Answer:
For the first picture, x = 126 and therefore x - 30 = 96
Second picture:
Step-by-step explanation:
since the sum of the angles is 540°, we can say that
x + x + (x - 30) + (x - 30) + (x - 30) = 540
5x - 90 = 540
5x = 630
x = 126
therefore x - 30 = 96°

2nd picture
we use the same method as we did in the first picture:
5x + 2x + 110 = 180
7x + 110 = 180
7x = 70
x = 10, 5x = 50, 2x = 20
Un groupe d'amis décide d'organiser une sortie au restaurant. Ils prennent contact avec un restaurateur qui leur propose une formule à 20 € par convive. Le jour de la sortie, cinq personnes ne peuvent venir. Les participants doivent alors payer 22 € par personne. Combien de personnes étaient initialement prévues ?
Answer:
55
Step-by-step explanation:
Assuming that, initially, there were x people at the time of planning.
As given that, initially, the cost for 1 person = € 20
So, Total cost = € 20x ...(i)
As on the day of the outing, five people cannot come, so the number of people on the outing = x-5.
Now, due to the lesser number of people, i.e (x-5), the cost for 1 person = € 22.
Total cost = € 22(x-5) ...(ii)
As total cost remains the same, so equation the total cost from equations (i) and (ii), we have
[tex]20x= 22(x-5) \\\\\Rightarrow 20x=22x-22\times 5 \\\\\Rightarrow 22x-20x= 110 \\\\\Rightarrow 2x=110 \\\\\Rightarrow x=110/2=55.[/tex]
Hence, at the time of planning, there were 55 people.

Calculate the measure of ∠ PMU and ∠ UPM.
m∠ PMU =
m∠ UPM =
Answer:
The Exterior Angle Theorem states that the measure of the exterior angle of a triangle is
equal to the sum of the measures of the two remote interior angles of the triangle. Angle
PMU is an exterior angle to nPBM and its corresponding remote interior angles are /PBM
and /BPM. So, I can calculate the sum of those two angle measures to find the measure
of /PMU

Harley was eating pizza and had already eaten six pieces before his sister, Samantha, got home. Samantha was worried that she was not going to get a fair share of the pizza and wanted to know how many pieces were in the pizza originally. Harley told her, "I have only eaten 3/8 of the pizza. How many slices where in the pizza when it was whole
Answer:
16 pieces of pizza when the pizza was whole.
Step-by-step explanation:
You know that 6 pieces are equal to 3/8 of the pizza.
Let x represent the total number of pieces and write an equation:
3
-- times x = 6
8
Multiply each side of the equation by 8:
8 times 3
-- x = 8 times 6
8
3x = 48
Divide each side of the equation by 3:
3x 48
--- = ---
3 3
x = 16
Translate the phrase "Multiply by -8, then add 11" into an algebraic expression.

a relation is defined by the points (1,4), (3,-1), (-1,-2) and (1,-3)
this relation (is) (is not) a function because there (is no x-value) (is one x-value) (are two x-values) corresponding to multiple y-values.
Answer:
The answer is that the relation is not a function. because there are two x-values corresponding to multiple y-values
Step-by-step explanation:
Here we want to explain why the given set of points do not represent a function
For a function, we can have same y value for different x value
But, we cannot have same x value for different y value
The sets of point given however has 2 y-values having same x value and as such the points cannot form a function (1,4) and (1,-3)
Line BC is represented by 3x + 2y = 8. Line AD is represented by –3x – 2y = 6. What is the relationship of line BC to line AD? Explain how the sum of the equations demonstrates this relationship.
Answer:
2
Step-by-step explanation:
if you suntract the 2 you, 3x cancels 2y cancels, 8-6 is 2
Answer: Line BC is parallel to line AD. The system of equations has the sum 0 = 14. Since this is a false equation, the system has no solution, which means the lines will never intersect.

Which of the following is not an ordered pair from the function f(x) = -3x + 4?
A. (2,-2)
B. (5, -11)
C. (-3, 13)
D. (-6, 21)
The correct answer is D. (-6, 21), as it is not an ordered pair from the function f(x) = -3x + 4.
To determine which of the ordered pairs is not from the function f(x) = -3x + 4, we need to substitute the x-value of each ordered pair into the function and check if it matches the corresponding y-value.
A. (2, -2)
Substituting x = 2 into the function: f(2) = -3(2) + 4 = -6 + 4 = -2
The y-value (-2) matches the given ordered pair. This is a valid solution.
B. (5, -11)
Substituting x = 5 into the function: f(5) = -3(5) + 4 = -15 + 4 = -11
The y-value (-11) matches the given ordered pair. This is a valid solution.
C. (-3, 13)
Substituting x = -3 into the function: f(-3) = -3(-3) + 4 = 9 + 4 = 13
The y-value (13) matches the given ordered pair. This is a valid solution.
D. (-6, 21)
Substituting x = -6 into the function: f(-6) = -3(-6) + 4 = 18 + 4 = 22
The y-value (21) does not match the given ordered pair (-6, 21). This is not a valid solution.
Therefore, the correct answer is D. (-6, 21), as it is not an ordered pair from the function f(x) = -3x + 4.

What is 35% off 65 Dollars An item that costs $65, when discounted 35 percent, will cost $42.25 The easiest way of calculating discount is, in this case, to multiply the normal price $65 by 35 then divide it by one hundred. So, the discount is equal to $22.75.
6th grade math help me pleaseeee
Answer:
-27
Step-by-step explanation:
what is the value of x in the triangle 50° and 55° in the bottom with x at the top 50 on the left 55 on the right
So, we know that the internal angles of a triangle add up to 180 degrees, yes?
60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.
Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!
Hope I helped!! :)

On the radio one morning, a weather reporter stated that the tempature was two degrees below zero, but the tempature would cotinue to rise throughout the day. Which inequality can be used to represent readings, T, that day? A. T < -2 B. T < -2 ( _ UNDER < ) C. T > - 2 D. T > -2 ( _ UNDER >)
Answer:
T ≥ -2
Step-by-step explanation:
Given
Temperature = 2° below 0°
Required
Represent as an inequality
First, we need to calculate the temperature in the morning.
2° below 0 means.
Temperature = 0° - 2°
Temperature = -2°
Next, we determine the temperature at any time.
The question says the temperature continues to rise during the day.
Represent this with T
This means T will be greater than -2°
However, we need to consider where the temperature started from.
In other words, T = -2
Combine T = -2 and T = -2 together, we have:.
T ≥ -2
Hence, the inequality that represents the scenario is T ≥ -2
