How Do You Solve This ?

Answers

Answer 1

Answer:

3y

Step-by-step explanation:

Simplifying

13x + -39y = 0

Solving

13x + -39y = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '39y' to each side of the equation.

13x + -39y + 39y = 0 + 39y

Combine like terms: -39y + 39y = 0

13x + 0 = 0 + 39y

13x = 0 + 39y

Remove the zero:

13x = 39y

Divide each side by '13'.

x = 3y

Simplifying

x = 3y

One hot Saturday, Richard scooped 234 regular cones and 156 large cones. One scoop of ice cream is 3 ounces. A tub of ice cream weighs 10 pounds. How many tubs of ice cream did Richard use to make the cones?

Answers

Answer:

18

Step-by-step explanation:

The total number of scoops of ice cream that Richard got from the tub is,

  (234 regular cones) x (2 scoops / 1 regular cone) + (156 large cones) x (2 scoops / 1 large cone) = 936 scoops


Given that each scoop weighs 3 ounces, the total weight of the ice cream is 2808 ounces. For the number of tubs,

         (2808 ounces) x (1 lb / 16 ounces) x (1 tub /10 lb) = 17.55

Thus, the answer is 18.

what is the value of x in the diagram below ?

Answers

Answer:

x = 9

Step-by-step explanation:

12^2 + a^2 = 54^2

a^2 = 54^2 - 12^2

a = sqrt (54^2 - 12^2) = 6 * sqrt(77)

Then calculate it for another triangle, where each side is 6 times shorter (as 12/2 = 6):

2^2 + (sqrt(77))^2 = x^2

x^2 = 81

Find the slope of the line represented by the table of values.
A) −4
B) −1/4

C) 4
D) 1/4

Answers

Answer:

B) −1/4


Step-by-step explanation:

The slope represents the change in y values divided by the change in x values.  We can use the formula

slope = (y2-y1)/(x2-x1)

(2,4)  (-2,5)

slope = (5-4)/(-2-2)

        = 1/-4

slope = -1/4

Answer:

B. -1/4

Step-by-step explanation:

To get the slope you have to use the formula: y2-y1/x2-x1

y2-y1/x2-x1 = 4.47-5/-1-(-2)

4.75-5 = -.25

-1 - (-2) = 1

-.25/1 = -.25 or -1/4

Father gave me some money. I could choose between 15% of 1,500$ or 25% of 1,000$. Which amount did I choose

Answers

Answer:

25% of 1000 > 15% of 1500

Step-by-step explanation:

Lets calculate how much money you could receive

15% of 1500

.15 * 1500 = 225


25% of 1000

.25*1000 = 250


250>225

Final answer:

After calculating 15% of $1,500 and 25% of $1,000, it is evident that choosing the latter provides more money, amounting to $250 compared to $225 from the former option.

Explanation:

Choosing between percentages of different amounts involves straightforward arithmetic. To determine which option gives you more money, calculate the numerical value of each percentage. Option one is 15% of $1,500, which can be calculated as follows:

Convert the percentage to a decimal: 15% = 0.15.

Multiply the decimal by the total amount: 0.15 x $1,500 = $225.

Option two is 25% of $1,000:

Convert the percentage to a decimal: 25% = 0.25.

Multiply the decimal by the total amount: 0.25 x $1,000 = $250.

Now, compare the two amounts: $225 from the first option and $250 from the second option. It is clear that you would receive more money by choosing the 25% of $1,000, as it gives you a total of $250 compared to the $225 from the first option.

Eliza travels 6 times as many minutes to school as ricky does.Altogether,they travel 63 minutes each day.How many minutes does Eliza travel?

Answers

Answer:

Eliza travels 54 minutes.

Step-by-step explanation:

Let's use the variable r to represent the number of minutes Ricky travles to school.

Eliza travels 6 times as many minutes as Ricky, so Eliza travels 6r minutes.

Altogether, they travel r + 6r minutes, or 7r minutes.

We are told they travel 63 minutes altogether, so 7r must equal 63.

7r = 63

Divide both sides by 7.

7r/7 = 63/7

r = 9

Ricky travels 9 minutes.

Eliza travels 6r minutes.

6r = 6 * 9 minutes = 54 minutes

Eliza travels 54 minutes.

Joe borrowed $9,000 from the bank at a rate of 7% simple interest per year. How much interest did he pay in 2 years?

Answers

Final answer:

Joe paid $1,260 in interest over 2 years.

Explanation:

To calculate the amount of interest Joe paid in 2 years, we can use the formula: Interest = Principal * Rate * Time. In this case, the principal is $9,000, the rate is 7% (which is equivalent to 0.07), and the time is 2 years. Plugging these values into the formula gives: Interest = $9,000 * 0.07 * 2 = $1,260. Therefore, Joe paid $1,260 in interest over 2 years.

A line passes through the point , ( − 6, 1) and has a slope of − 4/3 .

Answers

Final answer:

A line with a slope of -4/3 passes through the point (-6, 1) can be represented by the equation y = -4/3x - 7.

Explanation:

A line with a slope of -4/3 passes through the point (-6, 1).

To find the equation of the line, we can use the point-slope form of a linear equation: y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope.

Substituting the values into the equation, we get y - 1 = -4/3(x - (-6)).

Simplifying, we have y - 1 = -4/3(x + 6).

Expanding, y - 1 = -4/3x - 8.

Moving the constant term to the other side, we get y = -4/3x - 7.

Under the dilation, the point (-3, -4) is moved to (-15, -20)
what is the scale factor of the dilation?

Answers

Answer:

The scale factor of dilation is: 5

Step-by-step explanation:

" A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

If the scale factor is greater than 1, the image is an enlargement (a stretch) " .

Whenever we multiply an coordinates or for some figure if all the coordinates get multiply by same factor 'a' then 'a' is called as scale factor in the dilation.

Here in this question:

(-3,-4) is moved to (-15,-20).

Here when (-3,-4) is multiplied by 5 we get the coordinate as: (-15,-20).

Hence, the scale factor is 5.

Step-by-step explanation:

the terms form a geometric sequence with

common ratio r = [tex]\frac{-72}{24}[/tex] = [tex]\frac{24}{-8}[/tex] = - 3

to obtain the next term in the sequence multiply the previous term by r
