Answer:

A

Step-by-step explanation:

Distrubute the 5,...

5 x 7b = 35b

5 x 4c = 20c

5x 3 = 15

35b - 20c + 15

Chow,...!

Answer:

x = 70

Step-by-step explanation:

180 - 140 = 40

2x + 40 = 180

180 - 40 = 140

140 / 2

x = 70

Answer:

Step-by-step explanation:

(1,8) (-1,-2)

Slope: (-2-8)/(-1-1) = -10/-2 = 5

y -8 = 5 (x - 1)

y - 8 = 5x - 5

y = 5x +3

Step-by-step explanation:

x = 4.13636363

100x = 413.636363

100x - x = 413.636363 - 4 .13636363

99x = 409.5

x = 409.5 / 99

Answer:

[tex]\frac{91}{22}[/tex]

Step-by-step explanation:

Given: 4.1363636...  

Let x=4.1363636...

We can see number 36 ( 2 digit repeating ) so we will multiply it by 100

On multiplying both sides by 100

100x=100*4.1363636...

100x=413.63636 .....

We can write it in term of x

100x=x+409.5

On subtracting both sides by x

100-x=409.5

99x = 409 .5

On dividing both sides by 99

x=[tex]\frac{409.5}{99}[/tex]

x=[tex]\frac{4095}{990}[/tex]

x=[tex]\frac{819}{198}[/tex]

On dividing both number by 9

x=[tex]\frac{91}{22}[/tex]

Therefore, x =[tex]\frac{91}{22}[/tex]

Answer:

2 is the common ratio

Step-by-step explanation:

Common ratio is obtained by dividing any term from it's previous term.

1 ÷ 1/2 = 2

2 ÷ 1 = 2

Hence 2 is common ratio.

Answer:

This is the sum --->  4x^2y + 4xy^2 - 1

Step-by-step explanation:

(3x^2y+4xy^2-2y^3+3) + (x^2y+2y^3-4)

(remove the parenthesis)

= 3x^2y + 4xy^2 - 2y^3 + 3 + x^2y + 2y^3 - 4    

(now, group the like terms)

= -2y^3 + 2y^3 + 4xy^2 + 3x^2y + x^2y + 3 - 4  

(add the elements you think are alike or similar)

= -2y^3 + 2y^3 + 4xy^2 + 4x^2y + 3 - 4              

=  4xy^2 + 4x^2y + 3 - 4  

= 4xy^2 + 4x^2y - 1

Answer:

the sum is  4x^2y + 4xy^2 - 1

Answer:

x = 5/33 or 0.151515151

Step-by-step explanation:

7(-6x-2) = 8(3x-4)

step 1: simplify the equation.

-42x - 14 = 24x - 4

step 2: isolate the variable (using the balance method).

-42x - 14 + 14 = 24x - 4 + 14

-42x = 24x + 10

-42x - 24x = 24x - 24x + 10

-66x = 10

step 3: solve for x.

x = 10 ÷ -66

x = 5/33

Answer:

[tex] {ax}^{3} + 4ax \\ [/tex]

factorise out a and x :

[tex] { \boxed{answer{= ax( {x}^{2} + 4) }}}\\ but \: farther \: more : \\ = ax( {x}^{2} + {2}^{2} )[/tex]

but from general factorization:

[tex]{ \boxed{( {a}^{2} + {b}^{2}) = {(a + b)}^{2} - 2ab }}[/tex]

a » x

b » 2

therefore:

[tex] = ax \{ {(x + 2)}^{2} - 2(x)(2) \} \\ \\ = { \boxed{ \boxed{ax( {x + 2)}^{2} - 4x }}}[/tex]

Answer:

100,000 + 200 + 3

Step-by-step explanation:

Answer:

$290

Step-by-step explanation:

Assuming there are only three phones, let x = the third phone's price

We already got the prices of the two phones: $295 and $375.

(295 + 375 + x)/3 = 320

First, multiply both sides by 3 to isolate the expression in the parenthesis.

[(295 + 375 + x)/3 = 320]3

295 + 375 + x = 960

670 + x = 960

Subtract 670 from both sides

670 + x = 960

- 670     - 670

x = 290

how to convert quinary into binary numbers​?

If this means x in base 5 is equal to y in base 2

You just have to divide in base 5 by 2

Let's take an example.

Answer:

[tex]{ \sf{ = 3 \frac{1}{5} }}[/tex]

Answer:

3 1/5    

Step-by-step explanation:

5 goes into 16 , 3 times with a remainder of 1.

so this leaves you with 3 1/5

Alternatively you can divide 16/5 to get 3.2 this gives the fraction 3 2/10 witch can be simplified to 3 1/5

Answer:

B' = {1, 3, 5, 6, 7}

Step-by-step explanation:

U = {1, 2, 3, 4, 5, 6, 7, 8}

B = {2, 4, 8}

So the complement  ( the set of elements in U but not in B) is:

B' = {1, 3, 5,  6, 7}

Answer:

The student took 28 classes

Step-by-step explanation:

What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.

Answer:

x=−4 and y=−4

Step-by-step explanation:

Let's solve your system by substitution.

y=2x+4;y=0.5x−2

Step: Solve y=2x+4for y:

y=2x+4

Step: Substitute 2x+4for y in y=0.5x−2:

y=0.5x−2

2x+4=0.5x−2

2x+4+−0.5x=0.5x−2+−0.5x(Add -0.5x to both sides)

1.5x+4=−2

1.5x+4+−4=−2+−4(Add -4 to both sides)

1.5x=−6

1.5x

1.5

=

−6

1.5

(Divide both sides by 1.5)

x=−4

Step: Substitute−4 fo rx in y=2x+4:

y=2x+4

y=(2)(−4)+4

y=−4(Simplify both sides of the equation)

Answer:

x=−4 and y=−4
