Answer:
X=9 and Y=81
Step-by-step explanation:
For this case we have a system of two equations with two unknowns:
[tex]y = 9x\\y = 2x + 63[/tex]
Matching we have:
[tex]9x = 2x + 63[/tex]
subtracting 2x on both sides of the equation:
[tex]9x-2x = 2x-2x + 63\\7x = 63[/tex]
Dividing between 7 on both sides of the equation:
[tex]\frac {7x} {7} = \frac {63} {7}\\x = 9[/tex]
We find the value of y:
[tex]y = 9 (9)\\y = 81[/tex]
ANswer:
[tex]x = 9\\y = 81[/tex]

Ralph Kramer ingested $11,000 in a certificate of deposit for 1 year. The certificate earns interest at an annual rate of 5.75 percent compounded daily. The amount per $1.00 is 1.059180. What is the effective annual yield? Show work
Answer:
5.91%
Step-by-step explanation:
We are given an investment deposited fro 1 year compounded daily at an annual interest rate of 5.75%.
Compounding period per year, n: 365
The effective annual yield can be calculated by the following formula:
Effective Annual Yield = [tex] (1+\frac{r}{n})^{n}-1[/tex]
where n = 365
Interest rate, r= 5.75% = 0.0575
[tex]=(1+\frac{0.0575 }{365})^{365}-1[/tex]
= 0.059
The annual effective yield is 5.91%

Answers:
Rent = 750
Savings = 750
Groceries = 625 (you are correct)
Other = 375
========================================
Explanation:
Convert each percent to decimal form. You do this by moving the decimal point 2 spots to the left.
Rent has 30% turn into 0.30, which multiplies with 2500 to get 0.30*2500 = 750
For savings, the same multiplier is used because we also have 30% here as well. So the same amount is devoted to savings.
You have the correct answer for groceries. Multiply 0.25 with 2500 to get 625. Nice work on getting the correct answer here.
Finally, we have 15% devoted to other, so we multiply 0.15 by 2500 and we get 0.15*2500 = 375
As a check, we can add up the subtotals 750, 750, 625, 375 to get 750+750+625+375 = 2500 which helps us confirm our answers.
Answer:
Rent: $750
Savings: $750
Groceries: $625
Other: $375
Step-by-step explanation:
I used the formula: Part/Whole = Percent/100
So for the first two, since they are the same, I did x for the part, 2,500 for the whole, 30 for the percent, and 100. Then I did 30 times 2,500 and I got 75,000. Next I did 75,000 divided by 100 and got 750.
For "Groceries", I did the same thing except used x for the part, 2,500 for the whole, 25 for the percent, and 100.
For "Other", I did the same thing except used x for the part, 2,500 for the whole, 15 for the percent, and 100.

Boxes of Sticky Fingers popsicles are $4.50. The supermarket is offering a 30% off coupon. What is the price with the coupon? PLEASE HELP!!!!!!!
Answer:
The price of the popsicles are $3.15 with the coupon
Step-by-step explanation:
To find the price of the item, we need to find the discount
discount = price * percentage off
discount = 4.5 *.3
discount =1.35
New price = original price- discount
new price = 4.5 - 1.35
new price = 4.5 -1.35
new price = 3.15
The price of the popsicles are $3.15 with the coupon
Brianna has saved $32. 1/4 of the $ she earned from babysitting. How much $ did she earn babysitting?
Based on proportional standards, if $32 represents 1/4 of Brianna's total earnings from babysitting, then she earned a total of $128.
Explanation:From the amount Brianna saved, we know that $32 represents 1/4 or 25% of the total amount she earned from babysitting. If $32 is a quarter of the total amount, then we can find the total amount by multiplying $32 by 4. This is because 1 divided by 1/4 is equal to 4. So, Brianna earned a total of $32 x 4 = $128 from babysitting. This is the solution to the problem referred to as proportional reasoning. It involves understanding the concept of fractions and simple multiplication.

The amount of data left on a cell phone plan is 6 GB after 8 days. 1.5 GB of data is used each day. How much data is available at the beginning of the cycle?
Answer:
The answer is 18 GB
Step-by-step explanation:
Okay to the breakdown:
This is a word problem that requires basic knowledge of equality.
So lets say that the total amount of data at the beginning of the cycle is equal to X.
We are told that the data has been used for 8 days at a daily rate of 1.5GB per day, so the total data already used will be "Days × Rate" => 8 × 1.5 = 12GB.
We are also made to know that after the 8 days we still have 6 GB left out of the initial amount X.
Let put all the above in an equation:
X - 12 = 6;
Using the approach of putting liked them together we will add 12 to both sides:
X -12 + 12 = 6 + 12 => X = 18;
So the amount at the beginning of the cycle is 18 GB.

Part A: x=2
This would make both perimeters equal to 24.
Part B: No solution.
You cannot make x equivalent to anything but 2, or the square would not be real. All four sides of the square must equal 6. This would make the area 36 units squared. If x was 2 for the rectangle, the area would be 20. It is impossible to make them equal. Tell me if I'm wrong, though.
Kylie can afford a $1310-per-month house loan payment. If she is being offered a 25-year house loan with an APR of 8.4%, compounded monthly, which of these expressions represents the most money she can borrow?
Answer:
The most money she can borrow is $48478.7
Step-by-step explanation:
We are given
Kylie can afford a $1310-per-month house loan payment
so,
PMI=1310
t=25 years
n=12
APR=8.4%=0.084
So,
total money =(PMI)*t*n
[tex]A=1310\times 12\times 25[/tex]
[tex]A=393000[/tex]
now, we can use formula
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
we can plug values
[tex]393000=P(1+\frac{0.084}{12})^{12\times 25}[/tex]
now, we can solve for P
so, we get
[tex]P=\frac{393000\times \:12^{300}}{12.084^{300}}[/tex]
[tex]P=48478.7[/tex]
So,
The most money she can borrow is $48478.7

Ms. Salazar's rice mixture consists of five parts of white rice to two parts of wild rice. if she makes 21 cups of the mixture how many cups of white rice will she use?
Answer: 15 cups of white rice
Step-by-step explanation:
1. 5 cups of white to 2 cups of wild
2. 10 cups of white to 4 cups of wild
3. 15 cups of white to 6 cups of wild
4. 15 + 6 = 21
To determine the amount of white rice in a 21-cup rice mixture with a ratio of five parts white rice to two parts wild rice, we find out that one part is equivalent to 3 cups (since 21 divided by 7 is 3). Multiplying 3 cups by 5 parts of white rice gives us 15 cups of white rice.
Ms. Salazar's rice mixture consists of five parts of white rice to two parts of wild rice. To find out how many cups of white rice she will use for a 21-cup mixture, first, we need to determine the total number of parts in the mixture. Five parts white rice plus two parts wild rice equals seven parts total. Since Ms. Salazar is making 21 cups of the mixture, we will divide 21 cups by the total number of parts, which is 7, to find out the measurement of one part. After this, we multiply the measurement of one part by the number of parts of white rice, which is five.
21 cups / 7 parts = 3 cups per part
3 cups per part * 5 parts white rice = 15 cups of white rice.
So, Ms. Salazar will use 15 cups of white rice in her 21-cup mixture.
Which shows the correct substitution of the values a, b, and c from the equation –2 = –x + x2 – 4 into the quadratic formula?
The correct substitution of the values a, b, and c from the given equation into the quadratic formula is a = 1, b = -1, and c = -2, resulting in the formula x = [1 ± √(1 - 4(1)(-2))] / 2.
For the equation –2 = –x + x² – 4, we need to rewrite it in the standard quadratic equation form ax² + bx + c = 0.
First, rearrange the terms to get x² – x – 4 – (–2) = 0, which simplifies to x² – x – 2 = 0. Here, a = 1, b = -1, and c = -2.
Using the quadratic formula, x = [-b ± √(b2 - 4ac)] / 2a, we substitute a, b, and c:

Rose blew h bubbles in two hours. Which algebraic expressions shows how many bubbles she blew in one minute?
Answer:
I believe it is 2 / h = the amount she blew in 1 minute. Hope this helps
Answer:
h / 120
Step-by-step explanation:
2 hours equals 120 minutes.
So h bubbles in 120 minutes is h/120 per minute.
Verification: suppose she blew 240 bubbles in two hours; this would be 240/120 = 2 per minute. That makes 120 per hour and, as expected, 240 in two hours.

find value of x (5x) (3x + 28)
Final answer:
The question as posed does not provide a complete equation to solve for x. One would need to either expand the expression using distributive property or solve for x if it were part of an equation set to zero. Additional information is required to provide a definitive value for x.
Explanation:
The question appears to ask for the value of x when multiplied by the expression (5x)(3x + 28), however, it is incomplete as there is no equation to solve (i.e., no equals sign followed by a number). If you are meant to expand the expression, you would apply the distributive property to multiply 5x by both terms inside the parentheses, giving 15x^2 + 140x.
If the intention was to solve for x given an equation like (5x)(3x + 28) = 0, then you would set each factor to zero: 5x = 0 and 3x + 28 = 0. Solving these would give you x = 0 and x = -28/3 as the solutions.
Without a complete equation, we cannot definitively solve for the value of x. If additional information is provided or if you have a specific equation involving (5x)(3x + 28), please provide that for further assistance.
