Answer: 54-x

Explanation:

1. We define the variable which is x or n (whichever you choose)

2. We write the algebraic expression that models the following problem:

the difference of 54 and a number.

3. We end up with our answer: 54-n OR 54-x

(Variable doesn't matter but most people use x when they don't have a named variable)

Hope this helps!!

Solve the equation: x-10 - 2x + 7 = 8 + x - 10 - 3x

Minchanka [31]

Answer: If you're looking for the value of x, it's 1.

Step-by-step explanation:

Add the numbers. x-10-2x+7=8+x-10-3x--->x-3-2x=8+x-10-3x

Combine like terms. x-3-2x=8+x-10-3x ---> -x-3=8+x-10-3x

Subtract the numbers.-x-3=8+x-10-3x---> -x-3=-2+x-3x

Combine like terms. -x-3=-2+-3x---> -x-3=-2-2x

Rearrange terms. -x-3=-2-2x---> -x-3=-2x-2

Hope that helps!

The diameter of Circle $Q$ terminates on the circumference of the circle at $(3,0)$ and $(-4,0)$. Write the equation of th

Dahasolnce [82]

The equation of the given circle in the standard form is given as (x + 0.5)² + y² = 3.5².

In the question, we are given that the diameter of Circle $Q$ terminates on the circumference of the circle at $(3,0)$ and $(-4,0)$.

We are asked to write the equation of the circle in standard form.

The equation of the circle in standard form is given as (x - h)² + (y - k)² = r, where (h, k) is the center of the circle, and r is the radius of the circle.

The center of the circle can be found using the midpoint formula, as the center is the midpoint of the diameter.

Thus, the center is at ( (3 + (-4))/2, (0 + 0)/2 ) = ( -1/2, 0 ).

The length of the diameter can be calculated using the distance formula.

Thus, the length of the diameter of the circle is √((-4 - 3)² + (0 - 0)²) = √((-7)²) = √49 = 7.

The radius is half the length of the diameter.

Thus, the radius, r = 7/2.

Now, we have the center (h, k) = (-1/2, 0), and the radius, r = 7/2.

Thus, the equation of the circle in the standard form, (x - h)² + (y - k)² = r can be shown as:

(x - (-1/2))² + (y - 0)² = (7/2)²,

or, (x + 0.5)² + y² = 3.5².

Thus, the equation of the given circle in the standard form is given as (x + 0.5)² + y² = 3.5².

Which choice is equivalent to the expression below ? 3^7.869

inna [77]

The second one:
3^7 x 3^(86/10) x 3^(9/1000)
That is because when you multiply powers with the same base ( in this case they are all 3), you just leave the base as it is and add the exponents
so it is basically 3^(7 + 86/100 + 9/1000) which is 3^7.869
