the value of the x and y for the given system of equations are 6, and -2 respectively.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given, a system of equations
2x + 5y = 2
2x - 5y = 22
Adding both equations:
4x = 24
x = 6
From equation 1
2 * 6 + 5y = 2
5y = -10
y = -2
Therefore, the value of the x and y for the given system of equations are 6, and -2 respectively.

On a scavenger hunt, you find 16 out of 20 objects. Write "16 out of 20" as a fraction in simplest form, a decimal, and a percent.
Answers
Decimal: 0.8
Percentage:8
Hi there, here's your answer:
According to the question, we find 16 out of 20 objects.
To express this in a fraction at its simplest form,
We first write down the fraction.
[tex]\frac{16}{20}[/tex]
The HCF of 16 and 20 is 4.
On dividing the numerator and denominator by 4, we get: [tex]\frac{4}{5}[/tex]
To express [tex]\frac{4}{5}[/tex] as a decimal:
Observe the denominator. We know that 5×2 = 10
On multiplying the numerator and denominator by 2, we get [tex]\frac{8}{10}[/tex]
Which, in decimal form, is 0.8
To express [tex]\frac{16}{20}[/tex] as a percentage,
We simply multiply the fraction by 100.
[tex]\frac{16}{20}[/tex] × [tex]100[/tex] [tex]= 16[/tex] × [tex]5 = 80[/tex]%
Therefore, 16 out of 20 in percentage is written as 80%.

Suppose you have two bank accounts. In Account A you deposit $100. In Account B you deposit $300. Account A has a simple interest rate of 4.3%. Account B has a simple interest rate of 2.1%. One year later, you get a bank statement from each bank and one of the statements shows an incorrect amount of interest. The interest for Account A is $4.30. The interest for Account B is $630. Which account statement is incorrect? Find the bank's likely error.
Answers
The interest for Account B is likely incorrect.
The interest for Account A can be calculated as follows:
$100 * 4.3% = $4.30
The interest for Account B should be calculated as follows:
$300 * 2.1% = $6.30
Since the interest for Account B is much higher than it should be, the statement from that account is likely incorrect. The bank's likely error is overstating the interest earned on Account B.

(a) Reflect the point (7,9) across the x-axis
(b) Reflect the point (7,9) across the y-axis
Answers
(b) When we reflect (7,9) across the y-axis, we would get (-7,9)
I got my answer by understanding the reflection graph rule:
When you reflect a point across the x-axis, the x-axis will stay the same; however for the y-axis, we have to change the sign to its opposite. The term “reflect x-axis” means that we go across the x-axis. Therefore the x-axis stays the same, while the y-axis sign changes.
When you reflect a point across the y-axis, the y-axis will stay the same; however for the x-axis, we have to change the sign to its opposite. The term “reflect y-axis” means that we go across the y-axis. Hence why the y-axis stays the same, while the x-axis sign changes.
Reflect the point (-3,-8) across the y-axis
Reflect the point (-3,-8) across the x-axis
Answers
Step-by-step explanation:
When reflecting a point across an axis, that means the opposite coordinate will switch signs.
Reflecting a point across the YAXIS means that the X coordinate will switch signs
Reflecting a point across the XAXIS means that the Y coordinate will switch signs
Taking (-3, -8)....
Reflecting it across the y-axis, we will flip the sign of the X coordinate. It's -3, so we make that +3, giving us
(3, -8)
Reflecting across the x-axis, we will flip the sign of the Y coordinate. it's -8, so we make that +8, giving us

Calculate the area of the annulus which has an external diameter of 25cm and an internal diameter of 15cm
Answers
Answer:
314.159 square cm
Step-by-step explanation:
Area of an annulus with external radius r1 and internal radius r2 is given by
π(r1² - r2²)
radius = half diameter
r1 = 25/2 = 12.5 cm
r2 = 15/2 = 7.5 cm
Area of annulus
= π(12.5² - 7.5²)
= 314.159 square cm
The correct answer is 314.159 square cm

The radius of the base of the cone is √189 ft.
What is the Pythagorean theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The theorem can be used to determine how steep mountains or slopes are. To calculate the distance between an observer and a location on the ground when the observer is looking down from a tower or structure. It is mostly utilized in the construction industry.
For question 5 :
Given a right-angle triangle that has a hypotenuse of 14 and a base is 9 cm.
From the Pythagorean theorem:
Hypotaneuse² = base² + height²
14² = 9² + height²
height² = 196 - 81
height² = 115
height = √115
For question 4:
The distance from the top of the cone to the edge is 15 feet. The height of the cone is 6 feet.
The radius of the cone = base pf right angle triangle
From the Pythagorean theorem:
Hypotaneuse² = base² + height²
15² = base² + 6²
225 - 36 = base²
base = √189

Apollo traveled 54 leagues in 3 days. Then he tripled his rate. How long would it take him to travel 594 leagues at this new speed?
Answers
Answer:

18 x 3 = 54
594 ÷ 54 = 11
You have 2 different savings accounts. For Account A, the simple interest earned after 9 months is $6.75. For Account B, the simple interest earned after 21 months is $19.25. If the interest rate is 3.6% for Account A and 2.2% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
Answers
Answer:
Account A Principal: $250
Account B Principal : $500
Account B earned $0.17 more interest in the first month
Step-by-step explanation:
Let the principal in account A be PA and the principal in account B be PB
Simple interest I = Prt where P is principal, r is interest rate (in decimal) and t - time in years
Therefore, given interest I
P = I/rt
We will assume both interest rates are annual interest rates
For account A, interest = 3.6% per year
This works out to 0.036 per year
For account B, interest = 2.2% which works out to 2.2/100 per year = 0.022 per year
Account A
I = 6.75, r = 0.036 t = 9 months = 9/12 year = 3/4 year = 0.75 year
PA = 6.75/(0.036 x 0.75) = $ 250.00
Account B
I = 19,25, r = 0.022, t = 21/12 = 1.75 years
PB = 19.25/(0.022 x 1.75) = P = $ 500.00
Account A interest earned per month = 6.75/9 = $0.75
Account B interest earned per month = 19.25/21 = $0.92
Hence account B earned more interest in the first month
The amount of interest earned by account B over account A
= 0.92 = 0.75 = $0.17

Emily noticed that on halloween, her child got three basic types of candy: chocolate, gummy, and hard candy. She has 15 more hard candies that chocolate, and 5 less than twice the amount for gummy candy than chocolate. if she had a total of 178 pieces of candy, how many of each type did she get?
Answers
Answer: gotta scroll down sry
Step-by-step explanation:
First set up equations with variables that show the information you have:
c = chocolate // g = gummy // h = hard candy
178 = c + g + h
h = c + 15
g = 2c - 5
Then, solve all the equations for a number:
178 = c + g + h (leave as is)
15 = -c + h (subtract 'c' from the original equation's right side and switch the sides of the equation)
-5 = -2c + g (subtract '2c' from the original equation's right side and switch the side of the equation)
Then, line up all the variables and subtract the top equation by the lower two:
178 = c + g + h
15 = -c + 0g + h
-5 = -2c + g + 0h
---------------------------
168 = 4c + 0g + 0h >>>> 168 = 4c
Solve for 'c' and plug it into the other equations to find 'h' and 'g':
168/4 = 4c/4
42 = c
15 = -(42) + h -5 = -2(42) +g
57 = h 79 = g
Add all the numbers together to double-check:
42 + 57 + 79 = 178
chocolates = 42
gummies = 79
hard candies = 57

Since we know these figures are cubes, we only need to know the length of one side, 4. To find Cube A’s volume, we multiply 4 times 4 times 4 to get 64. Cube A has a volume of 64³ cm.
We know Cube B’s sides are twice as long as Cube A, so they have to be 8 cm. 8 times 8 times 8 is 512. Cube B has a volume of 512³ cm.
