Which Which value of x makes this equation true? -3x+10=5x-8

value of x makes this equation true? -3x+10=5x-8

Answers

Answer:

9/4

Step-by-step explanation:

-3x+10=5x-8

or, -3x-5x = -8-10

or, -8x=-18

or, 8x=18 (i.e. - is cancelled)

or, x=18/8

i.e. x=9/4

Hence, the value of x is 9/4

Answer:

The value of x is 9/4

Step-by-step explanation:

-3x+ 10 = 5x - 8

Add 3x both side

-3x + 3x + 10 = 5x + 3x - 8

10 = 8x - 8

Now, Add 8 both side

10 + 8 = 8x - 8 + 8

18 = 8x

8x = 18

Now, Divide by 8 from both side

8x/8 = 18/8

x = 9/4

Thus, The value of x is 9/4

FOR VERIFICATION ONLY:

-3x + 10 = 5x - 8

-3(9/4) + 10 = 5(9/4) - 8

-27/4 + 10 = 45/4 - 8

-27 + 4 × 10/4 = 45 - 8 × 4/4

-27 + 40/4 = 45 - 32/4

13/4 = 13/4

Hence, L.HS = R.H.S

System of equations is a finite set of equations for which common solutions are sought.

We have,

[tex]4x + 3y = 8[/tex]    

[tex]4x-3y = -16[/tex]

So,

Using the linear combination method,

i.e. adding the given equations,

Answer:

The dimensions of the rectangle are:

2a^2b^2 and 3ab^2 + 5a + 7b

Step-by-step explanation:

The question is asking for the length and width of the rectangle, and gives you an equation that shows the area of the rectangle. It says to factor out the  GCF to find these dimensions. In simpler terms, the question wants you to divide the equation for the area, 6^3b^4 + 14a^2b^3 + 10a^3b^2, into two different equations for the length and width, which can't be divided more.

We have three terms to find the greatest common factor (GCF) of. 6^3b^4, 14a^2b^3, and 10a^3b^2. First, let's factor out the 2. This leaves us with

2(3^3b^4 + 7a^2b^3 + 5a^3b^2)

It seems like we're done with factoring out coefficients, for 3, 5, and 7 are all prime. Now, variables. Each term has a factor of a^2b^2. (not more, for this is the limit of  14a^2b^2.)

2a^2b^2(3ab^2 + 7b + 5a) .   (this is the same as the answer above, but I changed the order of 7b and 5a there because some online things are specific and don't like it if you don't put the equations in order.)

Jared bought 7 cans of paint. A can of red paint costs $3.75. A can of black paint costs $2.75. Jared spent $22.25 in all. How many cans of black (b) and how many cans of red (r) did he buy? r+b=7 3.75r+2.75b=22.25 [?] red [ black Enter​

Answers

Answer:

b = 4

r = 3

Step-by-step explanation:

r + b = 7

solve for 'r' to get r = 7-b

now substitute '7-b' for r in the second equation:

3.75(7-b) + 2.75b = 22.25

26.25 - 3.75b + 2.75b = 22.25

-b = -4

b = 4

r = 3

Jared bought 3 cans of red paint (r = 3) and 4 cans of black paint (b = 4).

To solve this problem, using algebraic equations. Jared recently bought cans of red and black paint, and we want to find out how many cans of each color he purchased. We know that the cost of a red can is $3.75, the cost of a black can is $2.75, and Jared spent a total of $22.25 on the paint. We will set up two equations based on the given information and solve them simultaneously to find the values of "r" (number of red cans) and "b" (number of black cans).

Let's use the following variables:  

r  : Number of red cans purchased  

b : Number of black cans purchased

Now, we can set up two equations based on the information given in the problem:

1. The total number of cans purchased:  

  Since Jared bought 7 cans in total, we can write this as:

   r + b = 7  ... (Equation 1)

2. The total cost of the cans:  

  The cost of each red can is $3.75, so the total cost of all red cans is 3.75r. The cost of each black can is $2.75, so the total cost of all black cans is 2.75b. Jared spent a total of $22.25, so we can write this as:

    3.75r + 2.75b = 22.25  ... (Equation 2)

Now, we have a system of two equations with two variables. We will use the method of substitution or elimination to solve for r and b.

Using substitution, we can rearrange Equation 1 to solve for r:  

r = 7 - b

Now, we can substitute this value of r into Equation 2:

3.75(7 - b) + 2.75b = 22.25

Next, distribute and simplify the equation:

26.25 - 3.75b + 2.75b = 22.25

Combine the b terms:

-1b = 22.25 - 26.25

Simplify further:

-1b = -4

Finally, divide both sides by -1 to find the value of b:

b = 4

Now that we have the value of b, we can find r by substituting the value of b into Equation 1:

r + 4 = 7

Subtract 4 from both sides:

r = 7 - 4

r = 3

Therefore, Jared bought 3 cans of red paint (r = 3) and 4 cans of black paint (b = 4).

What linear equation is represented by the table?

Please hurry!

Best answer gets Brainliest!!!!

A) Y= 2x

B) y= 4x

C) y= 4x -2

D) y= 2x - 2

Answers

Answer:

y = 4x - 2

Step-by-step explanation:

linear equation - y = mx + b

where m = slope and b = y intercept

The y intercept is the y value of the coordinate where x = 0

Looking at the table, we notice that when x = 0, y = -2

Which means that the y  intercept ( b ) = -2

Slope = change in y over change in x

As y goes up 4 x goes up 1

Thus, slope ( m ) =  4

Now we plug in the identified slope and y intercept into " y = mx + b "

we get that the equation is y = 4x - 2

A) Y=2x
