Step-by-step explanation:
[tex]\frac{2}{3} +\frac{1}{6}= \frac{ }{6} \\[/tex]
Here LCM will be 6. (We made the denominator same)
so, now the equation will be :
[tex]\frac{2}{3}+\frac{1}{6} \\\\ =\frac{4}{6} + \frac{1}{6}[/tex]
= 5/6
So, the value in the red box is 5.

Tickets for a play cost $3 for children and $10 for adults. A group of 25 people paid a total of $201 for tickets to the play. How many children were in a group?
Answers
Answer: There were 7 children
Step-by-step explanation:
Let's use x to represent the children and y to represent the adults.
We know they combine to make a group of 25 people so x+y=25
We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201
I will solve by substitution.
Solve for y in the first equation
[tex]x+y=25\\x-x+y=25-x\\y=25-x[/tex]
Sub in our value for y into the other equation and solve for x
[tex]3x+10y=201\\3x+10(25-x)=201[/tex]
Step 1) Simplify
[tex]3x+250-10x=201\\-7x+250=201[/tex]
Step 2) Subtract 250 from both sides
[tex]-7x+250-250=201-250\\-7x=-49[/tex]
Step 3) Divide both sides by -7
[tex]\frac{-7x}{-7} =\frac{-49}{-7}\\x=7[/tex]
Answer:
7 children.
Step-by-step explanation:
Let c = children
Let a = adults
1) We can set up two equations and solve them simultaneously using substitution or elimination method.
c + a = 25
3c + 10a = 201
2) I will use substitution. Make one of the variables the subject; then, substitute it into the other equation.
a = 25 - c
3c + 10(25 - c) = 201
3) Solve for c; then, substitute it into one of the equations.
3c + 250 - 10c = 201
-7c = 201 - 250
-7c = -49
c = -49/-7
c = 7
Let's substitute it into one of the equations.
7 + a = 25
a = 25 - 7
a = 18
Since the question only asked for the number of children, the answer is 7.

The line equation in its slope-intercept form is y = 1.5 · (x - 8), the slope and the y-intercept of linear function are 1.5 (according to the information of the table) and -12, respectively.
How to determine a linear function in slope-intercept form
By analytical geometry we know that linear functions can be constructed by know the location of two distinct points on a Cartesian plane and the slope-intercept form is described below:
y - y₁ = m · (x - x₁) (1)
Where:
x - Independent variabley - Dependent variablex₁, y₁ - Coordinates of the know point.m - SlopeAccording the table, the slope of the function is 1.5, as there a change in y of 3 for a change in x of 2. Lastly, we determine the line equation in slope-intercept form: m = 1.5, x₁ = 8, y₁ = 0
y = 1.5 · (x - 8)
And the y-intercept is found for x = 0:
y = 1.5 · (0 - 8)
y = -12
The line equation in its slope-intercept form is y = 1.5 · (x - 8), the slope and the y-intercept of linear function are 1.5 (according to the information of the table) and -12, respectively. [tex]\blacksquare[/tex]

Remark
There are two ways of calculating % error. Chemistry uses one way. Most others use the second method. I have used the second method.
Measurements
L = 10 in
w = 9 in
h = 4.5 in
Estimated result
350 cubic cm
Solution
Find the volume from the measurements of the Prism
V = L * w * h
V = 10 * 9 * 4.5
V = 405 in^3
Percent Error
% error = 100 * (Calculated Value - Estimated value)/(Estimated Value)
% error = 100 * (405 - 350)/350
% error = 100 * ( 55) / 350
% error = 15.71
% error = 15.7 (rounded)

Find the 2 consecutive integers whose squares have a difference of 239
Answers

Step-by-step explanation:
let the consecutive integers be n and n + 1 , then
(n + 1)² - n² = 239
n² + 2n + 1 - n² = 239
2n + 1 = 239 ( subtract 1 from both sides )
2n = 238 ( divide both sides by 2 )
n = 119
n + 1 = 119 + 1 = 120
the 2 integers are 119 and 120

Find the equation of the line parallel to y = - 1/2x -5, that passes through the point (4, -3). Write your answer in slope intercept form.
Answers
Answer:
y = -1/2x - 1
Step-by-step explanation:
Hi there!
We are given the equation y = -1/2x - 5
We want to write an equation parallel to this line, that passes through the point (4, -3)
Parallel lines have the same slope
In y=-1/2x-5, the equation is written in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
-1/2 is in the place of where m is, therefore it is the slope of the line
It is also the slope of the new line that we want to create.
As we already know the slope of this new line, we can substitute it into our equation (y=mx+b):
y=-1/2x+b
Now we need to solve for b
As the equation passes through the point (4, -3), we can use its values to help solve for b
Substitute 4 as x and -3 as y:
-3 = -1/2(4)+b
Multiply
-3 = -2+b
Add 2 to both sides
-1 = b
Now substitute -1 as b into the equation
y = -1/2x -1
Hope this helps!
