Find the value of x
(21x - 10)
19xº

Answer:

x=4,y=2

Step-by-step explanation:

3x-2y=8 ..........1

2x+y=10...........2

multiply equation 2 by 2 and adding equation 1 and 2 ,we get

3x-2y=8

4x+2y=20

+_________

7x=28

x=28/7=4

:.x=4

again substituting value of x in equation 1 we get

3×4-2y=8

12-8=2y

y=4/2=2

:.y=2

Answer:50

Step-by-step explanation:

Answer:

2(19-c)=2(6c+2)+3c  use distributive property

38-2c=12c+4+3c      combine like terms

38-2c=15c+4        add 2c on both sides

38=17c+4        subtract 4 from both sides

34=17c         divide by 17 on both sides

2=c and you get 2=c or c=2

Step-by-step explanation:

if brainiest is earned its Greatly Appreciated

The solution to the given equation is c =2.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

2(19 - c) = 2(6c + 2) + 3c

Apply the distributive property

38 - 2c = 12c + 4 + 3c      

Combine like terms in the above equation,

38 - 2c = 15c + 4        

Add 2c on both sides of the equation,

38 = 17c + 4        

Subtract 4 from both sides in the above equation,

34 = 17c        

Divide by 17 on both sides

2 = c or

c = 2

Therefore, the solution to the given equation is c =2.

Step-by-step explanation:

-1 - (-12)

the two negative signs before the 12 cancel out so it ends up being

-1+12

-1+12=11

11 and -1 are not equal to each other

Answer:

No

Step-by-step explanation:

-3-(-12)=-3+12

-3+12=9

Answer:

0

Step-by-step explanation:

L Hospital's rule states that as long as u have the form

of infinity / infinity or 0/0 in general you can take its derivative to find the limit.

In this case as X tends to 0, the numerator tends to 0

Denominator will also tends to 0.

We have the 0 / 0 form, which means we can take the derivative for its numerator and denominator which gives

(2x - 2SinxCosx) / 2x | lim x -> 0

= (2x - Sin2x) / 2x | lim x -> 0

Based on this equation, as x tends to 0

both numerator and denominator tends to 0.

So we take its second derivative,

(2 - 2Cos2x) / 2

Now as x -> 0,

we will get (2 - 2)/2 = 0

Answer:

a) $10.4

b) $62.4

Step-by-step explanation:

a) What is the amount of markup? $

$52 - 100%

$X   - 120%

100X = 52*120

100X = 6240

X = 6240/100

X = $62.4

62.4-52=

$10.4  

b) What is the price of the shoes after markup? $

$62.4

Answer:

3375

Step-by-step explanation:

The formula for volume is

volume = length x height x width

or in simpler terms (only works for cubes i think)

v = a^3

so we know that the side is 15cm long, so we substitute that back into the equation, so,

3375 = 15 x 15 x 15

or

3375 = 15^3

I hope that this helps you out :)

Answer:

J = 6/5

Step-by-step explanation:

8−6j=9j−10

Step 1: Simplify both sides of the equation.

8−6j=9j−10

8+−6j=9j+−10

−6j+8=9j−10

Step 2: Subtract 9j from both sides.

−6j+8−9j=9j−10−9j

−15j+8=−10

Step 3: Subtract 8 from both sides.

−15j+8−8=−10−8

−15j=−18

Step 4: Divide both sides by -15.

−[tex]\frac{-15j}{-15}[/tex] = [tex]\frac{-18}{-15}[/tex]

j= [tex]\frac{6}{5}[/tex]

Answer:

j = 1.2

Step-by-step explanation:

8 - 6j = 9j - 10​

We can subtract 8 from each side

8 - 6j = 9j - 10​ - 8

Simplify

-6j = 9j - 18

Subtract 9j from both sides

-6j - 9j = 9j - 18 - 9j

Simplify

-15j = -18

Divide by -15 from both sides

[tex]\frac{-15j}{-15}=\frac{-18}{-15}[/tex]

Solve

j = 1.2

Hope this helps. Have a nice day.

Step-by-step explanation:

Answer:

a

Step-by-step explanation:

solve for y in one equation

2x + y = -4

y = -4 - 2x

plug y into the other equation

5x + 3y = -6

5x + 3(-4 - 2x) = -6

5x -12 -6x = -6

-x - 12 = -6

-x = 6

x = -6

plug x into the equation to find y

y = -4 - 2x

y = -4 - 2(-6)

y = 8

ordered pair: (-6,8)

Answer:300

Step-by-step explanation:

goes up by 75 every two

225+75=300

Answer:

300

Step-by-step explanation:

the value increases by increments of 75

the way i found this out was by doing 150-75 which is 75 and then i did that for the rest of them just to make sure and in order to find the value of n you must add together 225 and 75 to get 300

hope this helps (❁´◡`❁)

and 5 times h

Answer:

Step-by-step explanation:

There are two answers to this making the question slightly ambiguous.

1) 4 - 5*h

2) (4 - 5)*h

It is impossible to tell which answer is the correct one. However, if I had to guess, I would say it is 4-5*h

Answer:

2x^4

Step-by-step explanation:

When multiplying variables with exponents multiply the coefficients (the number before the variable) and add the exponents.

SO to solve you have to find a number that when multiplied by 32 equals 64 and a number when added to 8 gives you 12.

2*32=64

8+4=12

So the answer is 2x^4
