Answer: r=8

Step-by-step explanation: -1.6r+5=-7.8

-16/10r+5=-78/10

-2^4/2.5r+5= -2X3X13/5

-2^3/5r+5= - 3X13/5

(-8r)+25/5=-3X13/5

=8 so r=8

Answer for brainlest for 25 points
Gnom [1K]

Answer:

1. 23/4  ,  2. 5.555...   , 3. 5 1/2   ,    4. √28

you want to make them all into decimals so you can compare then easier

23/4 would be 5.75

√28 (just put it in a calculator)  would be 5.29

5 1/2  would be 5.5  (make  it into a improper fraction 11/2 then do 11/2 and you get 5.5)

and you have 5.555.

so...

5.75

5.29

5.5

5.55555

first is 5.75 it's bigger because of the .(75)

then 5.555 because it's .(55)

then 5.5 because it's .(50)

and the last one 5.(29)

A specific park is rectangular-shaped and has a 3 mile-perimeter. The length is 4 times the width. What are the dimensions of th
avanturin [10]

Answer:

The length of the rectangular park is 1.2\ mi and the width of the rectangular park is 0.3\ mi

Step-by-step explanation:

Let

x ----> the length of the rectangular park

y ---> the width of the rectangular park

we know that

The perimeter is equal to

P=2(x+y)

P=3\ mi

so

3=2(x+y) -----> equation A

x=4y ----> equation B

substitute equation B in equation A and solve for y

3=2(4y+y)

3=10y

y=0.3\ mi

Find the value of x

x=4(0.3)=1.2\ mi

therefore

The length of the rectangular park is 1.2\ mi and the width of the rectangular park is 0.3\ mi
