Find the value of the variable that results in congruent triangles for numbers 6 and 8.
Answer:
x = 28
Step-by-step explanation:
From the figure attached,
AC ≅ FH [Given]
BC ≅ GH [Given]
AB ≅ FG [Given]
ΔABC ≅ ΔFGH [By SSS property of congruence]
Since, m∠A + m∠B + m∠C = 180°
50° + 69° + m∠C = 180°
119° + m∠C = 180°
m∠C = 180° - 119°
m∠C = 61°
m∠C = m∠H [Since, ΔABC ≅ ΔFGH]
(2x + 5)° = 61°
2x = 61 - 5
2x = 56
x = 28
Una escuela compró varios ejemplares del libro A, que cuesta $200.00, y del libro B, que cuesta $150.00. Compró en total 120 libros y pagó $20,500.00 por ellos. ¿Cuántos ejemplares de cada libro compró
Responder:
Copias del libro A = 50
Copias del libro B = 70
Explicación paso a paso:
Costo por libros A = 200
Costo por libro B = 150
Sea el número de libros A = x
Número de libros B = y
Número total de libros comprados = 120
Costo total = 20,500
x + y = 120 - - - (1)
200x + 150y = 20500 - - - (2)
De 1)
x = 120 - y
Sustituya x = 120-y en (2)
200 (120 - años) + 150y = 20500
24000 - 200y + 150y = 20500
24000 - 50y = 20500
-50 años = 20500 - 24000
-50y = - 3500
y = 70
x = 120 - y
x = 120 - 70
x = 50

Sven has $1 and a dime in his pile Dayna has 11 dimes in her pile if Sven gives Dayna $1 and Dayna gives Sven ten dimes will the two piles still be equal in value?
Answer:
The two piles will still be equal in value
Step-by-step explanation:
From the question,
Sven has $1 and a dime in his pile, and
Dayna has 11 dimes in her pile.
Now,
If Sven gives Dayna $1 and Dayna gives Sven ten dimes,
To determine if the two piles will still be equal in value,
First, we will determine what each of Sven and Dayna has presently.
For Sven,
He has $1 and a dime, he gives out $1 and received ten dimes, that means
$1 + 1 dime - 1$ + 10 dimes = 11 dimes
Now, Sven has 11 dimes with him
For Dayna,
She has 11 dimes, she gave out 10 dimes and received 1$, that means
11 dimes - 10 dimes + $1 = $1 and a dime
Now, Dayna has $1 and a dime.
To determine if the two piles will still be equal, we will convert Dayna's dollar ($) to dimes
(NOTE: 10 dimes make a dollar, that is, 10 dimes = $1)
Dayna has $1 and a dime,
$1 + 1 dime = 10 dimes + 1 dime = 11 dimes
∴ She has 11 dimes.
Since, Sven has 11 dimes as well,
Hence, the two piles will still be equal in value.

Frankie solved the math problem below. Find the error in Frankie's work and explain it in words, using math language. 2 1/3 - 1 2/5 2 1/3 x 5/5 = 2 5/15 -1 2/5 x 3/3 = -1 6/15 = -1 1/15
Given:
The expression is
[tex]2\dfrac{1}{3}-1\dfrac{2}{5}[/tex]
To find:
The error in Frankie's work.
Solution:
We need to simplify [tex]2\dfrac{1}{3}-1\dfrac{2}{5}[/tex], so
[tex]2\dfrac{1}{3}=2\dfrac{1}{3}\times \dfrac{5}{5}[/tex]
[tex]2\dfrac{1}{3}=2\dfrac{5}{15}[/tex]
and,
[tex]1\dfrac{2}{5}=-1\dfrac{2}{5}\times \dfrac{3}{3}[/tex]
[tex]1\dfrac{2}{5}=-1\dfrac{6}{15}[/tex]
Now,
[tex]2\dfrac{1}{3}-1\dfrac{2}{5}=2\dfrac{5}{15}-1\dfrac{6}{15}[/tex]
[tex]2\dfrac{1}{3}-1\dfrac{2}{5}=(2+\dfrac{5}{15})-(1+\dfrac{6}{15})[/tex]
[tex]2\dfrac{1}{3}-1\dfrac{2}{5}=2+\dfrac{5}{15}-1-\dfrac{6}{15}[/tex]
[tex]2\dfrac{1}{3}-1\dfrac{2}{5}=1-\dfrac{1}{15}[/tex]
[tex]2\dfrac{1}{3}-1\dfrac{2}{5}=\dfrac{14}{15}[/tex]
Therefore, there is error in Frankie's last step. In that step, he did not subtract the mixed fraction correctly.

To get into the carnival, it costs $5. Then each ride costs $2.25. *Use a linear equation to solve the following:
If you brought $35, how many rides can you go on?
How much would it cost altogether to ride 7 rides?
Answer:
equation: y=2.25x+5
a: 13 rides
b:$20.75 for 7 rides
explanation:
a: 35=2.25x+5
first subtract 5 from 5 and 35
30=2.25x
divide each side by 2.25
x= 13 1/3
can only go on 13 rides
b: y=2.25(7)+5
2.25×7=15.75
15.75+5=20.75
$20.75 for 7 rides

What is the y-intercept of the line y + 6 = -4(X - 1.5)
Answer:
y=0.
y + 6 = -4(X - 1.5)
y+6 = -4x+6
y = mx+b
y=4x
There isn't a b, which is the y intercept, so the y int would be 0
A dance studio charges all new members a $175application fee plus $20 per month. How much will Stacie pay for a 2 year membership
Answer: Stacie will have to pay $655 for a 2 year membership
Answer:$655
Step-by-step explanation:
She has to pay 175 dollars upfront. So we know this amount will be added to what she pays. She pays 20 per month. If in two years there are 24 months, then you have to multiply 20 times 24, giving you 480. You have to then add the 480 and the 175, giving you 655. She will pay $655 for a 2 year membership.
Yusuf bought a DVD player for $280, now it is $220. What is the percent decrease in the price?
Answer:
About 21.4%
Step-by-step explanation:
280 - 220 = 60
60 of 280 = ?
Variable x = percentage
60/280 = x/100
Cross multiply
60 × 100 = 280 × x
6000 = 280x
Divide both sides by 280
6000 ÷ 280 = 280x ÷ 280
21.428.... = x
About 21.4%
Check work:
60/280 = 21.4/100
Cross multiply
60 × 100 = 280 × 21.4
6000 = 5992
6000 is close to 5992
It does not equal exactly 6000 because I estimated the percentage to 21.4% instead of 21.428....%

A grocery store clerk put only cans of tomato soup and cans of chicken soup on a shelf. The ratio of the number of cans of chicken noodle soup to the total number of cans on the shelf was 8 to 17. Which number could be the number of cans of tomato soup the clerk put on the shelf.
Answer:
9 cans of tomato soup
Step-by-step explanation:
We are told that only cans of tomato soup and cans of chicken soup are put on the shelf.
Now, we are told that the ratio of the number of cans of chicken noodle soup to the total number of cans on the shelf was 8 to 17.
In fraction, this is 8/17
Now, this implies that there are 8 cans of chicken noodle soup while there are a total of 17 cans on the shelf.
Thus,
Since only cans of chicken noodles and cans of tomato soup are on the shelf, it means;
Cans of tomato soup = 17 - 8 = 9
Answer:
9 Cans of Soup

Which set of lengths might be used to represent the sides of a right triangle?
A. (6, 7, 10)
B. (7, 15, 17)
C. (9, 12, 16)
D. (7, 24, 25)
Answer:
Step-by-step explanation:
B
The set of side lengths (7, 15, 17) represents a right angled triangle
For the given set of side lengths to represent a right angled triangle, the
Pythagoras relation should be satisfied by the side lengths of the triangle.
We can write the given relation as -
h² = b² + p²
Consider the side length pairs as -
(7, 15, 17)
We can arrange the sides as -
17² = 15² + 7²
289 = 225 + 49
289 = 289
The set of side lengths (7, 15, 17) represents a right angled triangle.
