Mrs brown used 3 3/4 liters of water to completely fill 3 water bottles.If each water bottle holds the same amount, how many lit
Svetradugi [14.3K]

Answer:

Each bottle could hold \frac{5}{4}\ liters of water.

Step-by-step explanation:

Given:

Total amount of water = 3\frac{3}{4}\ liters

Now 3\frac{3}{4}\ liters can be rewritten as \frac{15}{4}\ liters.

Total amount of water = \frac{15}{4}\ liters.

Total number of water bottles = 3

We need to find amount of water in each bottle.

Solution:

Now we can say that;

amount of water in each bottle can be calculated by dividing Total amount of water from Total number of water bottles.

framing in equation form we get;

amount of water in each bottle = \frac{\frac{15}{4}}{3}= \frac{15}{4\times3}=\frac{5}{4}\ liters

Hence Each bottle could hold \frac{5}{4}\ liters of water.

Solve 3 x - 9 x + 7 - 3 = -8.
erik [133]

Answer: x=2

3x−9x+7−3=−8

Step 1: Simplify both sides of the equation.

3x−9x+7−3=−8

3x+−9x+7+−3=−8

(3x+−9x)+(7+−3)=−8

−6x+4=−8

−6x+4=−8

−6x+4−4=−8−4

−6x=−12

−6x

−6

=

−12

−6

Apply the Pythagorean Theorem to find the distance between points A and B.
irinina [24]

Answer:          

  Properties of a right tangle can be created in  a Coordinate Plane

  Distance between two points A and B are shown as below

Step-by-step explanation:

Find distance between two point using Pythagorean Theorem.

Properties of right triangles and creating right triangle as a coordinate Plane.

Suppose two point are drawn in triangle containing value of  (-2 , 4 ) and (-2, -2)

then

In (-2 , 4 ) and (-2,-2)

taking y-values that is  4 and -2

find difference between them such as

    4-(-2) = 6

Distance is (-2,4) is 6 unit from (-2,-2)

We can also find unit length of A and B

Side A:   (-1, 2) and (3,2)

      3-(-2)  = 5

side A is 5 unit in length

Side B : (-2,2) and (-2,-1)

      2 - (-1) = 3

Side B is 3 unit in length
