Devaughn is 11 years older than Sydney. The sum of their ages is 53 . What is Sydney's age?

Answer:

x = 3, y = 7

Step-by-step explanation:

Since we already have y's value, we can plug y into the bottom equation to get 3(5x - 8) = x + 18. We can distribute 3 into 5x and 8 to get 15x - 24 = x + 18. We can now subtract x from the both sides to get all terms on one side to get 14x - 24 = 18. We can now add 24 to both sides to get 42. We can now divide both sides of the equation by 14 to get x = 3. We can plug x into the top equation to get y = 5(3) - 8. We can multiply 5 and 3 together to get y = 15 - 8. We can simplify and subtract to get y = 7. Our final answer is (3, 7)

What is X?

I say that X = 2

Answer:

3 litros

Step-by-step explanation:

Joana alugou um carro para fazer uma viagem de 36km sabendo que o carro percorre 12 km cm 1 litro custa

Da pergunta:

12 km = 1 litro

36km = x

Cross Multiply.

12x = 36 × 1

x = 36/12

x = 3 litros

Where is the question?

Answer: There are 375 star stickers and 125 heart stickers.

There are 500 stickers with 20 stickers per sheet; 500/20 = 25 sheets of stickers.

25% of each sheet is hearts; 25/100(20) = 5 heart stickers per sheet.  5(25) = 125 total heart stickers.

20 stickers per sheet - 5 heart stickers per sheet = 15 star stickers per sheet.  15(25) = 375 total star stickers.

Answer:House=4,225ft^2

Step-by-step explanation:

(15)^2+100(15)+2,500

=225+1,500+2,500

=4,225

(a) The area of the house is [tex]x^2+100x+2500 \; \; ft^2[/tex]

(b) Area of the extension

House =4225 ft^2

Important information :

The area of the house is represented  by quadratic expression

[tex](x+50)^2[/tex]

To find out the product to multiply x+50 twice

[tex](x+50)(x+50)[/tex]

Apply FOIL method to multiply the parenthesis

[tex](x+50)(x+50)\\x^2+100x+2500[/tex]

The area of the house is [tex]x^2+100x+2500 \; \; ft^2[/tex]

(b) given x=15. To find area of extension , we replace x with 15 in the answer we got from part (a)

[tex]x^2+100x+2500 \\x=15\\(15)^2+100(15)+2500 \\225+1500+2500\\4,225[/tex]

Area of the extension

House =4225 ft^2

Answer:

yes it is possible to make a triangle with those lengths.

It is possible to form a triangle with the given side lengths

A triangle is a two-dimensional geometrical figure that has three sides, three vertices and three interior angles.

Given, three sides are 7 yards, 8 yards, 9 yards.

Let, three sides are 'a', 'b, 'c' and 'a' is the largest among these three.

Then, a triangle can be formed with these three sides if (b + c)>a.

Here, 9 yards is the largest.

Therefore, (7 + 8) yards = 15 yards > 9 yards

Therefore, with these three sides, a triangle can be formed.

The square footage of the home is 1800 sqft

Area of rectangle is defined as the product of its length and width.

Let suppose two separate rectangles. Calculate area as length x width. Here’s that shows

1: 40x25 = 1000

2: 20x40 = 800

After that we calculate the square footage of each by adding them up to it’s sum.

Total = 1800 sqft

Hence, the square footage of the home is 1800 sqft

Step-by-step explanation:

Answer:

1kg stone is heavy so it is weight

Answer:

Rs 1,073.56

Step-by-step explanation:

The computation of the compound interest is shown below:

Compound interest = Principal (1 + rate of interest)^time period - Principal

= Rs 10,000 × (1 + 17 ÷ 2%)^1.25 - Rs 10,000

= Rs 10,000 × (1 + 0.085)^1.25 - Rs 10,000

= Rs 11073.56 - Rs 10,000

= Rs 1,073.56

so lets see the calculation ：

Since he bought 5 kg wheat at rs. 38.50 per kg then total will be = 5* 38.50 = Rs. 192.5

also he bought 3 coconuts at rs. 30 per piece then total will be = 3* 30 = Rs. 90

Also ,

He bought 1 Dettol at Rs 52.25

Then total will be ：

Rs. 52.25 + 90 + 192.5

Answer:

Part A

0.764 minutes/miles

Part B

48.4 minutes

Step-by-step explanation:

a) Jasmine ran 55 miles in 42 minutes. Part A At what rate did Jasmine run?

​Jasmine ran at a rate of minutes per mile. ​

Rate = Minutes/Miles

Minutes = 42 minutes

Miles = 55 miles

Jasmine's rate = 42 minutes/55 miles

= 0.7636363636 minutes/miles

Approximately = 0.764 minutes/miles

Part B

Katie ran 44 miles. She ran at a rate that was 1.1 minutes per mile slower than Jasmine. For how many minutes did Katie run? Explain how you determined your answer. ​ ​

Rate = Minutes/Miles

Minutes = ?

Miles = 44 miles

Rate = 1.1 minutes per miles

Hence:

1.1 minutes per miles = x/44 miles

x = 1.1 minutes per miles × 44 miles

x = 48.4 minutes

43 * .20 = 8.6 this is the discount

So subtract the discount from the price to get

43.00-8.60= $34.40

Answer:$647

Step-by-step explanation:

293+(59*6)=

293+454=

647

First start off with 293

Now multiply 59 by 6 because 6 is how many hours they will rent it for.

59 x 6 = 354

After that add the 354 to the 293 we had before.

293 + 354 = 647

So the cost of the ball room would be 647 dollars.

It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

4. Yes

Step-by-step explanation:

Plug in values for the unknowns into bother expressions to see if the give the same answer.

I don't really know how to do this but the best thing I can say is to replace those variables with a number and then put it in a calculator. Make sure each variable has a different number.

so for the first one, I made s as 2 and t as 3. I got 18 for the first one and 6 on the other one so they're clearly not equal.

good luck!
