What does it mean to solve an equation?An equation represents equality of two or more mathematical expression.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

If you split the clock, which is a 360 degree circle into 10- minute intervals, what is the central angle of each interval?
Answers
Answer:
Since 15 mins are 90 degrees
10 mins are 60 degrees
Can you show me the steps that you took to get the answer for this question?
Answers
If measure of 1 + measure of 2 = 90
And measure of 1 = x
And measure of 2 = x - 4
You would have the equation of
X + X - 4 = 90
So then you combine like terms
2x - 4 = 90
Then you add 4 on both sides
2x - 4 = 90
+ 4 + 4
2x = 94
Then you divide by 2 to get x alone
And x = 47

An equation is shown below:
4x + 2(x − 3) = 4x + 2x − 11
Part A: Solve the equation and write the number of solutions. Show all the steps. (6 points)
Part B: Name one property you used to solve this equation. (4 points)
Answers
Answer:
Part A: No Solution
Part B: Distributive Property
Step-by-step explanation:
4x + 2x - 6 = 6x - 11
6x - 6 = 6x - 11
-6 ≠ -11
No Solution
Answer:
Part A. Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Part B. Distributive Property
Step-by-step explanation:
Simplifying
4x + 2(x + -3) = 4x + 2x + -11
Reorder the terms:
4x + 2(-3 + x) = 4x + 2x + -11
4x + (-3 * 2 + x * 2) = 4x + 2x + -11
4x + (-6 + 2x) = 4x + 2x + -11
Reorder the terms:
-6 + 4x + 2x = 4x + 2x + -11
Combine like terms: 4x + 2x = 6x
-6 + 6x = 4x + 2x + -11
Reorder the terms:
-6 + 6x = -11 + 4x + 2x
Combine like terms: 4x + 2x = 6x
-6 + 6x = -11 + 6x
Add '-6x' to each side of the equation.
-6 + 6x + -6x = -11 + 6x + -6x
Combine like terms: 6x + -6x = 0
-6 + 0 = -11 + 6x + -6x
-6 = -11 + 6x + -6x
Combine like terms: 6x + -6x = 0
-6 = -11 + 0
-6 = -11
Solving
-6 = -11
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.

5. Cuando abrió sus puertas, una tienda de café ofrecía 6 tipos diferentes de
bocadillos. Desde entonces, agregó dos nuevos bocadillos cada semana.
Si la tienda ofrece ahora 28 bocadillos diferentes, ¿cuántas semanas (s) han
transcurrido desde su inauguración?
?
Answers
Answer:
11 weeks have passed.
Step-by-step explanation:
We can create a linear function that represents the number of bocadillos offered as a function of the number of weeks (s) that went by since the beginning (when the number of bocadillos was 6):
f(s) = 6 + 2 * s
Since now the number of bocadillos is 28, we can solve for s in the equation
28 = 6 + 2 * s
subtract 6 from both sides
28 - 6 = 2 * s
22 = 2 * s
divide both sides by 2
11 = s
Therefore, 11 weeks have passed.

Alright, sorry for possibly wasting the answer, but its either D or B. i think its D, because its a bisector of the line segment, but B reads that it IS perpendicular, but on points not the line. You can rule out which one of the two it is, i would suggest asking a teacher for help or waiting for a better and more reliable answer.
