Answer:
Two thirds of 56 is simply two thirds times 56, which can be written as follows:
Two/thirds x 56
Furthermore, you can convert "two" to "2" and "thirds" to "3" and then the equation and answer is:
2/3 x 56 = 37.33
Step-by-step explanation:
The multiplication of the numbers 56 and 2/3 will be 37.33.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
The numbers are given below.
56 and 2/3
Then the multiplication of the numbers 56 and 2/3 will be
⇒ 56 x (2/3)
⇒ 112/3
⇒ 37.33
Thus, the multiplication of the numbers 56 and 2/3 will be 37.33.

Answer:
et's solve your equation step-by-step.
(x+3)2−1=35
Step 1: Simplify both sides of the equation.
x2+6x+8=35
Step 2: Subtract 35 from both sides.
x2+6x+8−35=35−35
x2+6x−27=0
Step 3: Factor left side of equation.
(x−3)(x+9)=0
Step 4: Set factors equal to 0.
x−3=0 or x+9=0
x=3 or x=−9
Answer:
x=3 or x=−9
Answer:
Add 1 to each side
Take the square root of each side
Subtract 3 from each side
Step-by-step explanation:
(x+3)^2 -1 = 35
Add 1 to each side
(x+3)^2 -1+1 = 35+1
(x+3)^2 = 36
Take the square root of each side
sqrt ((x+3)^2) =±sqrt (36)
x+3 = ±6
Subtract 3 from each side
x+3-3 = -3±6
x = -3±6
x = -3+6 x = -3-6
x = 3 x = -9

how would you change x + 3y = 18 -3x - 12y = -75 to eliminate y
Answer: [tex]\bold{y=-\dfrac{1}{3}x+6}[/tex]
[tex]\bold{y=-\dfrac{1}{4}x+\dfrac{25}{4}}[/tex]
Step-by-step explanation:
x + 3y = 18
- x -x
3y = -x + 18
÷3 ÷3 ÷3
y = (-1/3)x + 6
-3x - 12y = -75
+3x +3x
-12y = 3x - 75

Find the value of n 5^10 ÷ 5^8=(1/5)^n
Answer:
5^10 / 5^8 = 5^2 = 25 so the equation becomes 25 = (1/5) ^ n. This means that n = -2.
Answer:
[tex]n=-2[/tex]
Step-by-step explanation:
[tex]\frac{5^{10}}{5^8}=(\frac{1}{5})^n[/tex]
Use the law of exponents.
[tex]5^{10-8}=\left(\frac{1}{5}\right)^n[/tex]
1/5 can be written with a base of 5.
[tex]5^{10-8}=\left(5^{-1}\right)^n[/tex]
Cancel the base 5 on both sides.
[tex]10-8=-1\times \:n[/tex]
[tex]2=-n[/tex]
Multiply both sides with -1.

Alina and Skyla are both solving the equation 2x = 128.
Alina knows the solution to the equation because she knows a power of 2 that equals 128.
Skyla does not know a power of 2 that equals 128, so she graphs two equations, y = 2x and y = 128.
Use the drop-down menus to complete the explanation about how Skyla can use her graph to solve the equation 2x = 128.
Answer:
Skyla looks for the x-value at which the graph of the function [tex]2^x[/tex] intersects the horizontal line defined by the constant function: [tex]f(x)=128[/tex]
Step-by-step explanation:
Look for an answer that involves something like:
By looking for the point where both functions intersect, Skyla can find for which x value the following equation is verified: [tex]2^x=128[/tex]
She must read at which x-value the intersection occurs, and that is the answer.

Answer:
Using the information given, we can use the point-slope form:
y - y1 = m(x - x1)
y - 7 = -1(x + 3)
y - 7 = -x - 3
+7 +7
y = -x + 4, this is slope-intercept form
x + y = 4, this is standard form
What is the slope of the line that passes through the points (-8, -3) and
(-12, -3)? Write your answer in simplest form.
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (- 12, - 3)
m = [tex]\frac{-3+3}{-12+8}[/tex] = [tex]\frac{0}{-4}[/tex] = 0
Slope is rise per run. Rise is difference of y ordinates and run is difference of corresponding x abscissa.
The slope of the line that passes through the given points is 0
Given that:The two specified points are: (-8,-3), and (-12, -3)To find:
Slope of the line that passes through given points.
In graphing, we use Cartesian plane and assume y axis to be perpendicular and mostly we take height or depth related stuffs on y axis, that's why y ordinates will be considered to calculate the rise and x axis is like flat ground, thus x abscissa will be used to calculate the run.
Let the points' coordinates are denoted by symbols as:
[tex](x_1, y_1) = (-8,-3)\\ (x_2, y_2) = (-12, -3)\\ [/tex]
[tex]slope = \dfrac{rise}{run} = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{(-3) - (-3)}{(-12)-(-8)} = \dfrac{0}{-4} = 0[/tex]
Slope is zero means you run whatever, the rise is 0, which means the line is not going to rise and stay flat (horizontal).
