Answer:
10
Step-by-step explanation:
Please use " * " or " · " to indicate multiplication; " x " is a variable, not an operator.
(5 + 3) x 2 - 6 => (5 + 3)·2 - 6
Order of operations rules require that we do first any work inside parentheses. So we have:
(5 + 3)·2 - 6 => (8)·2 - 6
Those same rules dictate that we must multiply before subtracting. So now we obtain:
16 - 6 = 10
For which of the following is x = -5 a solution? Select all that apply.
Answer:
Options 2, 3, 4, 5 are the solutions.
Step-by-step explanation:
Option 1).
x + 10 = -5
x = -10 - 5
x = -15
Therefore, x = -5 is not the solution.
Option 2).
-x² + 50 = 25
-x² = 25 - 50
-x² = -25
x² = 25
x = ±5
Therefore, x = -5 is a solution
Option (3)
|2x| = 10
2x = ± 10
x = ± 5
Therefore, x = -5 is a solution.
Option (4)
x < 0
Since, -5 < 0
Therefore, x = -5 is a solution.
Option (5)
2x < 10
x < 5
Since, -5 < 5
Therefore, x = -5 is a solution.
Options 2, 3, 4, 5 are the solutions.

Which numbers are solutions to the equation 30=x2
? Select all that apply.
x=15
x is equal to 15
x=30−−√
x is equal to square root of 30
x=900
x is equal to 900
x=−15
x is equal to negative 15
x=−30−−√
x is equal to negative square root of 30
x=−900
Answer:
x = +√30
Step-by-step explanation:
Please write 30 = x squared as 30 = x^2.
If x^2 = 30, there are two solutions: x = +√30 and x = -√30.
Several possible answers are given. x=30−−√ is closest to the correct one, but must be written as x = √30. Please ask someone how to find the "√" operator in Brainly. Or, just write "sqrt( )" instead.
what's 1.187939392 to the nearest tenth?
Answer:
1.2
Step-by-step explanation:
For this, everything after 8 doesn't matter.
Because 8 is bigger than 5, we will round the number to the left up.
It is because 8 is the hundreth.

The equation 3x – 2y = 18 is in slope intercept
form.
If the y variable was isolated, it would be in
1
form.
(Use all lowercase letters when writing the answers)
Given:
The equation is:
[tex]3x-2y=18[/tex]
To find:
The slope intercept form of the given equation.
Solution:
Slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
We have,
[tex]3x-2y=18[/tex]
It is not in the slope intercept form.
We need to isolate variable y to get the slope intercept form.
The given equation can be rewritten as:
[tex]-2y=-3x+18[/tex]
[tex]y=\dfrac{-3x+18}{-2}[/tex]
[tex]y=\dfrac{-3x}{-2}+\dfrac{18}{-2}[/tex]
[tex]y=\dfrac{3}{2}x-9[/tex]
Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{3}{2}x-9[/tex].

PLEASE HELP Write a one chunk paragraph explaining the steps to solve for the equation 3(2x+1)=4x+5
Answer:
x = 1
Step-by-step explanation:
First perform the indicated multiplication:
3(2x+1)=4x+5 becomes 6x + 3 = 4x + 5.
Consolidate like terms: 2x = 2
Solve for x: x = 1
Answer:
Step-by-step explanation:
To solve the equation, first you would multiply 3 times 2x and 3 times 1. Then, you would write 6x plus 3 on the right side of the equation. Then, you would subtract 3 from both sides of the equation. You then will have 6x=4x+2. Lastly, you would get an answer of x=1

Answer:
9a^4b^10 ( 4 - 9a^12b^20)
Step-by-step explanation:
The greatest common factor of the two terms is 9a^4b^10
You can now remove the greatest common factor outside the brackets.
Inside the brackets, you place the value obtained by dividing 36a^4b^10- 81a^16b^20 by 9a^4b^10
That is = 4 - 9a^12b^20
Please note that the laws of indices i used for the above division is: n^a divided by n^b = n^(a-b)
Now, the factorised answer for your question = 9a^4b^10 ( 4 - 9a^12b^20)

Consider the points.
(2,5) and (-4,5)
If these points are graphed on a coordinate plane, what is the distance between them?
Answer:
6 units
Step-by-step explanation:
Use the distance formula, [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex].
Plug the x and y values from the given points into the distance formula:
[tex]\sqrt{([-4]-2)^{2}+(5-5)^{2}}[/tex].
Solve the square root:
[tex]\sqrt{36}[/tex] = [tex]\sqrt{6^{2}}[/tex] = [tex]6[/tex]
