Veremos que el otro lado del triangulo debe medir 20 metros.
¿Cuanto debe medir el otro lado?
Sabemos que para un triangulo rectangulo de catetos P y K, el area es:
A = P*K/2
En este caso, sabemos que el menor de los catetos mide 5 metros, entonces tenemos:
P = 5m
Y tambien sabemos que el area es de 50m^2, reemplazando eso en la ecuación de arriba obtenemos:
50m^2 = 5m*K/2
Ahora podemos resolver esto para K
(50m^2)/5m = K/2
10m = K/2
2*10m = K = 20m
El otro lado debe medir 20 metros.

The school that Brenda goes to is selling tickets to a fall musical. On the first day of the ticket
sales the school sold 4 senior citizen tickets and 6 child tickets for a total of $76. The school
took in $23 on the second day by selling 1 senior citizen ticket and 2 child tickets. What is the
price of one senior citizen ticket and one child ticket?
We can form two equations, let the price of a senior ticket be s and the price of a child ticket be c.
We have from day 1:
A: 3s + 9c = 75
And from day 2:
B: 8s + 5c = 67
Now we can rewrite A as:
A: 24s + 72c = 600
And can rewrite B as:
B: 24s + 15c = 201
Now A-B can be written as:
A-B: 57c = 399
So c = 7
Now substituting this back into A we get:
A: 3s + 63 = 75
A: 3s = 12
So s = 4
We have the price of a senior ticket is $4 and the price of a child ticket is $7 (idk if this is right hope it is!!!)

Find the LCD for 5/m2+9m+20, 3m/m2+11m+28
Answer:
The LCD of the two given fraction is (x + 4)(x + 5)(x + 7)
Step-by-step explanation:
In the algebraic fractions, the LCD is the least common denominator to find it do that:
Factorize each denominatorTake all the factors without repeating factorsLet us do that with our question
∵ The denominator of the first fraction is m² + 9m + 20
→ Factorize it into two factors
∵ 20 = 4 × 5 ⇒ the last term
∵ 4 + 5 = 9 ⇒ the coefficient of the middle term
∴ m² + 9m + 20 = (x + 4)(x = 5)
∴ The factors of m² + 9m + 20 are (x + 4) and (x + 5)
Do the same with the 2nd denominator
∵ The denominator of the second fraction is m² + 11m + 28
→ Factorize it into two factors
∵ 28 = 4 × 7 ⇒ the last term
∵ 4 + 7 = 11 ⇒ the coefficient of the middle term
∴ m² + 11m + 28 = (x + 4)(x + 7)
∴ The factors of m² + 11m + 28 are (x + 4) and (x + 7)
∵ The factors of the two denominators are (x + 4), (x + 5), (x + 4), (x + 7)
→ LCD will be all factors without repeating which means we will
take the factor (x + 4) just one time, we will not repeat it.
∴ LCD = (x + 4)(x + 5)(x + 7)
∴ The LCD of the two given fraction is (x + 4)(x + 5)(x + 7)

The first of three numbers is one-third the value of second number. The second number is 5 less than the third number. If twice the third number is 5 less than the second number, which of the following equations could be used to find the value of the first number, if the first number is represented by x?
Answer: [tex]2(3x+5)=3x-2[/tex] , required equation.
Step-by-step explanation:
As per given we have,
First number = [tex]\dfrac13[/tex] of second number. (i)
Second number = Third number - 5 (ii)
2 (third number)= Second number - 5 (iii)
Put x= first number in (i).
so, [tex]x=\dfrac13[/tex] of second number.
⇒ second number =[tex]3\times x=3x[/tex]
From (ii)
[tex]3x=[/tex] Third number - 5
⇒ Third number =[tex]3x+5[/tex]
From (iii)
[tex]2(3x+5)=3x-2[/tex] , required equation.

Which choice is the equation of the line that passes through the point (5, 19) and has a slope of m =12 and is written in slope-intercept form?
Answer: y = 12x - 41
Step-by-step explanation:
The choices are not given, but you can figure this out.
Slope intercept form is y = mx + b
Substitute the y and x-values into the equation to calculate b, the y-intercept.
19 = 12(5) + b
19 = 60 + b
-60 + 19 =b
-41 = b
Write the equation with y and x, include the given slope and the calculated y-intercept:
y = 12x + 41

Jack has 24 game cards. He divides them between his brother, his sister, and himself in the ratio 2:1:5.
How many cards does each get?
Answer:
brother gets 6 cards
sister gets 3 cards
he gets 15 cards
Step-by-step explanation:
this can be rewritten as
2x + x + 5x = 24
combine like terms
8x = 24
divide both sides by 8
x = 24/8
x = 3
now, multiply x by each part of the ratio.
his brother = 2 * 3 = 6
his sister = 1 * 3 = 3
himself = 5 * 3 = 15

Frederick, Josiah, and Shawnda each had 2 rolls of raffle tickets with 12 tickets in each roll.
Josiah hands out half of his tickets and Shawnda hands out one fourth of her tickets.
How many tickets do they have left altogether?
Answer:
they all have 52 left altogether
Step-by-step explanation:
they all have 2 rolls with 12 so that means they all have 24 if josiah hands out half of his tickets he would have 12 tickets left
If shawnda hands out 1 fourth of her tickets she will have 18 tickets
24 + 12 + 18 =54

Felica is trying to simplify the expression 9 + (8 x 9) - (18\3
Answer:
The answer is 75.
Step-by-step explanation:
First, we apply the rule of PEMDAS (or whatever order of operations rule you have learned). In this equation, we first solve inside the parentheses.
8 x 9 = 72
18/3 = 6
Now, our equation has become 9 + 72 - 6. We can solve this left to right:
9 + 72 = 81
81 - 6 = 75

7. 3n + 6 = 66
8. Let n = Mayah's sister's age
let m = Mayah's age
let b = Mayah's brother's age
m = n - 2
b = n + 4
m + b + n = 26
⇒ n - 2 + n + 4 + n = 26
⇒ 3n + 2 = 26
9. 2n - 5
10. 2b - 6 = 16
11. n + 5 = 12
⇒ n = 7
12. c + 18 = 29
⇒ c = 29 - 18 = 11
13. h = 8 · 5 = 8 × 5 = 40
14. 453 + 364 + n = 1000
⇒ n = 1000 - 453 - 364
⇒ n = 183
15. 3n + 11 = 35
⇒ 3n = 35 - 11
⇒ n = 24 ÷ 3
⇒ n = 8
