Answer 1
Answer:

38 miles

Further explanation

Given:

A community bike ride offers a short 5.7-mile ride for children and families.

The short ride is followed by a long ride, 5²/₃ times as long as the short ride, for adults.

A woman bikes the short ride with her children, and then the long ride with friends.

Question:

How many miles does she ride together?

The Process:

Let us make a pattern for the short ride:

\boxed{5.7} \rightarrow in \ miles

Let us do a multiplication on a fraction at first.

\boxed{ \ = (2)/(3) * 5.7 \ }

\boxed{ \ = (2)/(3) * 5(7)/(10) \ }

\boxed{ \ = (2)/(3) * (57)/(10) \ }

We crossed out 3 and 57.

\boxed{ \ = 2 * (19)/(10) \ }

\boxed{\boxed{ \ = 3.8 \ }}

Then we make a pattern for the long ride, 5²/₃ (five and two third) times as long as the short ride:

\boxed{5.7}\boxed{5.7}\boxed{5.7}\boxed{5.7}\boxed{5.7}\boxed{3.8} \rightarrow in \ miles

A woman bikes the short ride with her children, and then the long ride with friends. Let's calculate how many miles does she ride together.

  • The short ride: \boxed{5.7 \ miles}
  • The long ride: \boxed{(5.7 * 5) + 3.8 = 28.5 + 3.8 = 32.3 \ miles}

\boxed{ \ 5.7 + 32.3 = 38}

Thus, she rides 38 miles together.

Answer 2
Answer: First multiply 5.7 by 5 2/3 to figure out how long the adult ride is: 5.7/1 X 17/3= 32.3. Then add the adult ride and the children's ride together: 5.7+32.3=38 (7+3=10 which adds 1 to the whole number). The mom would ride 38 miles :)

Answers

Answer:

x = 7, y = 6

Step-by-step explanation:

solve for y for the first equation

2x + y = 20

-2x         -2x , eliminate 2x

y = 20-2x

now that we have found y, substitute the y in for the second equation

-5y = -6x + 12

-5(20-2x) = -6x + 12, we just changed y into 20-2x. remember that we are multiplying all of 20 - 2x by -5

-100+10x = -6x + 12, we multiplied everything from the parathesis  by -5

+100                 + 100, eliminate -100

10x = -6x + 112

+6x    +6x , eliminate 6x

16x = 112 , solve for x

x = 7

then y = 20 - 2x = 20 - 2*7 = 6

check:

2 * 7 + 6 = 20

20 = 20

-5 * 6 = -6 * 7 + 12

-30 = -42 + 12

-30 = -30

First, you can draw a graph or coordinate plane to solve this. But i will do this for you.... OK, so the dimensions are correct, according to my graph... Don't worry, i did the coordinate plane for months in class... Your welcome and hope you do well for your hw. 

Geometry question, please explain how you got to the answer so that i can do it myself on other questions as well, thanks!

Answer:

AAS

Step-by-step explanation:

Here is the setting out proof with a - side note:

In Triangle JLM and Triangle JLK

Angle K is equal to Angle M (given) - This is a pair of matching angles

JK = JM (given) - This is a pair of matching sides

Since JL bisects KLM, Angle KLJ = Angle MLJ (Bisect means it cuts it in half, meaning the angle has been divided into two equal parts)  - This is a pair of matching angles.

Therefore, Triangle JLM and Triangle JLK are congruent (AAS) - The reason why we do AAS is because we have two pairs of matching angles and a pair of sides are equal. It is call AAS and not ASA, unknown reason but that is just how it is.

Answer:

AAS

Step-by-step explanation:

< K = < L  (given)

<KLJ = < MLJ ( because  JL bisects < KLM)

JK = JM  (given)

we have 2 equal angles and one equal side with the 2 angles adjacent.

Answer is AAS

Yolanda owns 4 rabbits. She expects the number of rabbits to double every year.Write an equation to model this situation.

Answers

R=Number of rabbits

y=Years that have passed by { y ≥ 0 }

R=f(y) --> R is a function of y.
---------------------------------------------

Note that when:

y=0, R=4 ---> Point: (0, 4)

y=1, R=8 ---> Point (1, 8)

y=2, R=16 ---> Point (2, 16)

y=3, R=32 ---> Point (3, 32)

y=4, R=64 ---> Point (4, 64)

--------------------------------------------

So the equation you want is going to form a curved graph.

That equation is:

R={ 2 }^( y+2 )

*You can test out this function on any decent graphing software.
This is an exponential function.

At year x, the number of rabbits would be as follows:

y=4e ^((x*(In2)))

Where x is the number of years
