Because you can multiply across the numerator and denominator.
2 4 8
—- x —- = —-
8 5 40
2•4=8
8•5=40

find the x helpp pleaseee

Answers

you can solve this using pythagoras theorem which states that the sum of the square of the lengths of the sides adjacent to the right angle is equal to the square of the length of ypotenuse (hypotenuse is the longest side which is opposite to right angle)

( the attached image will help you understand the theorem better)

so

20² + 15² = x²

400 + 225 = x²

625 = x²

√625 = x

25 = x

X=25

what does scholarship mean to you? (must use at least 1 paragraph

Answers

A scholarship is an opportunity of a lifetime for someone who might be otherwise unable to attend a college or university. For me it is motivation to strive in my education process and always reach for higher goals. It is an ability for me to achieve my dreams and it is awarded to me through my ambition, heart, and motivation.

(you might want to tweak this to fit you and make it longer but this is the best i got)

I think a scholarship means an opportunity for people to earn an education. Without assistance from an outside source, students may have trouble paying for the degree. Scholarships help students have more time to focus on their studies. For many students, the stresses of working make it difficult for them to graduate on time, or graduate with the high grades they have the potential to achieve. For other students, the work/study life is unsustainable, and they discontinue their studies altogether. And I think scholarships can fill the gap. I feel with the assistance it can support students who fall in the gap between high and low-income levels.

A certain type of bacteria reproduces so that after x hours there are 15x cells. What single power represents he size relationship between the cell population after 24 hours and the cell population after 8 hours? Show your work

Answers

Answer:

let's say cells is c and hours are x that means there are 15 cells each hour. the equation for that is c=15x

after 08 hours the cells have multiplied 8 times their original size. meaning that the equation changes to this: c=15x          x=8    c= 15(8)

x equals 8 at that time.. literally

ok the cells have multiplied and now there are 120 cells in total

then after one day the cells have multiplied over 12 times afterwards. now x equals 24. the equation would look a little like this:

c=15x      x=24    c= 15(24)

there are 360 cells now.

Explain in your own words the relationship between x=8 with x=24 in the equation.

4x+3y=16
x=-3y+13

Answers

Step by Step Solution
More Icon
System of Linear Equations entered :

[1] -4x - 3y = -7
[2] 16x - 3y = 13
Graphic Representation of the Equations :

-3y - 4x = -7 -3y + 16x = 13



Solve by Substitution :

// Solve equation [2] for the variable x


[2] 16x = 3y + 13

[2] x = 3y/16 + 13/16
// Plug this in for variable x in equation [1]

[1] -4•(3y/16+13/16) - 3y = -7
[1] - 15y/4 = -15/4
[1] - 15y = -15
// Solve equation [1] for the variable y


[1] 15y = 15

[1] y = 1
// By now we know this much :

x = 3y/16+13/16
y = 1
// Use the y value to solve for x

x = (3/16)(1)+13/16 = 1
Solution :
{x,y} = {1,1}

Answer:

 x=1   y=4

Step-by-step explanation:

1.  4x+3y=16

   x=-3y+13

2. 4x+3y=16

    x+3y=13

3.  4x+3y=16

     -x-3y=-13

4.  3x=3

5.   x=1

6. (1)=-3y+13

7.  1-13=-3y

14.83


17.09

Answers

Answer:

14.83

Step-by-step explanation:

We can use the Pythagorean theorem to solve the question

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

6^2 + DE ^2 = 16^2

36+ DE ^2 = 256

Subtract 36 from each side

DE ^2 = 256-36

DE ^2 = 220

Taking the square root of each side

sqrt( DE^2) = sqrt(160)

DE =14.83239697

Rounding to the nearest hundredth

DE =14.83

14.83 is the answer buddy

The 7th grade basketball team won 9 out of 15 games. What is the ratio of losses to wins?

Answers

3:5 is the ratio i’m pretty sure

Answer:

The ratio of losses to wins is 6:9 or if simplified 3:2

Step-by-step explanation:

The 7th grade basketball team played 15 games in total. If they had 9 out of those 15 games they lost the other 6. So, the ratio of losses to wins is 6:9. Losses goes first because its first in the word problem. To simplify a ratio find the number they both divide into. In this case its 3. 6 divided by 3 is 2. And 9 divided by 3 is 3. So in simplest form the answer is 3:2 :)

Oliver has 5 pieces of string that are each 4 2/12 feet long. Destiny has 4 pieces of string that are each 5 14/16 feet long. Use an estimation strategy to determine who has the most string. Choose the name and number to complete the statement. Choose..(Oliver or Destiny) is estimated to have Choose...(1 through 10) more feet of string.​

Answers

Answer:

Destiny is estimated to have around 4 more feet of string.

Step-by-step explanation:

Oliver:

4 2/12 is rounded to 4.

5x4=20.

Destiny:

5 14/16 is rounded to 6.

4x6=24.

20 is less than 24. So Destiny has more string

24-20=4. Destiny has around 4 more feet of string.

Destiny is estimated to have 4 more feet of string.​

Select the number line model that matches the expression -2/3 - 5/3

Answers

Answer:

  C.  None of the above

Step-by-step explanation:

You want an number line representation of the expression |-2/3 -5/3|.

Value

The expression is evaluated by performing the sum -2/3-5/3, then finding its absolute value. The sum is -7/3, and its absolute value is 7/3.

None of the number line diagrams shows the sum or its absolute value.

__

Additional comment

The sum would be shown by moving from 0 to -2/3, then moving an additional -5/3 to the point -7/3. The absolute value would reflect that across the 0 point to +7/3.
