One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I will be twice as old as my brother.” How old are they each now?

if you can figure it out i will give brainiest

Answers

Answer 1

Let us suppose two years ago my brother's age was x years

Then, my age was 3x

Three years from now, my brother's age will be (x +2+3) = (x+5) years

And my age will be (3x+2+3) = (3x+5) years

But it is given that i will be twice as old as my brother.

So, 2(x+5)= (3x+5)

or, x= 5 years

So my brother's present age is 5+2= 7 years

And my age is 5*3+2= 17 years

Answer 2
2 years ago -
younger brother was 5
he was 15

= 5 x 3 = 15



now -
younger brother is 7
he is 17



3 years time -
younger brother is 10
he is 20

= 10 x 2 = 20




answer is 7 & 17

10 points if solve, will give brainliest to the correct answer. please explain I really need help with solving percentages, ( Thanks SO MUCH!)
* THANKS!*

Answers

Answer:

25% of the milkshakes had whipped cream.

Step-by-step explanation:

Belle's Diner sold 8 milkshakes with whipped cream and 24 milkshakes without whipped cream. Given this information, we can add these two numbers to identify the total number of milkshakes Belle's Diner made:

[tex]8+24=32[/tex]

Belle's Diner made 32 milkshakes in total.

To find the percentage of milkshakes that had whipped cream, simply divide the number of milkshakes that had whipped cream (8) by the total number of milkshakes (32):

[tex]\frac{8}{32} =.25[/tex]

.25 as a percentage is 25% (move the decimal point two decimal places to the right).

Answer:

25% of the milkshakes have whipped cream on top.

Step-by-step explanation:

24+8=32

8/32=.25

*Note: To get the decimal form of any fraction you divide the numerator by the denominator.

.25 = 25%

A fifteen passenger van is rented for a family vacation. The van rental is $75.00 per day, plus a $160.00 insurance fee. Which equation could be used to find x, the number of days the car be rented if they want to spend exactly $760.00 on the van rental?

A. 75.00 + 160.00x = 760.00
B. 75.00x – 160.00 = 760.00
C. 75.00 – 160.00x = 760.00
D. 75.00x + 160.00 = 760.00

Answers

Answer:

D. 75.00x+160.00=760.00

Answer:

Letter D.

Step-by-step explanation:

Since I believe we are trying to decipher the number of days the car must be rented if they want to spend exactly 760.00$, you must multiply the number of days by the rental price and add the fee. So, let’s test it out!

160.00 = 760.00

-160.00 -160.00 = 600.00

and then,

75.00x = 600.00

———. ———-

75.00 75.00 = 8

Enter your answer as the correct number of degrees, like this: 42
HELP PLEASEEEEEE

Answers

Answer:

156°

Step 1: Create an Equation Using the idea (Angle B + Angle C = 180°)

=> 14x + x = 180°

Step 2: Solve.

=> 14x + x = 180°

=> 15x = 180°

=> x = 12°

Step 3: Multiply 12 by 14.

=> 12 x 14 = 168°

Step 4: Subtract 168 by 12.

=> 168 - 12

=> 156°

Final Answer:

After working on this problem, we can conclude that the difference between Angle B and Angle C is 156°

A doctor's office found that a lower outside temperature did not indicate a change in the number of appointments made. What can we determine from this information? 1.There is no correlation between outside temperature and number of appointments made. 2.There is a correlation between outside temperature and number of appointments made. However, there is no causation. This is because there is likely an increase in the number of appointments made with a decrease in the temperature outside. 3.There is a correlation between outside temperature and number of appointments made. There may or may not be causation. Further studies would have to be done to determine this.

Answers

Answer: 1, There is no correlation between outside temperature and number of appointments made.

Step-by-step explanation: It would be 1 because in the problem it states that even though temperatures were lower outside, their number of appointments had not changed. Because the number of appointments had not changed, there is no correlation between the temperature outside and number of appointments made.

Answer:

no correlation

Find the value of x in the following diagrams (I drew them instead)

Answers

Answer:

1)  51°      2)     _?_     3) 55 ⁰          4) 30°

Step-by-step explanation:

3) First you find out what is G which = 90⁰, And then add the 90 and 75.

Then we will make this equation : (90+75) - 360 ( because Angle Sum property = Sum of all angles from the inside = 360⁰)

Then we do that which will be = 185-360

                                                   =  175

The we plus all the x's = x + 2x

                                        = 3x

then our equation is =    3x= 175

                                   x = 175/3  (Because of Transposition )

                                    x= 55°

And Then we do add and multiply

Like This: x=55

               2x= 2x55 = 110°

1) First add 67 and 62

Then our equation= (67+62)-180 ( Because of Interior angle sum property of triangles = sum of all interior angles = 180°)

Then = 129 - 180

         = 51 °

And then because of opposite angle are equal so our x= 51° because our angle in the triangle above x = 51° so it will be equal opposite (hope you understand)

4) First add 2x+4x

    Our Equation= (2x+4x)=90° (be cause right angle = 90°)

                          =     6x=90              

                            x =90/6

                              x = 15°

So, 2x= 2 x 15 = 30°

     4x = 4 x 15 = 60°

At the movies, you order 3 boxes of popcorn and a bottle of water. The cost of the bottle of water is $1.75. Your total cost is $9.25. Write an EQUATION to find the cost of one box of popcorn.

Answers

3 boxes of popcorn and a bottle of water are $9.25
A bottle of water is $1.75

$9.25 - $1.75 = $7.5 (the price of 3 boxes of popcorn)
We divide $7.5 by 3 to know the price of one box of popcorn
$7.5 : 3 = $2.5
One box of popcorn costs $2.5

Answer:

Step-by-step explanation:

$9.25-$1.75=7.5

now you divide 7.5 by the number of popcorn have brought

$7.5 divided by 3= $2.5
