Consider the equation.

babunello [35]

Answer:

If you use the addition property of equality, what number would you add to both sides of the equal sign to isolate the variable?

You would subtract 5/7 from both sides of the equation

What is the solution?

x = 26/7 or 3 and 5/7

Step-by-step explanation:

x + 5/7 = 31/7

Subtract 5/7 from both sides of the equation:

x + 5/7 - 5/7 = 31/7 - 5/7

x = 26/7

Solve the following equation and then graphically: 16x + =14x + 10

cestrela7 [59]

Answer:

Step-by-step explanation:

Simplifying

16x + -14 = 14x + -10

Reorder the terms:

-14 + 16x = 14x + -10

Reorder the terms:

-14 + 16x = -10 + 14x

Solving

-14 + 16x = -10 + 14x

Solving for variable 'x'.

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

Add '-14x' to each side of the equation.

-14 + 16x + -14x = -10 + 14x + -14x

Combine like terms: 16x + -14x = 2x

-14 + 2x = -10 + 14x + -14x

Combine like terms: 14x + -14x = 0

-14 + 2x = -10 + 0

-14 + 2x = -10

Add '14' to each side of the equation.

-14 + 14 + 2x = -10 + 14

Combine like terms: -14 + 14 = 0

0 + 2x = -10 + 14

2x = -10 + 14

Combine like terms: -10 + 14 = 4

2x = 4

Divide each side by '2'.

x = 2 Simplifying

16x + -14 = 14x + -10

Reorder the terms:

-14 + 16x = 14x + -10

Reorder the terms:

-14 + 16x = -10 + 14x

Solving

-14 + 16x = -10 + 14x

Solving for variable 'x'.

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

Add '-14x' to each side of the equation.

-14 + 16x + -14x = -10 + 14x + -14x

Combine like terms: 16x + -14x = 2x

-14 + 2x = -10 + 14x + -14x

Combine like terms: 14x + -14x = 0

-14 + 2x = -10 + 0

-14 + 2x = -10

Add '14' to each side of the equation.

-14 + 14 + 2x = -10 + 14

Combine like terms: -14 + 14 = 0

0 + 2x = -10 + 14

2x = -10 + 14

Combine like terms: -10 + 14 = 4

2x = 4

Divide each side by '2'.

x = 2

Simplifying

x = 2

Simplifying

x = 2

How do you compute the volume of a partially filled cylinder on its side by knowing the height of the fluid on a vertical diamet

34kurt

Solution :

Since, we can measure the height of fluid. Let it be h.

So height of cylinder is double the height i.e. 2h because cylinder is partially filled.

Also, we can also measure diameter. Let it be d.

Now, we know, radius is haft the length of diameter.

So, r = d/2.

Volume of cylinder is given by :

$V =\pi \times radius^2 \times height \\\\V =\pi\times (\dfrac{d}{2})^2 \times 2h\\\\V = \dfrac{ \pi d^2 h}{2}$

Hence, this is the required solution.

Write an expression to represent the given statement. Use n for the variable. Three times the absolute value of the sum of a num

Veseljchak [2.6K]

Answer:

3 · |x+6|

Step-by-step explanation:

Write out what you see. "Three times" is 3 · something; "the absolute value of the sum of a number and 6" is |number + 6|. We'll use x for our number. Put it all together and you get 3 · |x+6|
