Solve for x.
10x + 44
8x - 23

Answers

Answer:

Simplifying

10x + 44 = 8X + -23

Reorder the terms:

44 + 10x = 8X + -23

Reorder the terms:

44 + 10x = -23 + 8X

Solving

44 + 10x = -23 + 8X

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-44' to each side of the equation.

44 + -44 + 10x = -23 + -44 + 8X

Combine like terms: 44 + -44 = 0

0 + 10x = -23 + -44 + 8X

10x = -23 + -44 + 8X

Combine like terms: -23 + -44 = -67

10x = -67 + 8X

Divide each side by '10'.

x = -6.7 + 0.8X

Simplifying

x = -6.7 + 0.8XStep-by-step explanation:

5/6 divide by 1/2 in simplest form

Answers

Answer:

1 2/3

Step-by-step explanation:

To divide fractions you do the Keep Change Flip tactic, meaning keep the first fraction change the operation to multiplication and reverse the second fraction.

So with that being said, 5/6*2/1 would be the equation you need to solve. This would give you 10/6 and you have to change that into a mixed number, 1 4/6 and you can reduce that to SIMPLEST FORM by dividing by 2. 4/2=2 and 6/2=3 so in the end you get 1 2/3.

♨Rage♨

Answer:    (2, 9 )

========================================================

Explanation:

Any point is of the form (x,y). The x coordinate is always listed first.

We're given (2, ___) where the y value is missing in the blank.

So we're given x = 2.

Plug this into the given equation to find y

y = 2x+5

y = 2*2+5 ... replace x with 2

y = 4+5

y = 9

Therefore (2, ___) updates to (2, 9 )

(x - 1)^2 + (y + 3)^2 = 13

Step-by-step explanation:

Given(x - 1)^2 + (y + 3)^2 = 13 x + y = -3​Solution

From the second equation we get

x = - y - 3

Substituting x in the first equation

(- y - 3 - 1)^2 + (y + 3)^2 = 13(-y - 4)^2 + (y + 3)^2 = 13(y+4)^2 + (y+3)^2 = 13y^2 + 8y + 16 + y^2 + 6y + 9 = 132y^2 + 14y + 12 = 0y^2 +7y +6 = 0(y+1)(y+6) = 0y = - 1y = - 6

What is 8,187 divided by 24 (not resulting in a decimal number)?

Answers

Answer:

8,187 divided by 24 is 341.125

Step-by-step explanation:

i hope this helps!

Answer:

The answer is 341.125.

But, if you want it without a decimal, you need to round.

You round up if the first number right of the decimal is over 5 or 5, and down if the first number to the right of the decimal is under 5.

Since the first number to the right of the decimal is 1, it is under 5.

So we round down.

So it would be 341.

The answer without a decimal is 341.

A washing machine is filling up with water at a constant rate. The rate is 3/4 of a gallon in 1/5 of a minute. Don calculated the unit rate to be 3/20 of a gallon per minute. what did he do wrong?​

Answers

Answer: you have to see how many gallons fill the container per minute, so take 3/4 and divide it by 1/5, which gives 15/4. So he multiplied the two numbers instead of dividing.

Step-by-step explanation:

Answer:

[tex]\frac{15}{4}[/tex] gallon per minute

Step-by-step explanation:

Given parameters:

Quantity of gallon = [tex]\frac{3}{4}[/tex] gallon

Time taken  = [tex]\frac{1}{5}[/tex] min

Unknown:

The solution is [tex]\frac{3}{20}[/tex] gallon per minute, what did he do wrong = ?

Solution:

To find the rate:

   Rate  = [tex]\frac{Quantity of gallon}{time }[/tex]

 Input the parameters and solve

  Rate  = [tex]\frac{\frac{3}{4} }{\frac{1}{5} }[/tex]   = [tex]\frac{3}{4}[/tex]  ÷ [tex]\frac{1}{5}[/tex]

                       Invert the [tex]\frac{1}{5}[/tex]  to give 5

                  =  [tex]\frac{3}{4}[/tex] x 5

                  = [tex]\frac{15}{4}[/tex] gallon per minute

The student failed to invert the [tex]\frac{1}{5}[/tex] before multiplying with  [tex]\frac{3}{4}[/tex]
