Answer:
x = 2
y = 2
Step-by-step explanation:
x + 8y = 18
-5x + 3y = -4
multiply entire first equation by 5 to get
5x + 40y = 90
add second equation
5x + 40y = 90
+(-5x + 3y = -4)
----------------------------
43y = 86
y = 2
plug it in now
x + 8(2) = 18
x = 2
-5x + 3(2) = -4
x = 2

Shane, Cheryl, and Isaac went to the store to buy school supplies. Shane bought 4 pens, 3 folders, and 2 notebooks for a total of $12.25. Cheryl bought 4 folders and 6 notebooks for a total of $22. Isaiah bought 2 pens, 1 folder, and 3 notebooks for a total of $10.25. How much does each supply cost? Each pen costs $(1.25 0.50 0.75 1.75). Each folder costs $(2.75 1.75 2.50 1.25). Each notebook costs $(2.75 1.75 2.50 1.25).
Answers
The cost of each entity: each pen is $[tex]1.75[/tex], each folder is $[tex]2.50[/tex], and each notebook is $[tex]1.75[/tex].
Let's assign variables to the costs of each supply:
Let the cost of each pen be P dollars.
Let the cost of each folder be F dollars.
Let the cost of each notebook be N dollars.
According to the given information, we can form the following equations:
For Shane:
[tex]4P + 3F + 2N = 12.25 (Equation \ 1)[/tex]
For Cheryl:
[tex]4F + 6N = 22 (Equation \ 2)[/tex]
For Isaiah:
[tex]2P + F + 3N = 10.25 (Equation \ 3)[/tex]
To solve this system of equations, we can use substitution or elimination method.
Using the elimination method, let's multiply Equation 2 by 2 and Equation 3 by 4 to eliminate F:
[tex]8F + 12N = 44 (Equation \ 4)\\8P + 2F + 12N = 41 (Equation \ 5)[/tex]
Now, subtract Equation 4 from Equation 5 to eliminate F:
[tex]8P + 2F + 12N - (8F + 12N) = 41 - 44\\8P - 6F = -3[/tex]
Simplifying further, we have:
[tex]8P - 6F = -3 (Equation \ 6)[/tex]
Now, let's multiply Equation 1 by 4 and Equation 3 by 3 to eliminate N:
[tex]16P + 12F + 8N = 49 (Equation \ 7)\\6P + 3F + 9N = 30 (Equation \ 8)[/tex]
Now, subtract Equation 8 from Equation 7 to eliminate N:
[tex]16P + 12F + 8N - (6P + 3F + 9N) = 49 - 30\\10P + 9F - N = 19[/tex]
Simplifying further, we have:
[tex]10P + 9F - N = 19 (Equation \ 9)[/tex]
Now we have a system of equations consisting of Equation 6, Equation 9, and Equation 2:
[tex]8P - 6F = -3 (Equation \ 6)\\10P + 9F - N = 19 (Equation \ 9)\\4F + 6N = 22 (Equation \ 2)[/tex]
To find the values of P, F, and N, we can solve this system of equations using any suitable method, such as substitution or elimination.

3) Jerry has $400 saved in his bank account and spends $15 a week.
Jack has $230 and saves $5 a week. After how many weeks will Jerry
and Jack have the same amount in their bank accounts?
Answers
Answer:
No
Step-by-step explanation:
Jerry - 15 x 7 = 105
400 - 105 = 295
Jerry will have 295 in his account
Jack- 5 x 7 = 35
230 + 35 = 265
Jack will have 265 in his account
So no they will not have the same amount in both of their banks

The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 31 m. Find the height of the building. If
necessary, round your answer to the nearest tenth.
Answers
Answer:
16.9 m
Step-by-step explanation:
The diagram given that represents this situation is a right triangle.
The height of the building can be found using the pythagorean theorem, a² + b² = c².
Where,
a = 26 m
b = height of the building = h
c = 31 m
Plug in the values into the formula
Thus:
[tex] 26^2 + b^2 = 31^2 [/tex]
[tex] 676 + b^2 = 961 [/tex]
Subtract 676 from each side
[tex] b^2 = 961 - 676 [/tex]
[tex] b^2 = 285 [/tex]
Square both sides
[tex] b = \sqrt{285} [/tex]
[tex] b = 16.9 m [/tex] (nearest tenth)

Step-by-step explanation:
The equation is 30 x 2927 - 927 ÷ 3 + 8
You would first multiply 30 and 2927 to get 87810 - 927 ÷ 3 + 8
Then you would divide 927 by 3 to get 87810 - 309 + 8
Then you subtract 309 from 87810 to get 87501 + 8

Why do most student loans involve a co-signer? a. Most students won’t be able to afford paying for their loans, and leave that responsibility to their co-signers. b. Co-signers were most likely college students themselves and understand what it is like to be a college student. c. Most students aren’t responsible enough to know much about any type of loans, so a co-signer is there to make sure everything is secure. d. Most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.
Answers
Answer:
d. Most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.
Step-by-step explanation:
A student loan can be defined as a governmental loan or loan sourced from a private lender in order to help a student pay his or her college or university expenses such as tuitions, books, living costs and supplies.
Also, a co-signer refers to an individual who agrees to apply for a loan with a student and as such is saddled with the responsibility of repaying the loan if the student cannot pay or defaults in the repayment of the loan.
This ultimately implies that, a co-signer is legally liable for the loan applied for by the student (borrower), if he or she cannot pay because the co-signer has been confirmed to have a good credit score and credit history.
Hence, the reason most student loans involve a co-signer is because most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.
Answer:
D. Most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.

un vaso contiene leche hasta los 3/5 de su capacidad. si echa un 1/7 mas, es seguro que la leche
A.se derramara porque supera el 100% de la capacidad del vaso
B.no se derramara porque no supera el 50% de la capacidad del vaso
C.se derramara porque la cantidad total es equivalente a la capacidad de dos vasos
D.no se derramara porque la cantidad total esta entre el 70% y el 80% de la capacidad del vaso
Answers
Answer:
De las opciones presentadas, la correcta es la D.
Step-by-step explanation:
Suma de fracciones
Dado que un vaso contiene 3/5 de su capacidad con leche, aún tiene libre una fracción que puede ser llenada.
Si se echa 1/7 más de leche, vamos a encontrar si la suma de las dos cantidades supera al 100% o también al número 1 que es la representación del vaso completo.
Sumemos:
[tex]\displaystyle \frac{3}{5}+\frac{1}{7}=\frac{3*7+1*5}{35}=\frac{21+5}{35}=\frac{26}{35}[/tex]
Como el numerador es menor que el denominador, la fracción es menor que 1 y aún cabe más leche en el vaso. Calculando el valor aproximado:
[tex]\displaystyle \frac{26}{35}\approx 0.74[/tex]
Lo cual representa un 74% aproximadamente.
De las opciones presentadas, la correcta es la D.
