isosceles triangles means that the two bottom angles and sides are equal
therefore, you can set R and T equal to each other:
(15x-31)=(9x+11)
(get x to one side)
15x=9x+42
6x=42
x=7
now you can plug x back into the equations:
15(7)-31
105-31
74
R and T = 74
all triangles' internal angles = 180
therefore you can add the two angles then subtract them from 180
74+74=148
180-148=32
S should be 32 :)

what are the coordnates of D if E (-2,2)is the midpoint of DF and F has the coordnates of (3,5)
Hi there & welcome to brainly!
Answer:
( -7 , -1 )Step-by-step explanation:
Let the co-ordinates of D be ( x , y )
Let D ( x , y ) be ( x1 , y1 ) and F ( 3 , 5 ) be ( x2 , y2 )
Midpoint of DF = E ( -2 , 2 )
Now, finding the co-ordinates of D :
[tex]\boxed{\sf{ midpoint = (\frac{x1 + x2}{2} , \frac{y1 + y2}{2} ) }}[/tex]
⇒ [tex]\sf{ ( - 2 , 2 ) = (\frac{x + 3}{2} , \frac{y + 5}{2} )}[/tex]
Equating corresponding elements, we get :
[tex]\sf{-2 = \frac{x + 3}{2} }[/tex]
⇒ [tex]\sf{ -4 = x + 3 }[/tex]
⇒ [tex]\sf{ x + 3 = -4 }[/tex]
⇒ [tex]\sf{ x = -4 - 3}[/tex]
⇒ [tex]\sf{x = -7 }[/tex]
Again,
[tex]\sf{ 2 = \frac{y+5}{2} }[/tex]
⇒ [tex]\sf{y + 5 = 4 }[/tex]
⇒ y = 4 - 5
⇒ y = -1
Hence, The co-ordinates of D = ( -7 , -1 )
Hope I helped!

Three times the square of a number is greater than a second number. The square of the second number increased by 6 is greater than the first number. Which system of inequalities represents these criteria?
Given:
Three times the square of a number is greater than a second number.
The square of the second number increased by 6 is greater than the first number.
To find:
The system of inequalities represents these criteria.
Solution:
Let the first number be x and the second number be y.
Three times the square of a number is greater than a second number.
[tex]3\times x^2>y[/tex]
[tex]3x^2>y[/tex] ...(i)
The square of the second number increased by 6 is greater than the first number.
[tex]y^2+6>x[/tex] ...(ii)
Therefore, the system of inequalities represents these criteria has inequalities [tex]3x^2>y[/tex] and [tex]y^2+6>x[/tex], where x is first number and y is second number.
The system of inequalities represents given criteria are [tex]3x^{2} > y[/tex] and [tex]y^{2} +6 > x[/tex].
Let us take the numbers as x and y respectively.
First number = x
Second number = y
What is inequality?
Inequality is the relationship between two expressions that are not equal to one another.
Three times the square of the first number is greater than a second number:
This means, [tex]3x^{2} > y[/tex]
The square of the second number increased by 6 is greater than the first number:
This means, [tex]y^{2} +6 > x[/tex]
Therefore, the system of inequalities represents given criteria are [tex]3x^{2} > y[/tex] and [tex]y^{2} +6 > x[/tex].

Abigail is making a trail mix. She pours 2 15 cups of pretzels, 35 cups of raisins, 1 cup of peanuts, and 45 cups of M&Ms into a bowl. How many total cups of trail mix will she have?
Answer:
296 cupsStep-by-step explanation:
We are expected to solve for the total number of cups, we can achieve this by adding all the individual ingredients together.
Given the number of cups poured
pretzels= 215 cups
raisins= 35 cups
peanuts= 1 cup
M&Ms= 45 cups
So the total is 215+35+1+45= 296 cups

Answer:
X= 128º
Step-by-step explanation:
A triangle is stated to have 180º. This means that since we know 2 sides of the triangle you can simply subtract them from one another.
Doing this you would get: 180 - 90 - 38 = 52º
Noticing that X is on a straight line, this would result in the fact that X is on a line of 180º.
Subtracting the angle we found in the triangle would result you with the answer of:
180 - 52 = 128º for the value of X

A 1×6 square unit rectangular grid has to be covered with six 1×1 square unit tiles. Three of the tiles are yellow, two are white, and one is blue. In how many ways can this task be done if
b
no two neighboring tiles are the same color?
The number of ways the task of Rearranging the rectangular grid can be done if no two neighboring tiles are the same color is;
P(no two neighboring tiles are same) = 60 ways
We are given;
Number of yellow tiles; n_y = 3
Number of white tiles; n_w = 2
Number of blue tiles; n_b = 1
Now, if no two neighboring tiles can be the same tile Color, it means that;
P(no two neighboring tiles are same) = number of ways when no restriction/((n_y)! × (n_w)! × (n_b)!)
>> P(no two neighboring tiles are same) = 6!/(3! × 2! × 1!)
>> P(no two neighboring tiles are same) = 720/12
P(no two neighboring tiles are same) = 60 ways

At its highest point, the elevation of a county is 5,763 feet above sea level. At its lowest point, the elevation of the county is 8 feet below sea level
Answer:
Expression = (y + 5,763) - (y - 8)
Simplified expression = 5,763 + 8
Step-by-step explanation:
• Note: The question is incomplete, however, the concluding part is ; write an expression, using integers to represent the difference between the elevations.
We can make y represent the sea level.
Since the highest point of the country is 5,763 feet above sea level, it Means that the expression can be written as;
y + 5,763
Also, we know that the lowest point is 8 feet below the sea level, hence expression can be written as;
y - 8
We can then find the difference(expression) between both elevation.
= (y + 5,763) - (y - 8)
When the expression is further simplified, we'll have;
5,763 + 8

Answer:
-6
Step-by-step explanation:
-3/2 x 4/1 = 12/2
Simply to -6/1 or -6
The required temperature would be -6°C at 4:00 pm, which is determined by the expression -3/2 × 4/1.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
At midday, the temperature is 0 degrees Celsius. For four hours, the temperature decreases by -3/2 degrees Celsius per hour.
According to the given condition, we can write the expression as:
⇒ -3/2 × 4/1
⇒ -12/2
Apply the division operation to get the solution
⇒ -6
So, the time at which the temperature goes -6°C is 4:00 PM.
Therefore, the required temperature would be -6°C at 4:00 pm.
