product = 6 × 1 = 6 and sum = - 5

The factors are - 3 and - 2

Use these factors to split the n- term

6n² - 3n - 2n + 1 = 0 ( factor the first/second and third/fourth terms )

3n(2n - 1) - 1(2n - 1) = 0 ← factor out (2n - 1) from each term

(2n - 1)(3n - 1) = 0 ← in factored form

Equate each factor to zero and solve for n

3n - 1 = 0 ⇒ 3n = 1 ⇒ n = [tex]\frac{1}{3}[/tex]

2n - 1 = 0 ⇒ 2n = 1 ⇒ n = [tex]\frac{1}{2}[/tex]

The rate of change of function B is greater than the rate of change of function A

Answer:

.

Step-by-step explanation:

Given that

Money of a man = Rs. X

Money given to his wife = half of the money

= Rs. X/2

Money given to his son = 1/4th of the money

⇛Rs. X/4

Money given to his daughter = Rs. 1200

Total money

⇛ (X/2)+(X/4)+1200 = X

⇛ (2X+X+4800/4 = X

⇛ (3X+4800)/4 = X

⇛ (3X+4800) = 4X

⇛4X=3X+4800

⇛4X-3X = 4800

⇛X = 4800

⇛X-4800 = 0 is the required equation

⇛X = 4800

The money of the man = Rs. 4800 Ans.

Option C

Step-by-step explanation:

Both RUN and NUG have U in the middle of them, so the bottom one would be correct as U is in the center.

Answer:

Marcus has 24 pens while Bryan has 12 pens.

Step-by-step explanation:

Let u rep 1 unit.

Marcus = 2u

Bryan = u

2u+u=36

   3u=36

     u=36÷3

       =12

No. of pens Marcus has

= 2u

= 2×12

= 24

No. of pens Bryan has

= u

= 12

Answer:

1/12

Step-by-step explanation:

1/4 divide by three= 1/4*1/3=1/12

Answer: 1/4 ÷ 3 = 1/12

Explanation: In order to divide fractions, you must follow these 3 simple steps:

Step 1. Turn the second fraction (the one you want to divide by) upside down

(this is now a reciprocal).

Step 2. Multiply the first fraction by that reciprocal.

Step 3. Simplify the fraction (if needed).

Answer:

He had $210.1 after deductions.

Step-by-step explanation:

Add his regular pay and overtime pay together

$375.50 + $65.50 = $441

Now subtract his net pay from the total that he makes before deductions - with his overtime and regular pay.

$441 - $230.90 = $210.1

Answer:

This is the Idenity Property

Step-by-step explanation:

The Identity Property for multiplication states that anything times 1 is the same number.

3x1=3, and 8192x1=8192 (Do you play 2048?)

The zero property: Anything multiplied by zero is zero.

1000000000000000000000000000000x0=0, 4096 x 0 = 0, and so on.

The associative property: Any where numbers are grouped in parenthesis or brackets, you still get the same answer.

(6 x 7) x 78 is the same as 6 x (7 x 78)

The commutative property: When you switch the order of numbers, you get the same answer.

256 x 32 is the same as 32 x 256

Answer:

f = - [tex]\frac{19}{7}[/tex]

Step-by-step explanation:

Given f varies directly with m then the equation relating them is

f = km ← k is the constant of variation

To find k use the condition f = - 19 when m = 14

- 19 = 14k ( divide both sides by 14 )

- [tex]\frac{19}{14}[/tex] = k

f = - [tex]\frac{19}{14}[/tex] m ← equation of variation

When m = 2 , then

f = - [tex]\frac{19}{14}[/tex] × 2 = - [tex]\frac{19}{7}[/tex]
