Answer:
190
Step-by-step explanation:
You want the sum of four 2-digit prime numbers that can be formed from the set of digits {1, 2, 3, 4, 5, 6, 7, 9} using each digit only once.
PrimesThere are 18 primes in the range 13-97 that have unique digits. These can be paired by the digits they use:
{23, 59} and {29, 53} . . . . number total = 82
{41, 67} and {47, 61} . . . . . number total = 108
Sets of 4A set of 4 primes with unique digits can be formed by choosing one of the first two pairs together with one of the second two pairs. For example, one possible choice is ...
{23, 59, 47, 61}
However you do this, the sum of the four primes will be ...
82 +108 = 190

FINDING ANGLE MEASURES Find the value of x. Then classify the triangle by its angles.
Answer:
i hope my answer is right for you
In the given triangle, the value of x is 60°.
What are triangles?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.So, the value of 'x':
We easily know that te given triangle is an equilateral triangle.Where all 3 angles are equal.The Sum of triangles is 180°.Now,
60 + 60 + x = 180120 + x = 180x = 180 - 120x = 60°
Therefore, in the given triangle, the value of x is 60°.

Answer:
Y= 5/3x -7
Step-by-step explanation:
To find the slope with the given points you find the distance between the y values and the x values. (Rise/Run = Y/X). Once you find the pattern you can use it until you find the y intercept if you're using graph paper!
Hope this helps! :)
(Side Note: The distance for the y values from -2 and 3 is +5. The distance for the x values is +3 )

Step-by-step explanation:
El lenguaje algebraico utiliza letras, símbolos y números para expresar en forma breve y concisa enunciados en los que se pide realizar operaciones matemáticas. En otras palabras, el lenguaje algebraico utiliza letras en combinación con números y signos, y, además, las trata como números en operaciones y propiedades.
Siendo x, y, z,n tres números cualesquiera:
1. La suma de tres números cualquiera es igual a 20 unidades: x+y+z=20
2. La diferencia de dos números cualquiera es igual a otro número: siendo la diferencia sinónimo de resta o sustracción, este enunciado se expresa como: x-y=z
3. El cociente de dos números es igual a la mitad (un medio) de otro: siendo cociente como sinónimo de dividir, entonces [tex]\frac{x}{y} =\frac{1}{2} z[/tex]
4. El cubo de un número es igual a 9: Elevar un número al cubo implica que el exponente es 3, entonces x³=9
5. El triple de un número es igual a tres quintas partes de otro: El triple de un número se calcula multiplicando el número por 3, entonces [tex]3*x=\frac{3}{5} y[/tex]
6. El producto de tres números es igual a 15: Siendo producto sinónimo de multiplicación, x*y*z= 15
7. La tercera parte de un número más tres unidades es igual al doble del cuadrado de otro: El doble de un número se calcula multiplicando el número por 2. y el cuadrado de un número implica elevar a ese número por 2, entonces: [tex]\frac{x}{3}+3=2*y^{2}[/tex]
8. El cociente de dos números es igual a 3 octavas partes de otro menos 2 unidades: [tex]\frac{x}{y} =\frac{3}{8} *z-2[/tex]
9. El cuadrado de un número menos 3 unidades: [tex]x^{2} -3[/tex]

A young sumo wrestler decided to go on a special diet to gain weight rapidly. WWW represents the wrestler's weight (in kilograms) after ttt months. W=80+5.4tW=80+5.4tW, equals, 80, plus, 5, point, 4, t What was the wrestler's weight before his special diet?
Answer:
80kg
Step-by-step explanation:
Given:
W = 80 + 5.4t
Where,
W = the wrestler's weight (in kilograms
t = number of months
What was the wrestler's weight before his special diet?
W = 80 + 5.4t
When t = 0 (that is before the weight gain)
W = 80 + 5.4t
= 80 + 5.4(0)
= 80kg
When t = 1 ( first month of the weight gain)
W = 80 + 5.4t
= 80 + 5.4(1)
= 80 + 5.4
= 85.4 kg
The wrestler's weight before his special diet is 80kg
ALTERNATIVELY
W = 80 + 5.4t
80 = the fixed weight
5.4 = weight gained per month
t = number of months
Therefore,
The fixed weight which is 80kg is the weight of the wrestler before the special diet.

Answer:
The measures of the angles: m∠1 = 51°, m∠2 = 39°
Step-by-step explanation:
In this type of question, you should substitute the measures of the angle by the given values and solve the equation to find x, then find the measure of each angle.
∵ m∠1 + m∠2 = 90°
∵ m∠1 = 3x°
∵ m∠2 = (x + 22)°
→ Substitute m∠1 by 3x° and m∠2 by (x + 22)° in the equation above
∴ 3x° + (x + 22)° = 90°
→ Add the like terms in the right side
∴ (3x + x) + 22 = 90
∴ 4x + 22 = 90
→ Subtract 22 from both sides
∴ 4x + 22 - 22 = 90 - 22
∴ 4x = 68
→ Divide both sides by 4 to find the value of x
∴ [tex]\frac{4x}{4}=\frac{68}{4}[/tex]
∴ x = 17
→ Now substitute the value of x in each angle to find them
∵ m∠1 = 3x°
∴ m∠1 = 3(17) = 51°
∵ m∠2 = (x + 22)°
∴ m∠2 = (17 + 22) = 39°
The measures of the angles: m∠1 = 51°, m∠2 = 39°

The glee club has $90 to spend on pens and pencils. Each pen costs $0.75 and each pencil costs $0.15. Let x represent the number of pens, and let y represent the number of pencils.
Part A
Select the equation that describes the number of club pens and pencils that the glee club can buy.
A. 0.15x + 0.75y = 90
B. 0.75x + 0.15y = 90
C. 0.90(x + y) = 90
Part B
What is the greatest number of each type of writing tool that the club can buy?
greatest number of pens =
greatest number of pencils =
Answer:
part A; B and Part B; pencils
Step-by-step explanation:
you want to find out how many pens and pencils you cn buy with that 90$ so you want to do
.75y+.15x=90
pens=50
pencils=50
but you want to add .75+.15 which = .90
then you divide 90/.90
and that equals 100
then split it up and each gets 50

3,500. If the shopkeeper made a profit of 5% on selling rice
cooker to Sita, find the cost price, marked price and discount
amount of the rice cooker.
Answer:
Let be cost price =Rs.100
Then mark price =Rs.120
∴ Selling price =90% of 120
=
100
120×90
=Rs.108
Profit = Selling price− Cost price
=Rs.(108−100)=Rs.8
Profit % =
